Draw the block diagram of PCM receiver with the help of relevant wave form and explain its working
Block diagram of PCM receiver:-
Explanation:- A PCM signal contaminated with noise is available at the receive input. The regeneration circuit at the receiver will separate PCM pulses from noise and will reconstruct original PCM signal. The pulse generator has to operate in synchronization with that at transmitter. Cleaned PCM is fed to a serial to parallel converter. Then applied to a decoder which converts each code word into corresponding quantized sample value. This quantized PAM signal is passed through a low pass filter recovers the analog signal x (t).
