AGC
Transmitters and Receivers Glossary
Information on AGC
The strength of the wanted signal will fluctuate because of changes in propagation conditions. A receiver therefore includes automatic gain control to maintain the signal at the input to the detector at a constant value despite fluctuations in the signal strength at the antenna. AGC ensures that the operator hears a reasonably constant volume as the propagation conditions change, or as the receiver is tuned from one station to another.
