Explanation:
Detailed explanation-1: -Both analog and digital radios send signals over a radio channel using a Very High Frequency (VHF) or Ultra High Frequency (UHF) carrier frequency wave. In simple terms, analog radios use frequency modulation (FM) to encode a voice signal within a carrier wave.
Detailed explanation-2: -Radio, whether satellite or over the air, is transmitted as a signal that is interpreted by your device. If you’re listening to satellite radio, the signal is digital, but if you’re listening to broadcast or “over the air” radio the signal is analog.
