The circuit used to regenerate clock pulses from the transmitted PAM s

1.	The circuit used to regenerate clock pulses from the transmitted PAM signals is called ____(a) Clock demodulator circuits(b) Timer circuits(c) Clock receiving circuits(d) Clock recovery circuitsI got this question in examination.This is a very interesting question from Time Division Multiplexing topic in section Radio Transmitters, Communication Receivers, Multiplexing and Demultiplexing of Avionics
Answer» Correct option is (d) Clock recovery circuits Easiest explanation: INSTEAD of using a free-running clock oscillator set to the identical FREQUENCY of the TRANSMITTER system clock, the clock for the demultiplexer is derived from the received PAM signal itself. A circuit called the clock recovery circuits are TYPICAL of those used to generate the demultiplexer clock pulses.
