Q1. A multilevel digital communication system is to operate at a baud rate of 20Kbaud/s. Each
level is encoded as an 8 bit digital word for the multi level transmission. The message signal to be
transmitted is an analog signal which is PCM encoded with an 8 level quantizer.
a. What would be the minimum required bandwidth for the multi level transmission?
b. What would be the sampling rate of the PCM system ?
c. What would be the data rate of the system.
