Question

What is the role of the transmitter in the communication system?

(a) to decode a signal to be transmitted

(b) to convert one form of energy into other

(c) to detect and amplify information signal from the carrier

(d) to produce radio waves to transmit data

I had been asked this question by my college director while I was bunking the class.

This question is from Transmitter topic in division Elements of Communication System of Analog Communications

Answer 1

The correct choice is (d) to produce radio waves to transmit data

For explanation I would say: Transmitter is used to produce radio waves which are then sent to the antennae to transmitted. It encodes or modulates the message signal before transmission. Transducer converts a signal from one form of energy to other. Receiver detects and amplifies information signal from the carrier.
