Question

Quizplus · Accepted Answer

Automatic gain control (AGC) is a feature used to prevent sudden changes in volume by automatically adjusting the gain (amplification) of an audio signal. It ensures that the output from the receiver remains at a constant level, regardless of fluctuations in the input signal. This is a commonly used feature in modern audio equipment, and helps prevent annoying volume changes that can be distracting or even damaging to speakers. The other options (A, C, and D) are not relevant to the prevention of volume changes.
