Question 2:

In a digital transmission system, binary data are transmitted by rate 36 Mb/s utilizing M-ary PAM signal. Transmitted signal is a band-limited raised cosine signal, whose specifications are shown in Figure 2.

a) Determine the value of M and roll-off factor.

b) Assume that Signals are transmitted over a band-limited AWGN channel. What is the minimum value of Eb/N0 and SR based on probability of a bit error less than 10-6 and N0=10-17 W/Hz?
