Assertion: The process of retrieval of information from the carrier wave at the reciever is termed as modulation.
Reason: Repeater helps to modulate the signals.

Text Solution

Verified by Experts

The correct Answer is:
D
The process of retrieval of information from the carrier wave at the receiver is termed as demodulation. Repeater in a combination of a receiver and a transmitter. A repeater picks up the signal from the transmitter. Amplifier and retransmits it to the receiver sometimes with a change in carrier frequency.
