------An analog signal is sampled, quantized, and encoded into abinary PCM wave. The number of representation levels used is 1024.A synchronizing pulse is added at the end of each code wordrepresenting a sample of the analog signal. The resulting PCM waveis transmitted over a channel of bandwidth 24kHz using a 8PAM system with raised-cosine spectrum. The rolloff factoris 0.5.
(a) Find the rate (bit/s) at which information is transmittedthrough the channel.
(b) Find the rate at which the analog signal is sampled. What isthe maximum possible value for the highest frequency component ofthe analog signal?
is using a 8 PAM system is different from usinga quaternary PAM in this example ?????
thanks
