Twenty Four Voice Signals Are Sampled Uniformly And Then

Twenty-four voice signals are sampled uniformly and then rime-division multiplexed. The sampling operation uses flat-top samples with 1 μ duration. The multiplexing operation includes provision for synchronization by adding an extra pulse of sufficient amplitude and also 1 μ duration. The highest frequency component of each voice signal is 3.4 kHz.

(a) Assuming a sampling rate of 8 kHz, calculate the spacing between successive pulses of the multiplexed signal.

(b) Repeat your calculation assuming the use of Nyquist rate sampling.
