Two low pass signals, each band limited 4 KHz, are to be time multiplexed into a single channel using PAM. Each signal is impulse sampled at a rate 10 KHz. The time multiplexed signal waveform is filtered by an ideal LPF before transmission. (a) What is minimum clock frequency of the system? (b) What is the minimum cut off frequency of the LPF? Ans.(a) 20KHz (b) 10KHz
