Digital Communication Pcm Block Diagram. Following is the block diagram of pcm which represents the basic elements of both the transmitter and the receiver sections. In sampling we are using pam sampler that is pulse amplitude modulation sampler which converts continuous amplitude signal into discrete time continuous signal pam pulses.
The signals in pcm are binary. The simplest form of pulse digital modulation is called pulse code modulation pcm. Low pass filter this filter eliminates the high frequency components present in the input analog signal which is greater than the highest frequency of the message signal to avoid aliasing of the message signal.
Pcm transmitter in pcm transmitter the signal x t is first passed through the low pass filter of cut off frequency f m hz.

Following is the block diagram of pcm which represents the basic elements of both the transmitter and the receiver sections. Digital transmission is the transmitted of digital pulses between two or more points in a communication system.
