Advantages and Disadvantages of Digital Communication System [HD]
 
12:44
Here you will know, why digital communication is preferred to analog communication. We will also discuss Disadvantages along with advantages of digital communication. For more detailed description, visit my blog (link below) http://www.engineeringmadeeasypro.com/ 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.

ASK FSK PSK Modulation/Digital Modulation Techniques/Amplitude, Frequency and Phase Shift Keying
 
13:13
For More Detailed Knowledge and Lots of Interesting Stuff, You Should Visit My BLOG At Least Once- https://www.engineeringmadeeasypro.com/ This Video discusses Digital Modulation Techniques (ASK, FSK and PSK). The Waveforms, Definition and Basic Concepts of each digital modulation Techniques are discussed here. This Video also explains the basic difference between digital modulation and analog modulation. The digital modulation techniques are amplitude shift keying (ASK), frequency shift keying (FSK) and Phase shift keying (PSK). First of all let's understand, what is modulation? Modulation is a process, where some characteristic of the carrier wave (amplitude, frequency or phase) is varied in accordance with the instantaneous value of the modulating (message or baseband) signal. So if amplitude of the carrier wave is varied, then it is called as amplitude modulation, but if frequency or phase of the carrier wave is varied, according to the instantaneous value of the modulating signal, then it is known as frequency modulation or phase modulation respectively. So now let's Understand the basic difference between continuous wave modulation and digital modulation- Difference between Continuous Wave Modulation and Digital Modulation- Amplitude Modulation (AM), Frequency Modulation (FM) and Phase Modulation (PM) are the examples of Continuous Wave (CW) modulation, while Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK) and Phase Shift Keying (PSK) are examples of Digital Modulation Techniques. The basic difference between continuous wave Modulation and digital modulation techniques is based on the nature of message signal (modulating signal). In continuous wave modulation, the message signal is of analog nature but in digital modulation, the message signal is of digital nature (Binary or M-ary encoded version). In both of these modulation techniques, the carrier wave is of analog form. Here it is interesting to note that, the three forms of digital modulation techniques that is ASK, FSK and PSK are analogous to AM, FM and PM of continuous wave modulation respectively. So now let's discuss each digital modulation technique (ASK, FSK and PSK) in detail- Amplitude shift keying (ASK) In ASK, the amplitude of the carrier wave is changed (switched) according to the digital input signal (modulating signal). Therefore amplitude shift keying is analogous to Amplitude Modulation (analog modulation). ASK is analogous to AM, because in Amplitude Modulation (AM), amplitude of the carrier wave is changed according to the instantaneous value of the modulating (message) signal, in the same way in ASK also, the amplitude of the carrier wave is switched (varied) according to the instantaneous value of the modulating signal (digital input signal). The difference is only of the nature of the modulating signal. In amplitude modulation, the modulating signal is of analog kind but in digital modulation, it is a stream of digital bits. the amplitude of the sinusoidal carrier wave is switched, as per the digital input signal. The carrier wave is either not transmitted or transmitted for digital input signal '0' or '1' respectively. That is why amplitude shift keying (ASK) is also called as "ON - OFF Keying (OOK)". Now we will discuss the Frequency Shift Keying (FSK) Frequency Shift Keying (FSK) If the frequency of sinusoidal carrier wave is varied (switched) as per the digital input signal, then it is known as the frequency shift keying (FSK). It is analogous to frequency modulation (analog modulation). The reason behind why FSK is analogous to FM, is.... In Frequency Modulation (FM), the frequency of the carrier wave is varied according to the instantaneous value of the modulating signal, in the same way in frequency shift keying also, the frequency of the sinusoidal carrier wave is varied (switched) as per the digital input signal. The difference is only of the nature of the modulating signal. In FM the modulating signal is of analogue nature while in FSK modulating signal is digital. So here the basic purpose of Frequency Shift Keying (FSK), is to modulate (change/switch) the frequency of the carrier wave, according to the digital input signal. So in Frequency Shift Keying (FSK), we have two types of frequencies of the carrier wave, low frequency for the transmission of '0' and high frequency for the transmission of '1'. In this way, in Frequency Shift Keying (FSK), the information of the digital input signal is present in the frequency variations of the carrier wave. That is why it is known as frequency shift keying. Now let's discuss the Phase Shift Keying (PSK) 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

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! = 0612 TV = 0612 TV, a sub-project of NERDfirst.net, is an educational YouTube channel.

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.

Analog Communication and Digital Communication | Physics Video Lectures
 
04:14
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.

Sampling and Quantization of Analog Signal [HD]
 
07:16
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. For more details you can visit my BLOG- http://www.engineeringmadeeasypro.com/ 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.

Coherent and Noncoherent Digital Modulation Techniques/Coherent and Noncoherent Detection [HD]
 
05:59
This video lecture discusses Coherent and Noncoherent Digital Modulation Techniques. Here Coherent Vs Noncoherent Detection is explained. Various Advantages (Benefits) and Disadvantages (Drawbacks) of Coherent and Noncoherent Detection techniques are covered. Some Digital modulation techniques use Synchronous detection where the local carrier and carrier at the transmitter are phase locked. they are synchronized (coherent) in both frequency and phase. While the Noncoherent detection does not require the two oscillators (Carriers) to be phase locked. Coherent Vs Non Coherent Modulation (Introduction) On the Basis of presence of Phase-Recovery circuit, we can classify digital modulation techniques into coherent or non coherent techniques. The job of the phase recovery circuit is to keep the oscillators supplying locally generated carrier wave at the receiver; in synchronizm to the oscillator supplying carrier wave at the transmitting end. Actually, We use carrier waves at the transmitting and receiving ends both and for coherent detection these two Carriers should be in synchronism. Here synchronism means, synchronization in both frequency and phase. Coherent Digital Modulation Technique This technique employs coherent detection, the local carrier wave which is generated at the receiver is phase locked with the carrier at the transmitter. Hence both the oscillators (carrier waves) are synchronized in both frequency and phase. In coherent digital modulation technique, The error probability decreases but the system becomes complex. Non Coherent Digital Modulation Technique In non coherent digital modulation technique, there is no need for the two carriers (at transmitter and receiver) to be phase locked. Although in non-coherent technique the system becomes simple but the error probability increases which is in contrast to the coherent detection method.

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.
