  • 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.
  • A repeater picks up the signal from the transmitter, then amplifies and retransmits it to the receiver sometimes with a change in carrier frequency.
  • Repeaters are used to extend the range of a communication system. Hence, option 3 is correct.
