4) A multiplexer uses TDM scheme for 15 different signals. Each signal is sampled by flat-top sampling with a sampling duration 2.5 μsec. During operation synchronization is provided by using additional 5 bits, each has 4.5 usec duration. a) If the sampling rate is 5kHz, what is the spacing between two channels? b) What should be the sampling rate, to be able to use 2 usec spacing? 4) A multiplexer uses TDM scheme for 15 different signals.

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