Abstract
A motion sensor includes an amplitude difference processor coupled to receive a first signal representative of a first one of a plurality of AGC control signals and a second signal representative of a second one of the plurality of AGC control signals. The amplitude difference processor is configured to detect if a value of the first signal is representative of a different gain than a value of the second signal by a predetermined amount. In response to the detection, the AGC processor is configured to change the value of the first one of the plurality of AGC control signals to bring its value closer to the value of the second one of the AGC control signals. A method and computer-readable storage medium can use the motion sensor.
