A PAM telemetry system involves the multiplexing of four input signals: s;(t), i = 1, 2, 3, 4. Two of the signals s1(t) and s2(t) have bandwidths of 80 Hz each, whereas the remaining two signals s3(t) and s4(t) have bandwidths of 1 kHz each. The signals s3(t) and s4(t) are each sam- pled at the rate of 2400 samples per second. This sampling rate is divided by 2* (i.e., an inte- ger power of 2) in order to derive the sampling rate for s1(t) and s2(t). (a) Find the maximum value of R. (b) Using the value of R found in part (a), design a multiplexing system that first multiplexes s1(t) and s2(t) into a new sequence, s5(t), and then multiplexes s3(t), s4(t), and s5(t).
