🔴 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
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

Pulse Modulation Techniques (PAM, PWM, PPM, PCM)/Pulse Amplitude,Pulse Width,Pulse Position, Code
 
45:26
For More Detailed Knowledge and Lots of Interesting Stuff, You Should Visit My BLOG At Least Once- https://www.engineeringmadeeasypro.com/ Here we will discuss in details, Pulse modulation and pulse modulation techniques like Pulse Amplitude Modulation (PAM), Pulse Width Modulation (PWM), Pulse Position Modulation (PPM) and Pulse Code Modulation (PCM). Here Basics and waveform of each Pulse Modulation Technique has been discussed in detail. Pulse Modulation Techniques Here I have discuss different kinds of pulse modulation techniques. Before starting the topic, it is important to understand the basic difference between Continuous Wave Modulation and Pulse Modulation. In Continuous Wave Modulation (Amplitude Modulation, Frequency Modulation, Phase Modulation) the carrier wave used is continuous in nature, while in case of pulse modulation, the carrier wave is in the form of pulses. So now let's discuss different types of Pulse Modulation Techniques in detail- Pulse modulation can be categorized broadly into two types- #Analog and #Digital The analog modulation can again be of two types- #Pulse Amplitude Modulation (PAM) #Pulse Time Modulation (PTM) The Pulse Time Modulation (PTM) can further be classified into two types of modulation- #Pulse Width Modulation (PWM)/Pulse Duration Modulation (PDM) #Pulse Position Modulation (PPM) Pulse Code Modulation (PCM) is a digital pulse modulation technique. You can see the classification of pulse modulation To see the classification of all types of modulations including pulse modulation and continuous wave modulation, look at the image given below (Click to enlarge)- Here we will discuss all types of pulse modulation techniques i.e. Pulse Amplitude Modulation (PAM), Pulse Width Modulation (PWM)/Pulse Duration Modulation (PDM), Pulse Position Modulation (PPM) and also Pulse Code Modulation (PCM). So let's start with Pulse Amplitude Modulation (PAM)- Here we will see the definition of pulse amplitude modulation and waveform of pulse amplitude modulation. Pulse Amplitude Modulation (PAM) Definition:- The modulation technique in which the instantaneous amplitude of the pulsed carrier is varied according to the modulating signal (message signal) is called as pulse amplitude modulation. Waveform of pulse amplitude modulation Look at the image given below carefully to understand the formation of pulse amplitude modulated wave. Here in this image, you can see, three waveforms. The first waveform is of modulating signal (message signal), the second one is of the pulsed career wave and the third waveform is of the pulse amplitude modulated wave (PAM). The message signal can have multiple frequencies and variable amplitude. Here we have used a sinusoidal message signal. The carrier wave that we have used here, is a train of pulses having high frequency. Since we know that in Pulse modulation, the carrier wave is in the form of pulses. Now we will understand how can we make pulse amplitude modulated wave (PAM). As we have discussed that in Pulse amplitude modulation, the instantaneous amplitude of the pulsed carrier is varied according to the modulating signal (message signal). Now look at the image shown above very carefully, observe that, as the amplitude of the modulating signal (message signal or baseband signal) increases, the amplitude of the pulsed carrier wave increases and becomes maximum when the amplitude of the modulating signal reaches at its maximum. Now the amplitude of the carrier wave starts decreasing with decrease in amplitude of the modulating signal. So it is clear from the image that the amplitude of the pulsed carrier wave varies according to the instantaneous value of the message signal. Important Observations- #As it is Pulse Amplitude Modulation (PAM), therefore only the amplitude of the pulsed carrier changes. There is no change in the width or position of the pulsed carrier wave. So the width and position of the carrier wave pulse is constant here. Therefore we can say that, all the information of the modulating signal is contained in the amplitude variations of the pulses. No information is present in the width or position of the pulses. Pulse Time Modulation (PTM) In pulse time modulation, the width or position of the pulsed carrier wave is varied (variations on the time axis) as per the changes in the amplitude of the modulating signal. As we have discussed already that Pulse time modulation is of two types- Pulse Width Modulation (PWM)/Pulse Duration Modulation (PDM) and Pulse Position Modulation (PPM) So first let's start with pulse width modulation. Pulse Width Modulation (PWM)/Pulse Duration Modulation (PDM) Definition:- In Pulse width modulation, width (duration) of the pulses of the carrier wave is varied according to the modulating signal (message signal). Now we will understand the waveform of pulse width modulation. Look at the image given below to see the waveform of pulse width modulated signal.

Pulse Amplitude Modulation (PAM) Fundamentals [HD]
 
24:46
this lecture explains- Basics of Pulse Amplitude Modulation (PAM) and PAM waveform. Modulation is a pulse modulation technique. Other techniques of analog pulse modulation are- Pulse Width Modulation (PWM) and Pulse Position Modulation (PPM). But before discussing pulse amplitude modulation, it is important to know, what is pulse modulation and how it is different from continuous wave modulation. In pulse modulation, some parameter (amplitude, width or position) of the pulsed carrier wave is varied as per the instantaneous value of the modulating signal (message signal). Types of analog pulse modulation techniques are- Pulse Amplitude Modulation (PAM), Pulse Width Modulation (PWM) and Pulse Position Modulation (PPM). While continuous wave modulation is a technique of modulation where some parameter (amplitude, frequency or phase) of a sinusoidal carrier is varied in accordance with the instantaneous value of the modulating signal. Types of continuous wave modulation are- Amplitude modulation (AM), Frequency Modulation (FM) and Phase Modulation (PM). See the image given below to understand different types of modulation techniques. The definitions of PAM, PWM and PPM are given below for quick reference- Pulse Amplitude Modulation (PAM) In pulse amplitude modulation, the amplitude of pulsed carrier wave is varied according to the modulating signal. Pulse Time Modulation (PTM) In pulse time modulation, the timing of pulses of the pulsed carrier is varied. Therefore the variations in the pulse are on the time axis. Pulse Time Modulation (PTM) is of two types- Pulse Width Modulation (PWM)/ Pulse Duration modulation (PDM) and Pulse Position Modulation (PPM) Pulse Width Modulation (PWM) In PWM, the width of pulsed carrier wave is varied as per the instantaneous value of the modulating signal. Pulse Position Modulation (PPM) In PPM, the position of pulsed carrier is varied as per the modulating signal (message signal). Now we understand the basic difference between PAM, PWM and PPM. Now it's time to discuss pulse Amplitude Modulation in some detail- Pulse Amplitude Modulation (PAM) Definition:- The modulation technique in which the instantaneous amplitude of the pulsed carrier is varied according to the modulating signal (message signal) is called as pulse amplitude modulation. Waveform of pulse amplitude modulation Look at the image given below carefully to understand the formation of pulse amplitude modulated wave. Here in this image, you can see, three waveforms. The first waveform is of modulating signal (message signal), the second one is of the pulsed career wave and the third waveform is of the pulse amplitude modulated wave (PAM).

Now look at the image shown above very carefully, observe that, as the amplitude of the modulating signal (message signal or baseband signal) increases, the amplitude of the pulsed carrier wave increases and becomes maximum when the amplitude of the modulating signal reaches at its maximum. Now the amplitude of the carrier wave starts decreasing with decrease in amplitude of the modulating signal. So it is clear from the image that the amplitude of the pulsed carrier wave varies according to the instantaneous value of the message signal. Important Observations (PAM) #As it is Pulse Amplitude Modulation (PAM), therefore only the amplitude of the pulsed carrier changes. #There is no change in the width or position of the pulsed carrier wave. So the width and position of the carrier wave pulse is constant here. #Therefore all the information of the modulating signal is contained in the amplitude variations of the pulses.

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.
