Step-by-step explanation:

An analog signal uses some property of the medium to convey the signal's information. For example, an aneroid barometer uses rotary position as the signal to convey pressure information. In an electrical signal, the voltage, current, or frequency of the signal may be varied to represent the information.

Analog signals are transmitted through electromagnetic waves that give a more accurate portrayal of physical phenomena like sound, light, temperature, position, and pressure.
