(b). Twenty-four voice signals are sampled uniformly and then time-division multiplexed. The sampling operation uses flat-top samples with lus duration. The multiplexing operation includes provision for synchronization by adding an extra pulse of sufficient amplitude and also 1 us duration. The highest frequency component of each voice signal is 3.4 kHz. (b.1) Assuming a sampling rate of 8 kHz, determine the spacing between successive pulses of the multiplexed signal. (b.2) Repeat your calculation assuming the use of Nyquist rate sampling.
