Use of DAC, Generation of Signals
Use of DAC, Generation of SignalsThe main application DAC chips is to provide an analog signal from a sequence of digital codes.As a rule, codes are fed to the inputs of the DAC via the parallel register, which allows for simultaneous variation of all input bits of the DAC code. Voltage pulses appear at the DAC output during nonsimultaneous changing of bits of the input code. Their levels do not correspond to any one of the codes.However, even with a simultaneous change of all bits of the input code of the DAC code, the voltage level corresponding to the submitted code is not established immediately, but over the time response of the DAC, which is associated with imperfection of internal elements of the DAC.DAC output current is generally set much faster than the output voltage, as it does not depend on the inertia of the operational amplifier. It is clear that the condition for correct operation of the DAC is that the duration of keeping of the input code should be higher than the time response of the DAC, otherwise the output signal will not have time to take a value corresponding to the input code.If codes are submit to the input of the DAC rarely, the above scheme can be used, for example, in a controlled power supply with the output voltage specified by the input code. In this case high output current of the power supply should be provided, using an external power supply.If codes are supplied to the DAC input with a high frequency, we can get a generator (or a synthesizer) of analog signals of an arbitrary shape. In this case, codes supplied to the DAC, are called the sample codes (that is, of instantaneous values) of the generated analog signal. In the simplest case, a standard binary counter can be used as an input source code of the DAC.The DAC output voltage will increase with each clock pulse, forming sawtooth outputs. Duration of each step is equal to the period of the clock generator T, and the period of the entire output signal is equal to 2 raised to the power of "n" multiplied by T.Number of steps in the output signal period equals to 2 raised to the power of "n". If synchronous counters with a synchronous transfer are used in this circuit, no DAC input register is required, since all bits of the counter are switched simultaneously. If asynchronous counters or synchronous counters with asynchronous transfer are used, the DAC input register is required.In case we need to generate analog signals of arbitrary shape (e.g. sine, noise, ...

Sampling Signals Part 3 (2/4) - Audio Signal Quantizing
http://adampanagos.org In the previous video we examined the impact of downsampling an audio signal. In this video, we examine the impact of changing the number of quantization levels used to store the signal amplitudes. An original WAV music file is loaded in Matlab that uses 8-bit quantization. The signal is then re-quantized to both 6-bit and 4-bit quantization levels and plotted to visualize the impact of fewer quantization levels on the signal. While signals with fewer quantization levels require less storage space, it comes at the cost of introducing additional quantization error.

Understanding Wavelets, Part 1: What Are Wavelets
This introductory video covers what wavelets are and how you can use them to explore your data in MATLAB®. •Try Wavelet Toolbox: https://goo.gl/m0ms9d •Ready to Buy: https://goo.gl/sMfoDr The video focuses on two important wavelet transform concepts: scaling and shifting. The concepts can be applied to 2D data such as images. Video Transcript: Hello, everyone. In this introductory session, I will cover some basic wavelet concepts. I will be primarily using a 1-D example, but the same concepts can be applied to images, as well. First, let's review what a wavelet is. Real world data or signals frequently exhibit slowly changing trends or oscillations punctuated with transients. On the other hand, images have smooth regions interrupted by edges or abrupt changes in contrast. These abrupt changes are often the most interesting parts of the data, both perceptually and in terms of the information they provide. The Fourier transform is a powerful tool for data analysis. However, it does not represent abrupt changes efficiently. The reason for this is that the Fourier transform represents data as sum of sine waves, which are not localized in time or space. These sine waves oscillate forever. Therefore, to accurately analyze signals and images that have abrupt changes, we need to use a new class of functions that are well localized in time and frequency: This brings us to the topic of Wavelets. A wavelet is a rapidly decaying, wave-like oscillation that has zero mean. Unlike sinusoids, which extend to infinity, a wavelet exists for a finite duration. Wavelets come in different sizes and shapes. Here are some of the well-known ones. The availability of a wide range of wavelets is a key strength of wavelet analysis. To choose the right wavelet, you'll need to consider the application you'll use it for. We will discuss this in more detail in a subsequent session. For now, let's focus on two important wavelet transform concepts: scaling and shifting. Let' start with scaling. Say you have a signal PSI(t). Scaling refers to the process of stretching or shrinking the signal in time, which can be expressed using this equation [on screen]. S is the scaling factor, which is a positive value and corresponds to how much a signal is scaled in time. The scale factor is inversely proportional to frequency. For example, scaling a sine wave by 2 results in reducing its original frequency by half or by an octave. For a wavelet, there is a reciprocal relationship between scale and frequency with a constant of proportionality. This constant of proportionality is called the "center frequency" of the wavelet. This is because, unlike the sinewave, the wavelet has a band pass characteristic in the frequency domain. Mathematically, the equivalent frequency is defined using this equation [on screen], where Cf is center frequency of the wavelet, s is the wavelet scale, and delta t is the sampling interval. Therefore when you scale a wavelet by a factor of 2, it results in reducing the equivalent frequency by an octave. For instance, here is how a sym4 wavelet with center frequency 0.71 Hz corresponds to a sine wave of same frequency. A larger scale factor results in a stretched wavelet, which corresponds to a lower frequency. A smaller scale factor results in a shrunken wavelet, which corresponds to a high frequency. A stretched wavelet helps in capturing the slowly varying changes in a signal while a compressed wavelet helps in capturing abrupt changes. You can construct different scales that inversely correspond the equivalent frequencies, as mentioned earlier. Next, we'll discuss shifting. Shifting a wavelet simply means delaying or advancing the onset of the wavelet along the length of the signal. A shifted wavelet represented using this notation [on screen] means that the wavelet is shifted and centered at k. We need to shift the wavelet to align with the feature we are looking for in a signal.The two major transforms in wavelet analysis are Continuous and Discrete Wavelet Transforms. These transforms differ based on how the wavelets are scaled and shifted. More on this in the next session. But for now, you've got the basic concepts behind wavelets.

Amplitude Modulation - Matlab Tutorial (Amplitude modulation in Matlab with Code) 2016
Matlab Tutorial - Amplitude Modulation How to generate Amplitude modulation (AM) using MATLAB? AM is a method of transmitting signals, such as sound or digital information, in which the amplitude of carrier wave is changed according to the message signal. AM is widely used in electronic communication field. The plotting of AM signal using MATLAB is very easy. Here we are simply adding the carrier amplitude with message signal to obtain AM signal, then the instantaneous amplitude of carrier gets altered with respect to modulating signal. Thus the carrier amplitude varies according to the base band signal (message signal).

Lets crack this alien signal! The Wow! signal was a strong narrowband radio signal detected by Jerry R. Ehman on August 15, 1977, while he was working on a SETI project at the Big Ear radio telescope of The Ohio State University, then located at Ohio Wesleyan University's Perkins Observatory in Delaware, Ohio.[1] The signal bore the expected hallmarks of non-terrestrial and non-Solar System origin. It lasted for the full 72-second window that Big Ear was able to observe it, but has not been detected again.

Signal Synchronization
Signal Synchronization Signal synchronization is a standard procedure of signal timing. It may be provided by triggers. A trigger is the easiest device used to avoid spurious pulses of combinational circuit output which occur if several input signals are changed almost at the same time. In this case the synchronization requires a delayed sync signal transmitted with input data signal (or input code). A delay time shall exceed the delay time of the combinational circuit by t3. You can receive a signal without any spurious pulses by transmitting sync signal to C output of the trigger and output signal of the combinational circuit to D input of the trigger. If input code of a combinational circuit is changed on a regular basis, sync signal front may match input code change. In this case, signal will be transmitted to C input of the trigger earlier than D input signal will be changed due to the final delay factor of the combinational circuit. The trigger will not register any spurious pulses. In this case, trigger output signal will be delayed within the transmission period of T input code (or sync signal) towards output signal of the combinational circuit. Designed digital circuit operating according to timing signal generated by one clock generator often requires synchronization with any external signal. It means that you shall provide external signal changing according to timing signal of the clock generator. In this case, trigger may be used. Let's consider the simple example. Let transmission of clock generator signal is enabled or restricted by an external signal. In the simplest case, 2I logical element is used to enable or restrict clock generator signal. Herewith, reduced or minimum pulses as well as unstable pulses may be transmitted to circuit output which may result in circuit uncertainty. Synchronization trigger transmits only full length pulses to 2I logical element output. Enabling signal transmitted through the trigger and timed with the enabling signal is synchronized with a clock signal and provides transmission of full length pulses and full clock generator periods to the output.

Distress signals take the form of or are commonly made by using radio signals, displaying a visually detected item or illumination, or making an audible sound, from a distance. A distress signal indicates that a person or group of people, ship, aircraft, or other vehicle is threatened by grave and imminent danger and requests immediate assistance. Use of distress signals in other circumstances may be against local or international law... Maritime distress signals Distress signals at sea are defined in the International Regulations for Preventing Collisions at Sea and in the International Code of Signals... Aviation distress signals The civilian aircraft emergency frequency for voice distress alerting is 121.5 MHz. Military aircraft use 243 MHz (which is a harmonic of 121.5 MHz, and therefore civilian beacons transmit on this frequency as well). Aircraft can also signal an emergency by setting one of several special transponder codes, such as 7700. The COSPAS/SARSAT signal can be transmitted by an Electronic Locator Transmitter or ELT, which is similar to a marine EPIRB on the 406 MHz radio frequency. (Marine EPIRBS are constructed so as to float while aviation an ELT is constructed so as to be activated by a sharp deceleration and is sometimes referred to as a Crash Position Indicator/CPI). A "triangular distress pattern" is a rarely used flight pattern flown by aircraft in distress but without radio communications. The standard pattern is a series of 120° turns...

Strictly, they are radiobeacons that interface with worldwide offered service of Cospas-Sarsat, the international satellite system for search and rescue (SAR). When manually activated, or automatically activated upon immersion, such beacons send out a distress signal. The signals are monitored worldwide and the location of the distress is detected by non-geostationary satellites, and can be located by some combination of GPS trilateration and doppler triangulation. The basic purpose of a distress radiobeacon is to help rescuers find survivors within the so-called "golden day" (the first 24 hours following a traumatic event) during which the majority of survivors can usually be saved. Since the inception of Cospas-Sarsat in 1982, distress radiobeacons have assisted in the rescue of over 28,000 people in more than 7,000 distress situations. In 2010 alone, the system provided information which was used to rescue 2,388 persons in 641 distress situations... https://en.wikipedia.org/wiki/Flare A flare, also sometimes called a fusee, is a type of pyrotechnic that produces a brilliant light or intense heat without an explosion.

What is Pulse Code Modulation (PCM)
http://www.fiberoptics4sale.com/wordpress/what-is-pulse-code-modulation-pcm/ http://www.fiberoptics4sale.com/wordpress/ In a brief sentence, pulse code modulation is a method used to convert an analog signal into a digital signal. So that it can be transmitted through a digital communication network, and then converted back into the original analog signal. The PCM process includes three steps: Sampling, Quantization, and Coding. In the sampling process, the magnitude of the analog signal is sampled regularly at uniform intervals. The obtained values are called samples. For a 4 kHz voice channel, the sampling rate is 8000 Hz, which means the signal is sampled 8000 times per second. The samples will then be converted to digital numbers as we will see in the quantization process. Quantization is the process of converting the obtained samples into discrete digital values. The most basic type of quantization is called uniform quantization. In an uniform quantization, the vertical axis, which represents the amplitude, is divided into equal sized steps. As shown in this figure, the range between 1 volt and -1 volt is divided into 16 steps, each step represents 0.125 volt. All the samples whose amplitude falls within an step, take the same step value. However, the quantization process introduces an error. This is because that the real amplitude of a sample is replaced by an approximate value. This error is called quantization noise or quantization distortion. In uniform quantization, the quantization distortion presents a problem. For example, let's assume a quantization error of 0.05 volt, if this happens at a high level signal, such as 5 volt, the noise ratio is 0.05 volt divided by 5 volt, which is 1%, not too bad. But if the same quantization error happens at a low level signal, such as 0.5 volt, the noise ratio is 0.05 volt divided by 0.5 volt, which is 10%. Simply put, for uniform quantization, the signal to noise ratio is good at high level signals, but bad at low level signals. That is why non-uniform quantization was introduced. In non-uniform quantization process, the steps are not of equal size. Small steps are used for small signal values and large steps for large values. The purpose of doing so is to achieve that the signal-to-noise ratio is nearly independent of the signal level. This is done by favoring low-level voice over higher-level voice. In other words, more code groups are assigned to speech at low levels than at the higher levels, progressively more as the level reduces. This is shown in this figure. There are two types of non-uniform quantization methods in popular use today. They are the A-law and the u-law. Let's first look at the A-law. A law follows the logarithmic formula listed here, with A equals to 87.6. We can see that the curve consists of linear piecewise segments, seven above and seven below the origin. The segment just above and the segment just below the origin consists of two linear segments. Counting the collinear elements by the origin, there are 16 segments. Each segment has 16 8-bit PCM codes assigned. These are the codewords that identify the voltage level of a sample at some moment in time. Each codeword, often called a PCM "word", consists of 8 bits. The first bit tells the receiver if the sample is a positive or negative voltage. We can see that all PCM words above the origin start with a binary 1, and those below the origin start with a binary 0. The next 3 bits in sequence identify the segment. There are eight segments above the origin and eight below the origin. The last 4 bits, shown as XXXX, indicate exactly where in a particular segment that voltage line is located. The second is called u-law. It follows the logarithmic formula listed here with u equals to 100. The North American T1 system uses the u-law quantization and coding process. The process is similar to that of A-law. Colin Yao Sales Manager Fiber Optics For Sale Co. 1532 Centre Pointe Dr. Milpitas, CA 95035 Web: http://www.fo4sale.com

2.2 - Multiple Access - FDMA/TDMA/CDMA/OFDMA - Fundamentals of 4G (LTE)
Multiplexing is the process of combining multiple signals and transmitting them over a common channel and it is implemented on telecommunication using Multiple Access as a Application. Here, Multiple Access is explained with the example of Wi-Fi Hotspot sharing its internet connection among multiple users by providing them a frequency block over which they can transmit and receive data. The greater the size of this block, greater is the throughput. There are several way by which we can use Multiple Access Technique such as TDMA, FDMA, CDMA, W-CDMA, SDMA, OFDMA, SCMA. We have also mentioned, How TDMA and FDMA, CDMA, W-CDMA works and implemented in Earlier Generation system which is AMPS, GSM, GPRS, EDGE, UMTS, HSPA+. To overcome issues faced in earlier generation such as, - Low Throughput - Low Spectral efficiency - Resource wastage and many more, We have introduce next Generation Multiple Access technique which is already deployed in WIFI and in WIMAX, but due to lack of backward compatibility and support for Mobile communication in WiMAX, Operator started to working OFDM to include in LTE.

Code Division Not Frequency Division
Code Division Not Frequency Division We are all familiar with one signal channel per frequency. How the heck do you put multiple signal channels into one wide frequency? Orthogonal signals such as Walsh (Hadamard) codes support doing this. (Sines and Cosines are orthogonal analog signals.) See the Wiki entry on IS-95, cdmaOne, or first generation cdma, especially the forward (cell tower to mobile) direction. The reverse direction (mobile to cell tower) still depends on orthogonal coding, but it uses very long codes and not Walsh codes.

Secrets Of Body Language
Body language is a form of non-verbal communication, which consists of body posture, gestures, facial expressions, and eye movements. Humans send and interpret such signals almost entirely subconsciously. John Borg attests that human communication consists of 93 percent body language and paralinguistic cues, while only 7% of communication consists of words themselves; however, Albert Mehrabian, the researcher whose 1960s work is the source of these statistics, has stated that this is a misunderstanding of the findings. Others assert that research has suggested that between 60 and 70 percent of all meaning is derived from nonverbal behavior. Delve into the science of non-verbal signals as this very visual and highly entertaining expose reveals the hidden language in which 93% of human communication takes place. From President Franklin D.

Processing all of this information is a gargantuan task that would require a massive supercomputer that SETI can’t quite afford. So they came up with a brilliant idea. It’s called SETI at home. It’s a program you can install on your computer that processes tiny parts of that data in the background. Spreading that data across thousands of computers around the world, they’re able to crank through mountains of information, without the mountainous cost of a supercomputer. But back in the 70’s none of that existed. Signals from space had to be printed out and processed by hand. Which is exactly what astronomer Jerry Ehman was doing on August 18th, 1977. He was going over reams of printouts when he found a massive spike in a certain frequency of radio wave. It was a spike 30 times higher than the background noise, and it was so noteworthy, he literally wrote “Wow” on the page. It has since become known as the wow signal, and it’s still confusing scientists 40 years later. The Big Ear went into operation in 1963 and was initially put to use on the Ohio Sky Survey, which catalogued nearly 20,000 sources of radio waves between 1965 and 1971. Since it was on the ground, the telescope basically used the rotation of the Earth to scan across the sky. When it measured a radio signal, they could infer by the time of day what direction the telescope was pointing and match that with visual sky surveys to figure out what star or galaxy it came from. In 1956 on the grounds of Ohio Wesleyan University, construction crews broke ground on a massive telescope the size of three football fields to monitor the sky for radio signals from deep space. It was officially known as the Ohio State University Radio Observatory, because it was actually run by Ohio State, but it was more well known by its nickname. The Big Ear. The Big Ear went into operation in 1963 and was initially put to use on the Ohio Sky Survey, which catalogued nearly 20,000 sources of radio waves between 1965 and 1971. Since it was on the ground, the telescope basically used the rotation of the Earth to scan across the sky. When it measured a radio signal, they could infer by the time of day what direction the telescope was pointing and match that with visual sky surveys to figure out what star or galaxy it came from. So a popular misconception with the wow signal is that 6EQUJ5 is some kind of alien code that we received but it’s actually just a measure of signal strength. Ehrman and others immediately started pointing telescopes at the spot where the signal originated, which is in the constellation Sagittarius, but nothing has ever shown up. So, it’s not a star or galaxy or pulsar or black hole because we’d pick up more signals from that location. As far as we know, and we’ve looked there a lot at this point, there’s nothing there. At least, no cosmic body that would normally produce a radio stream like that. But the mystery actually gets deeper. Because the frequency that this signal was found on was 1420 MHz. And if you were paying attention in last week’s video about the Voyager missions, 1420 mHz is the frequency that hydrogen atoms expel photons during hyperfine transitions. (also known as 21-centimeter line or hydrogen line) This same frequency was used by Carl Sagan and Frank Drake when creating the Pioneer and Voyager plaques as a way to communicate with an alien species should they ever come across the spacecraft.

10 Cell Phone Life Hacks, For Better Reception
See how opening a window can double your cell phone signal, and explore 9 other tips and tricks for finding better cell phone reception. Some quick links to a few of the materials I used: [✓] weBoost home unit 1500 sq ft: http://amzn.to/2clkj7f [✓] weBoost Connect 7500 sq ft: http://amzn.to/2c9Txji Learn more about cell phone signal boosters and the science behind them on weBoost's website at: http://bit.ly/1Nabf1D In this video you'll see how to; - Access a secret “Field Testing” screen on your iPhone. - Learn how to see the ACTUAL strength of your signal. (“Bars” aren't usually accurate.) - Find the cell tower you're connected to right now, and make a “real life” connection with it. - Force your phone to latch onto stronger signals nearby. - Prevent texts, and voicemails, from coming through delayed. - Double your signal, simply by rolling down a window. - Find which carrier best covers the area where you live, and whether you should switch. - Use a “Femtocell” or “Cell-spot Router” to re-direct calls through the internet. - Use “Wi-Fi Calling” mode to send messages from the sky, and save on international roaming charges. - Use a “weBoost” signal booster to eliminate dead-zones and dropped calls in your home, office, or car.

Music By: “Through The Flame” Instrumental iTunes: http://bit.ly/ScottBrendoiTunes YouTube: www.youtube.com/scottandbrendo Project History & More Info: FTC Disclaimer: This video was sponsored by my friends at weBoost. (#ad) Project Inspired By: weBoost.com. The weBoost staff reached out and invited me to collaborate on a video idea for their new line of weBoost products. About a month ago, they reached out to see whether I had ever heard about cell phone signal boosting. It was actually a new concept to me, even though they'd been selling products like this for over a decade, under the name “Wilson Electronics”. Our house has always had trouble with reception, so I had one of their systems installed so I could test it for myself, and measure the results before making claims on what it could do. I did a fair amount of research on how cell phone technology works in general, and different ways signals could be enhanced. And since most people don't have any idea how phones work or where the signals come from, I thought it would be appropriate to make a video with tips and tricks that people could try out themselves, to learn and explore the invisible radio world around them. Originally my thinking was to create a number of different projects that could be done with the weBoost system itself, or projects that related to the concepts of signal boosting. Among these ideas were; - Making a mini radio you could use to broadcast your voice on your kitchen radio. - Building a mini audio amplifier powerful enough to drive a large 8ohm speaker. - Ripping the weBoost amplifier apart, and seeing how it could re-purposed for something else. In the end I felt that a “Life Hack” video showing 10 tips and tricks, would be the best. I created the video to show 10 ways you could find, or create, better signals, but I also tried to design it so you'd be learning more about how the cellular system works, at the same time. There is a lot of education mixed in with the projects. So in a way it's kind of like a mini training course that'll get you involved with understanding the networks you've always used, but never really been aware of. I hope you learned something new you can start using. And if not, please watch the video again. There's a really good chance you'll see something you missed the first time around :) Remember to visit https://www.weboost.com/us/ and enter the promo code “48hrskingofrandom” for 20% off 3G products.
