AFC
n. uncountablen. Stands for Automatic Frequency Control. A system that automatically adjusts the volume or signal strength to keep it at a steady level. It helps prevent sounds from getting too loud or too quiet.
n. Abbreviation for Automatic Frequency Control. A circuit or software process that maintains a consistent output signal level by automatically adjusting the gain in response to input fluctuations. Often used in radio receivers and audio recording to prevent distortion.
The radio uses AFC to keep the volume steady.
Without AFC, the audio signal would clip and distort whenever the speaker raised their voice during the broadcast.
Engineers implemented a sophisticated AFC algorithm to ensure that the wireless transmission remained stable despite the interference caused by the surrounding steel structures.
