carrier signal
Modulated wave base
A carrier signal is a steady waveform—typically a radio frequency—that gets modified to transmit information.
The signal itself carries no message; it serves as a vehicle for data imposed through modulation.
AM radio modulates the carrier's amplitude; FM modulates its frequency.
The carrier signal was strong, but the audio quality was poor.
