Abstract:
An automatic gain control apparatus includes an amplitude detecting circuit, a distortion detecting circuit, a gain determining circuit and an amplifying circuit. The amplifying circuit applies a gain to an input signal to generate an output signal. The amplitude detecting circuit detects an average amplitude of the input signal. The distortion detecting circuit detects a distortion level of the output signal. The gain determining circuit determines the gain used by the amplifying circuit according to the average amplitude and the distortion level.

Claim (Index 7):
An automatic gain control method, comprising:\n a) applying a gain to an input signal to generate an output signal; b) detecting an average amplitude of the input signal; c) detecting a distortion level of the output signal; d) generating an adjusted gain according to the average amplitude and the distortion level; and e) applying the adjusted gain to the input signal, wherein step (c) comprises: comparing an absolute value of an amplitude of the output signal with an amplitude threshold; increasing a counting result by one each time the absolute value of the amplitude of the output signal is higher than the amplitude threshold during a predetermined period; and outputting the counting result as the distortion level as the predetermined period ends.
