Problem one Twenty-four voice signals are sampled uniformly and then time-division multiplexed. The sampling operation uses flat-top samples with us duration. The multiplexing operation includes provision for synchronization by adding an extra pulse of sufficient amplitude and also s 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.

Problem one
Twenty-four voice signals are sampled uniformly and then time-division multiplexed. The
sampling operation uses flat-top samples with us duration. The multiplexing operation
includes provision for synchronization by adding an extra pulse of sufficient amplitude
and also us 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.
