Question

2.3. We wish to transmit a 100-character alphanumeric message in 2 s, using 7-bit ASCII coding, followed by an eighth bit for error detection, per character, as in Problem 2.1. A multilevel PAM waveform with M-32 levels is used. (a) Calculate the effective transmitted bit rate and the symbol rate. (b) Repeat part (a) for 16-level PAM, eight-level PAM, four-level PAM, and PCM (binary) waveforms.
