COMMUNICATION SYSTEMS: BANDWIDTH OF SIGNAL: In a communication system, the message signal can be voice, music, picture or computer data. Each of these signals has different ranges of frequencies. The type of communication system needed for a given signal depends on the band of frequencies which is considered essential for the communication process. For speech signals, frequency range 300 Hz to 3100 Hz is considered adequate. Therefore speech signal requires a bandwidth of 2800 Hz 3100 hertz – 300 hertz for commercial telephonic communication. To transmit music, an approximate bandwidth of 20 kHz is required because of the high frequencies produced by the musical instruments. The audible range of frequencies extends from 20 Hz to 20 kHz. Video signals for transmission of pictures require about 4.2 MHz of bandwidth. A TV signal contains both voice and picture and is usually allocated 6 MHz of bandwidth for transmission.In the preceeding paragraph, we have considered only analog signals. Digital signals are in the form of rectangular waves as shown in Figure. However, for practical purposes, the contribution from higher harmonics can be neglected, thus limiting the bandwidth. As a result, received waves are a distorted version of the transmitted one. If the bandwidth is large enough to accommodate a few harmonics, the information is not lost and the rectangular signal is more or less recovered. This is so because the higher the harmonic, less is its contribution to the wave form.

Communication electronics can be classified as, (i) Analog communication and (ii) Digital communication In analog communication, analog signals are used. An analog signal is a continuously varying voltage or current. Traditionally, in telephone and radio systems, the messages consisted of information conveyed by voice.Shortcomings of analog communication is also explain in this video. A digital communication system offers many advantages to the user, that cannot be achieved with an analog system. Digital communications system may make use of analog links and concepts.The term data is commonly used in digital communication systems. Data is any form of information, that has been put into digital form, so that it can be handled by a digital system. Advantages (i) The transmission quality is high and almost independent of the distance between the terminals. (ii) The capacity of the transmission system can be increased. (iii) The newer types of transmission media such as light beams in optical fibers and wave guides operating in the microwave frequency extensively use digital communication. Disadvantages (i) A digital system requires larger bandwidth. (ii) It is very difficult to gradually change over from analog to digital transmission.

Advantages and Disadvantages of Digital Communication System [HD]
 
12:44
Visit My BLOG for more Details- www.engineeringmadeeasypro.com Here you will know, why digital communication is preferred to analog communication. We will also discuss Disadvantages along with advantages of digital communication. We know, that the electronic communication can either be analog or digital. Today’s world is going digital, so it is really important to understand, the advantages of digital communication, that are responsible for the digitalization everywhere. So here in this post, we will see, why digital communication is preferred over analog communication? But there are also some disadvantages associated with the digital communication. These disadvantages will also be discussed here. So first let's start with the advantages of digital communication. Advantages of digital communication # Digital communication systems are simpler and cheaper in implementation as compared to analog communication systems. It has become possible due to advancements in Integrated Circuits (IC) technology. These ICs are very small in size, reliable and cost-effective. Such ICs are used in digital communication, # In digital communication, it is possible to use multiplexing to merge speech, video and other forms of data for transmission over a common channel. The multiplexing is of various types like Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM) or Code Division Multiplexing (CDM). I don’t want to deviate from the current topic, so I will discuss the multiplexing in separate post. # High level of privacy can be obtained in digital communication using data encryption technique. This privacy provides the facility to allow the transmitted signals, to be received only by the permitted receivers. This feature is of great importance in military applications. # In digital communication channel encoding is used. Because of this encoding, there is less accumulation of noise from repeater to repeater, in case of long-distance communication. Apart from this, the digital signals tend to be less affected by noise as compared to analog signals. # It is possible to perform lots of operations on digital signals, like Digital Signal Processing (DSP), data compression, image processing etc. # It is easy to detect and correct errors in digital communication. This easy detection and correction of errors is possible due to the use of channel coding in digital communication. So these were the advantages of using digital communication. These benefits encourage the use of digital communication in place of analog communication. Now we will discuss some disadvantages that are associated with the digital communication. Disadvantages of digital communication # More transmission bandwidth is required in digital communication as compared to analog communication. This is due to the increase in the data rate when analog signal is converted into digital signal. # In digital communication, in case of synchronous modulation, synchronization is required. # Due to various stages used in conversion, high power consumption is another drawback of digital communication. # Sampling error is introduced in the sampling of signal. # Circuits that are used in digital communication are comparatively more complex and sophisticated. So this was the discussion about both advantages and disadvantages of digital communication but it’s worth mentioning that the advantages of using digital communication are more in comparison to disadvantages. Therefore digital communication is replacing analog communication nowadays. This video is created by Lalit Vashishtha, Founder and owner of 'Engineering Made Easy, YouTube Channel.

Sampling and Quantization of Analog Signal [HD]
 
07:16
Visit My BLOG for more Details- www.engineeringmadeeasypro.com This video discusses sampling and quantization of analog signal with the help of waveform of sampled signal and quantized signal. The sampling and quantization technique s used in pcm to convert analog signals into binary signals. Sampling of signal The second part of this image, shows the sampled signal. In the process of sampling of the signal, we convert the continuous time signal into discrete time signal. You can see this conversion in the sampled signal shown in the image. The analog signal was continuous in time, since it had some value at every instant of time. But in the sampled signal, which is discrete in time, the value of the signal is present only at certain instants of time. Accuracy of the sampling increases with increase in frequency of the sampling. But some sampling error is introduced because of this sampling process, since it is not possible to have infinite sampling frequency practically. Sampling of the analog signal is performed with the help of sampling theorem. So let me define here, what is sampling theorem. Sampling Theorem:- A continuous-time signal can be completely represented in its samples and recovered back into its original form if the sampling frequency is greater than or equal to twice the highest frequency present in the modulating signal (message signal). It can be represented mathematically as- fs is greater than or equal to 2fm Here 'fs' is the sampling frequency and 'fm' is the highest frequency present in the modulating signal. Quantization of Signal To understand the process of quantization look at the image given above. In the process of quantization, amplitude of the signal is cut horizontally into a number of fixed levels. Now the value of the signal is rounded-off (approximated) to the nearest level of amplitude. These certain levels of amplitude are shown in the image on the vertical axis. Here we have divided the amplitude range (peak to peak amplitude) into 'l' number of levels. The magnitude of each level is equal to the peak to peak amplitude range divided by the number of levels. It is important to note here that, quantized signal is just an approximation of the original signal. As the number of levels increases, the accuracy of quantization increases. Pulse Code Modulation (PCM) technique uses the process of quantization to convert analog signals into digital signals.

Wireless communication system matlab code
 
08:09
=================================================== Get the code + report from here: https://gum.co/dbqm =================================================== In this code I build and simulate a wireless communication system on matlab. Any communication system is formed of three main components: a transmitter, a channel and a receiver. The information source sends the message signal via the transmitter and the signal is conducted to a receiver via a channel where it can be overlapped with noise. The signal is received and fed to the user of information. The transmitter is mainly a cascade of a source encoder, a channel encoder and a modulator while the receiver is a cascade of a demodulator, a channel decoder and a source decoder. The purpose of this project is to simulate the basic components of an analog communication system using MATLAB programming. An AM modulator and a corresponding receiver are simulated. There are two different transmission schemes: Frequency division multiple access and quadrature amplitude modulation. In this project the first scheme is simulated. Also with the code files you will find a detailed report (.docx file so you can edit it) with all codes details and scientific idea used in building it.

Sampling, Aliasing & Nyquist Theorem
 
10:47
Sampling is a core aspect of analog-digital conversion. One huge consideration behind sampling is the sampling rate - How often do we sample a signal so we can accurately recreate it? This may seem trivial at first, but serious problems can arise if we use a bad sample rate, as this can lead to aliasing - The failure to reconstruct the original signal, causing it to appear as a completely different wave of a lower frequency. To combat this problem, we have to make use of the Nyquist-Shannon Sampling Theorem, which tells us what sample rate to use to prevent aliasing from happening. Today, we take a look at all these points and see just how they link together, to allow us to have the common sample rates (eg. 44100 Hz) we see today! Want to see it for yourself? Try your hands on this interactive web application, and see how sampling rate and the quality of the reconstructed signal go hand in hand! https://resources.nerdfirst.net/sampling = 0612 TV = 0612 TV, a sub-project of NERDfirst.net, is an educational YouTube channel.

Signal Processing and Communications Hands On Using scikit dsp comm | SciPy 2017 Tutorial | Mark Wic
 
03:44:23
Tutorial materials found here: https://scipy2017.scipy.org/ehome/220975/493423/ In this tutorial I intend to start with a basic review of discrete-time signals and systems using a module I developed for my book Signals and Systems for Dummies. Once a basic foundation is provided, all using hands-on Python code examples in a Jupyter notebook, I will move to more advanced topics relative to statistical signal processing, digital communications and software defined radio. Digital communication transmitter and receiver simulations will be explored using Python code modules found in the newly posted scikit-dsp-comm as well as data acquisition code used in conjunction with a popular $20 software-defined radio USB dongle (RTL-SDR). The capstone portion of the tutorial will have the students write code to recover FM stereo radio broadcasts from a raw complex signal file obtained from the output of a popular $20 software defined radio module (the RTLSDR). Hardware will be provided for small groups to work together.

analog and digital signals in hindi
 
03:54
Analog Signal:- An analog signal is a continuous wave denoted by a sine wave (pictured below) and may vary in signal strength (amplitude) or frequency (time). The sine wave's amplitude value can be seen as the higher and lower points of the wave, while the frequency (time) value is measured in the sine wave's physical length from left to right. There are many examples of analog signals around us. The sound from a human voice is analog, because sound waves are continuous, as is our own vision, because we see various shapes and colors in a continuous manner due to light waves. Even a typical kitchen clock having its hands moving continuously can be represented as an analog signal. Digital Signal A digital signal - a must for computer processing - is described as using binary (0s and 1s), and therefore, cannot take on any fractional values. As illustrated in the graphic below, digital signals retain a uniform structure, providing a constant and consistent signal. Because of the inherent reliability of the digital signal, technology using it is rapidly replacing a large percentage of analog applications and devices. For example, the wristwatch, showing the time of day, with its minute, hour, and sweeping second hands, is being replaced by the digital watch, which offers the time of day and other information using a numerical display. A typical digital signal is represented by 1s and 0s .

Vij (former Professor of Physics, Kurukshetra University, India) primarily aims at taking free education to the doorsteps of learners who for various economic and social factors can not avail benefits of regular coaching. In view of the congested classrooms coupled with hefty tuition fee, social taboos and hazards of travelling (for girls in particular) this mode of extending education had become a necessity. This self-learning approach is a definite step towards democratisation of education i.e. taking education even to individuals who staying in remote and far off areas were being deprived of education for no fault of theirs. Viewers are requested to click LIKE button if they like a video and SUBSCRIBE to this channel to get notifications of more video lessons being uploaded from time to time in future.

Binary Phase Shift Keying (BPSK) Generation Block Diagram/PSK Modulation Generation/Modulation [HD]
 
14:07
Visit My BLOG for more Details- www.engineeringmadeeasypro.com This video explains the Generation of Binary Phase Shift Keying Modulation (BPSK). Block Diagram for the generation (Production) of BPSK has been given to clear the basics. You will get the Basic introduction, Definition and Waveform of Binary Phase Shift Keying Modulation (BPSK). Here we will also discuss the derivation of the Binary Phase Shift Keying (BPSK Modulation) equations. The conceptual difference between digital modulation and analog modulation is also explained here. You will also know how the Analog Phase Modulation (PM) and Phase Shift Keying (PSK) are different from the Binary Phase Shift Keying (BPSK Modulation). Phase Shift Keying (PSK) In phase shift keying, phase of the carrier wave (analog) is varied as per the digital input signal. Phase shift keying is analogous to Phase Modulation (analogue phase modulation). The phase shift keying is very much similar to Phase Modulation (PM), because in both of these modulation techniques, the phase of the carrier wave is changed, according to the instantaneous value of the modulating signal. The difference is only of the nature of the modulating signal. In phase modulation, the modulating signal is analog but in case of phase shift keying, modulating signal is of digital nature. The carrier wave is of analogue kind in both of these modulation techniques. Now we will understand the basic concept of Phase Shift Keying (PSK), with the help of an example shown in the image given below- Phase Shift Keying, PSK, PSK Waveform, Phase Shift Keying (PSK) Waveform Phase Shift Keying (PSK) Waveform The Image contains three parts- #The digital input signal (011001) #The sinusoidal carrier wave (analog) #PSK waveform Now let's understand the basic concept, how the phase shift keying takes place- In Phase Shift Keying (PSK), the phase of the carrier wave is changed (switched) according to the digital input signal. Therefore the information of this digital input signal is present in the phase shift variations of the carrier wave. Now observe the image carefully- Here we will Try to understand the concept of PSK with the help of an example given in this image. Notice here that, whenever the digital input changes the bit (either from '0' to '1' or from '1' to '0'), a phase shift of 180 degrees (π) takes place in the carrier wave. But no phase change occurs when there is no change in the digital bit. In this image, observe; the phase shift of 180 degrees takes place in the carrier wave at three places. At all these three places, the digital input bit has either change from '0' to '1' or from '1' to '0'. No phase shift takes place when two two successive (back to back) 1's or two successive 0's are to be transmitted (as per the image). Hence we get the PSK waveform in this way. This was all about three kinds of digital modulation techniques, amplitude shift keying, frequency shift keying and phase shift keying. .
