Patent ID: 8116485

Claim:
An automatic gain control method executed by a gain control system, comprising determining whether an input signal level of an input signal comprising desired signal content and undesired signal content exceeds a processing bound on signal levels for subsequent signal processing; attenuating the input signal when the input signal level of the input signal exceeds the processing bound to provide an output signal; determining a desired signal content level of the desired signal content in the input signal and an undesired signal content level of the undesired signal content in the input signal; determining whether the desired signal content level of the desired signal content in the input signal caused the input signal level to exceed the processing bound; compensating the output signal for the of the desired signal content in the input signal when the desired signal content level of the desired signal content in the input signal did not cause the input signal level to exceed the processing bound, where the compensating of the output signal is controlled such that an output signal level of the output signal does not exceed the processing bound; and forgoing compensation of the output signal for the attenuation of the input signal when the desired signal content level caused the input signal level to exceed the processing bound.
