Function of repeater: A repeater is used to increase the range of the transmission in communication systems with the help of a set of receiver and transmitter. They are erected at suitable locations in between the transmitter and the receiver. Each repeater receives the transmitted signal, amplifies it properly keeping its original form intact and then relays it to the next repeater.
