Transcribed Image Text:1. Two signals gl(t) and g2(t) are to be transmitted over a common channel by
means of ime division multiplexing. The highest freq of gl(t) is 1 KHz and that
g2(t) is 1.5 KHz. What is the minimum value of the permissible sampling rate?

2. 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 I us duration. The highest frequency
component of each voice signal is 3.4KHz.

a. Assuming a sampling rate of 8 KHz, Find the spacing between successive
pulses of the multiplexed signal.
b. Repeat your calculation assuming the use of nyquist rate sampling.
