Answer 1

Answer:

Modulation is a process through which audio, video, image or text information is added to an electrical or optical carrier signal to be transmitted over a telecommunication or electronic medium.

The primary purpose of modulation in a communication system is to generate a modulated signal suited to the characteristics of a transmission channel. In radio communications, modulation is needed in the transmission systems to transfer the message into the available high frequency radio channel.
