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:
