Question

State whether given statement is True or False
A device which receives and then transmits electromagnetic signal in an artificial satellite is called transponder.

• A. True
• B. False

Answer 1

The correct option is A True

Answer is A.

A transponder is an electronic device used to wirelessly receive and transmit electrical signals. Fittingly, its name is equally derived from the words transmitter and responder. This device functions by receiving a signal, called an interrogator because it is effectively asking for information, then automatically conveying a radio wave at a predetermined frequency. In order to broadcast a signal on a different frequency than the one received, a frequency converter is built in. By receiving and transmitting on different frequencies, the two signals can be detected simultaneously.
Hence, the statement is true.
