Question

Design a TDM system to handle 3 PAM channels if the maximum input frequency of each channel is 5 kHz

Answer 1

According to question,

TDM system is handling the number of PAM(N)=3

Maximum input frequency of each signal (w)=5 kHz

We know that if N channel of time division multiplexed then minimum transmission bandwidth 

$B_ T ​ =NW\\ B_T=3\times 5kHz =15kHz$
