You are designing multi band UHF police radio and VHF fire radio systems for a municipal office. Because of the closeness of the transmit and receive frequencies, you must ensure there is adequate filtering and gain control of the systems. Which device will best meet the ability to separate and control the transmit and receive signals?

Question

Quizplus · Accepted Answer

A repeater is the best choice for separating and controlling the transmit and receive signals. It receives a weak or low-level signal, amplifies it, and re-transmits it at a higher level or power to the other end of the communication circuit. It has separate antennas for the transmit and receive signals, filters for controlling interference and noise, and gain controls for regulating the signal strength. This allows the repeater to effectively separate the transmit and receive frequencies and ensure clear and reliable communication.
