BF961 datasheet
Automatic Gain Control - AGC
Automatic Gain Control or AGC is a circuit design which maintain the same level of amplification for sound or radio frequency. If the signal is too low the AGC circuit will increase ( amplify ) the level and if is to high will lower it to maintain a constant level as possible.
The Automatic Gain Control [...]
