  • Audio processing system
    Patent number: 8774427
    Abstract: The audio processing system disclosed in the invention comprises an audio processor and an audio amplifier. The audio processor receives a data signal to generate a processed signal, and comprises at least one gain control circuit and at least one operational amplifier. The gain control circuit generates a gain signal according to a volume control signal, a reference signal, and a feedback signal. The operational amplifier couples to the gain control circuit and amplifies the data signal by the gain signal to generate a processed signal. The audio amplifier couples to the audio processor to receive and amplify the processed signal, wherein an amplified signal is generated.
    Type: Grant
