Claim 5:
6. A method for realizing self-adaptive adjustment and modulation of an audio signal of a Class D power amplifier, comprising:
(A) performing amplification processing, frequency detection processing and amplitude detection processing on the audio signal respectively;
(B) loading a signal generated after the frequency detection processing onto a carrier modulation signal, performing PWM processing on the signal generated after the frequency detection processing, the carrier modulation signal, and a signal generated after the amplification processing, performing system drive processing on a signal generated after the PWM processing, and combining a signal generated after the system drive processing and the audio signal; and
(C) performing DC potential adjustment processing on a signal generated after the amplitude detection processing to generate a DC potential of the audio signal.
