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?

Consider a 1Mbps transmission channel. The clock at the receiver has a drift of 1 second in one year. How long asequence of bits (or frame) can be sent before the clock drift could cause a problem? Assume that the sender and receiver are synchronized at the beginning of each frame and that they cannot resynchronize during the frame. Also, assume that the receiver samples the received signal at the middle of each bit duration to detect if it is 0 or 1.
