Pulse Amplitude Modulation (PAM) is defined as the data transmission by altering the amplitudes of every pulse in a regular time sequence of electromagnetic pulses. Learn its circuit and block diagram at BYJU'S.
The basic type of pulse modulation is known as PAM or Pulse amplitude modulation, where the signal can be sampled at regular intervals & every sample can be made relative to the modulating signal’s amplitude on the sampling moment. The above block diagram of PAM shows the PAM signal generati...
we are using a PAM sampler that is Pulse Amplitude Modulation Sampler which converts continuous amplitude signal into Discrete-time- continuous signal (PAM pulses). The basic block diagram of PCM is given below for better understanding.
The block diagram of the pulse amplitude modulation (PAM) generator is shown in this figure. A low pass filter (LPF), a modulator, a pulse reshaping circuit (PRC), and the pulse generator are the main components of the PAM generator. ...

ThePulse Width Modulationis a technique in which the ON time or OFF time of a pulse is varied according to the amplitude of the modulating signal, keeping t Fig. 1: Block Diagram of Pulse Width Modulation (PWM) he (ON time + OFF time) time of the pulse as constant. The (ON time ...
Time-division multiplexing can be applied in instances where the messages are represented in pulse modulation format. Figure 2 illustrates such a scheme, where pulse amplitude modulation is used to represent the messages m1(t), m2(t),…, mn(t), which are now assumed to all be of bandwidth...
An amplitude modulated optical communication system and method are disclosed that achieve bandwidth compression by making use of an n level amplitude modulation scheme in
Pulse width modulation is the method used to control this switching transistor, the on and off time of which is controlled as a function of the output voltage (see figure 5.1). Figure 5.1: Schematic diagram of a pulse width modulator The output voltage Vout which is to be regulated is ...
