Q15/ Channel 1 of Six channels PAM system handles 1KHZ signal. Channel 2 handles 2 KHz signals, channel 3 handles 3 KHz, channel 4 handles 6 KHz and channel 5 handles 6 KHz and channel 6 handles 25 KHz. The six channels are sampled at equal intervals of time using very narrow pulses at the lowest frequency that is theoretical adequate. The sampled signals are time multiplexed and passed through a LPF before transmission. a. What is the minimum clock frequency of the PAM system? b. Find Tx and Bx? c. What is the minimum cut off frequency of LPF used before transmission that will preserve the amplitude information on the output pulses? d. What would be the minimum bandwidth if these channels were frequency multiplexed, using AM technique and SSB technique?
