उत्तर

A basic communication system consists of BADEC.

Explanation:

A basic communication system consists of an information source, a transmitter, a link (channel) and a receiver or a communication system is a set-up used in the transmission and reception of information from one place to another.

The whole system consists of several elements in a sequence. It can be represented in the diagram given below:
