Detailed explanation-1: -At its base, an analog signal is a continuous signal in which one time-varying quantity (such as voltage, pressure, etc.) represents another time-based variable. In other words, one variable is an analog of the other.

Detailed explanation-2: -U.S. radio broadcasters are now simultaneously broadcasting both traditional analog signals and digital signals that can be picked up with a digital radio receiver. The digital signals offer better sound quality than analog, and, unlike satellite radio services, are free-of-charge. What is digital radio?

Detailed explanation-3: -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-4: -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.
