Automatic Gain Control (AGC) for Noise Cancellation

Automatic Gain Control (AGC) is a function that may also be provided by a Programmable Gain Amplifier (PGA) in an electronic circuit. This function dynamically adjusts gain, typically via a feedback signal, to shape the output signal to the desired amplitude in response to external conditions. AGC can be used to provide near real-time control and may also be referred to as adaptive control.
