Problem3:
Consider a time division multiplexing scheme with 14 users. Assuming each fh user has a message m;(t)
with a corresponding spectrum of M;(f) = ^ () and power P; = 2
7000,
(a) Determine the Nyquist sampling rate for m;(t)
(b) If the dynamic range for the i-th user varies between +3 and -3 volts determine the number of bits
per sample for a quantization SNR of 40DB
(c) If the sampling used is 1.2 times the Nyquist rate and in addition framing bits add an overhead of
4% what is the total data rate of the TDM system?
(d) If binary signaling is used what is minimum bandwidth required to transmit the TDM signal?
