Abstract
A digital automatic gain control circuit for a receiver includes an averaging block and an adjustment block. The averaging block receives a length of a digital sample stream that represents an incoming analog signal and produces an absolute average signal. The adjustment block receives the absolute average signal and a reference signal and outputs an adjustment signal for controlling gain. The adjustment signal is based on a difference between the absolute average signal and the reference signal. In an alternative embodiment, a method of controlling gain according to the invention includes the steps of calculating an absolute average of an incoming signal, and comparing the absolute average to a reference to produce an adjustment signal based on a difference between the absolute average and the reference.
