carrier wave
Modulated transmission base
A carrier wave is a radio wave of constant frequency that can be modulated to transmit a signal.
The wave itself carries no information—it serves as a vehicle for the actual content, which is imposed on it by varying its amplitude, frequency, or phase.
AM and FM radio work by modulating carrier waves in different ways.
