Question: Twenty four voice signals are sampled uniformly and then time division multiplexed. the sampling operation uses flat top samples with 1-us duration. the multiplexing operation includes provision for synchronization by adding an extra pulse of appropriate amplitude and 1-us duration. the highiest frequency component of each voice signal is 3.4Khz . a) assuming sampling rate of 8khz, calculate the spacing between sucessive pulses of the multiplexed signal.
