- It is a combination of transmitter, amplifier, and receiver.
- The receiver receives the signal, which is then amplified using the amplifier. This amplified signal is then transmitted using a transmitter.
- A number of repeaters are used in the transmission medium to increase the range of communication. A signal during transmission gets attenuated so repeaters are necessary for effective communication.
- A communication satellite is essentially a repeater station in space.
EXPLANATION:
- A repeater is a combination of a receiver and a transmitter. Hence, option 3 is correct.
- A repeater picks up the signal from the transmitter, then amplifies and retransmits it to the receiver sometimes with a change in carrier frequency
