Patent number: 7741905Abstract: An automatic gain control circuit includes a first voltage dividing resistor, a filter circuit, a switch circuit, and an amplifying circuit. The first voltage dividing resistor divides a voltage of the automatic gain control circuit using an internal impedance of the audio device to produce a divided DC voltage, wherein the first voltage dividing resistor is connected between a first power source and an output of the audio device. The filter circuit filters audio signals outputted from the audio device to produce filtered audio signals, and wherein the filter circuit receives the divided DC voltage, wherein the filter circuit is connected to the output of the audio device. The switch circuit outputs controlling signals according to the divided DC voltage from the filter circuit.
