🔴 MODULATION - DEMODULATION || AMPLITUDE 🆚 FREQUENCY || Communication System - Part 4 || in HINDI
 
22:19
In this Physics video lecture in Hindi for class 12 we explained modulation and demodulation in communication system. Amplitude modulation and frequency modulation are two types of analog signal modulation explained here. We explained the necessity of modulation and demodulation. We also differentiate between them. Modulation is required in communication system for the following reasons: 1) Baseband signals have less energy due to their low frequency. We mix up high frequency carrier waves with the baseband signel and get modulated signal during modulation process. Due to its high frequency, and hence high energy, signal can propagate a long distance without being attenuated. 2) To distinguish the signals from different stations we use modulation technique. 3) If the baseband signal is propagated, due to its high wavelength the antenna needed to receive or emit signal would be of impractically large length. ★★★★★★★★★★★★★★★★ Click to visit the homepage of our channel : https://www.youtube.com/channel/UCG1-22fo1sIhXGuXYpTRqaA Arijit Daripa EduPoint, Dam Road, Chandil, Dist- Seraikela-Kharsawan, Jharkhand, India.

ASK FSK PSK Modulation/Digital Modulation Techniques/Amplitude, Frequency and Phase Shift Keying
 
13:13
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). For More Details Visit My BLOG - https://www.engineeringmadeeasypro.com/ Please Support me on Patreon https://www.patreon.com/user?u=20310205 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 #Modulation #modulationTechniques

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 Visit My BLOG - https://www.engineeringmadeeasypro.com/ Please Support me on Patreon https://www.patreon.com/user?u=20310205 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.

Sampling Theorem and Reconstruction (Sampling and Quantization) [HD]
 
09:51
This video explains in detail sampling, sampling theorem and reconstruction, nyquist theorem and quantization of analog signal with the help of waveform of sampled signal. The sampling and quantization techniques used in pcm to convert analog signals into binary signals. For more details you can visit my BLOG- http://www.engineeringmadeeasypro.com/ SAMPLING THEOREM AND RECONSTRUCTION (SAMPLING AND QUANTIZATION) What is Sampling and why it is required? A continuous time signal at the transmitting end is converted into discrete time signal, it is done as it is easier to process digital signals in comparison to analogue signals. If we want to convert analogue signals into digital signals then first of all continuous time signal is converted into discrete time signal with the help of sampling process and after this process, this sampled signal is converted into digital signal by the process of quantization. Sampling Theorem: A continuous time signal can be completely represented in its samples and then can be recovered back, if the sampling frequency is greater than or equal to the twice of the maximum frequency present in the signal. i.e. 'fs' is greater than or equal to '2fm' Here fs is sampling frequency fm is maximum frequency present in the signal. It is essential to take sufficient number of samples to completely represent a signal by its samples and also to reconstruct the signal back to its original form from its samples.

Pulse Code Modulation (PCM)/Block Diagram of PCM Transmitter/Sampling Quantizing and Encoding in PCM
 
10:52
For More Detailed Knowledge and Lots of Interesting Stuff, You Should Visit My BLOG At Least Once- https://www.engineeringmadeeasypro.com/ This video is about basics of pulse code modulation. Here you will learn the block diagram of pulse code modulation transmitter. This video explains basic building blocks of pulse code modulation system like PCM transmitter, PCM receiver and PCM transmission path. In this video you will learn, how the process of low pass filtering, sampling and quantization takes place along with the encoding in the PCM transmitter. PCM is the digital form of pulse modulation technique. This form of pulse modulation technique is known as Pulse Code Modulation (PCM). Pulse code modulation is a technique to convert analog signals into digital signals. After converting the signal into digital form, it becomes possible to transmit the digital signal through digital communication network and at the receiving end, it is converted back into it's original analog form. Pulse code modulation process involves the following three stages #Sampling #Quantization and #Coding Following are the Advantages and Disadvantages of Pulse Code Modulation (PCM) Advantages of Pulse Code Modulation 1.Very high noise immunity 2.In pulse code modulation repeaters are used between the transmitter and receiver. Repeaters are used to regenerate the received PCM signal. Use of repeaters is possible due to digital nature of the signal. 3.Effect of noise is further reduced due to the use of repeaters. 4.Due to its digital nature we can easily store PCM signals. 5.One more advantage of using PCM is security of the signal. We can use various kinds of coding techniques so that only the desired person can decode the received signal. Disadvantages of Pulse Code Modulation 1.Pulse code modulation requires large bandwidth as compared to other techniques. 2.The encoding, decoding and quantizing circuitry of PCM is quite complex.
