Differentiate between Baud rate and Bandwidth. Also give their differences.

The bandwidth of a digital signal is the number of bits transmitted per second. The baud rate is the number of signalling elements transmitted per second.

In simple systems each signalling element encodes one bit, so the two values are the same. In more complex systems, the number of bits encoded per signalling element may be greater than one, so the bandwidth will be some multiple of the baud rate.
