Multilevel data with an equivalent bit rate of 2,400 bits/s is sent over a channel using a four-level line code that has a rectangular pulse shape at the output of the transmitter. The overall transmission system (i.e., the transmitter, channel, and receiver) has an r = 0.5 raised cosine-rolloff Nyquist filter characteristics
(a) Find the baud rate of the received signal.
(b) Find the 6-dB bandwidth for this transmission system.
(c) Find the absolute bandwidth for the system.
