In system design, what is the primary benefit provided by a repeater to users?

• A. To store emergency calls for later review
• B. To convert analog signals to digital
• C. To amplify the radio signal to extend coverage
• D. To provide a backup power source

Answer: (C)

A repeater’s main purpose in radio systems is to extend coverage by receiving a signal from a user and then retransmitting it at higher power (often on a separate channel), which helps overcome distance and terrain limitations. This boosts reliability and reach so users can communicate over a larger area, especially in challenging environments. It isn’t about storing emergency calls, converting analog to digital, or providing a backup power source—the repeater’s job is to amplify and relay the signal to broaden the usable range.
