AUDIO PROCESSING CHIP AND AUDIO SIGNAL PROCESSING METHOD THEREOF |
摘要 |
An audio processing chip includes a connecting port, an audio amplifier module and a pulse width modulation (PWM) control circuit. The connecting port receives a pulse width modulation (PWM) signal; the audio amplifier module amplifies an audio signal according to a control signal to thereby output an audio output signal; and the pulse width modulation (PWM) control circuit is coupled between the connecting port and the audio amplifier module, and outputs the control signal to the audio amplifier module according to the PWM signal to thereby control an operation of the audio amplifier module.
