------An analog signal is sampled, quantized, and encoded into a binary PCM wave. The number of representation levels used is 1024. A synchronizing pulse is added at the end of each code word representing a sample of the analog signal. The resulting PCM wave is transmitted over a channel of bandwidth 24kHz using a 8 PAM system with raised-cosine spectrum. The rolloff factor is 0.5.

(a) Find the rate (bit/s) at which information is transmitted through the channel.

(b) Find the rate at which the analog signal is sampled. What is the maximum possible value for the highest frequency component of the analog signal?

is using a 8 PAM system is different from using a quaternary PAM in this example ?????

thanks
