Abstract
An automatic gain control (AGC) system includes at least one variable-gain component having a controllable gain over a gain control range and a sensor for sensing an amplitude of a signal from the at least one variable-gain control component. The sensor may have an operating window based upon the signal that is smaller than the gain control range of the at least one variable-gain component. The AGC system may also include a controller responsive to the sensor for controlling the at least one variable-gain component according to coarse and fine gain values to set the amplitude of the signal within the operating window of the sensor. The controller may implement at least one coarse gain jump from a current coarse gain value to a new coarse gain value when the sensor indicates the amplitude is outside the operating window. The controller may further implement movement to a fine gain value when the sensor indicates the amplitude is in the operating window.
