Question

Advantages of source coding in digital communication

Answer 1

In source coding, the encoder maps the digital signal generated at the source output into another signal in digital form. The mapping is one to one and the objective is to eliminate or reduce the redundancy so as to provide an efficient representation of the source output. The source decoder simply performs the inverse mapping and thereby delivers to the user destination, a reproduction of the digital source output. The advantage of source coding is to reduce the bandwidth of transmission
