Abstract:
An embodiment is a method and apparatus to process an input signal. An analog automatic gain control (AGC) processor controls an analog adjustable gain of the input signal using a feedback mechanism. The analog AGC processor generates a first signal. A processing circuit transforms the first signal into a second signal. A digital AGC processor controls a digital adjustable gain of the second signal using a feed-forward mechanism.
