Classification: CPC H  G | IPC H

Claim 8:
9. The class-D amplifying system of claim 8, wherein the output signal includes a signal pair including a positive sub-signal and a negative sub-signal and the PWM signal includes a signal pair including a positive sub-signal and a negative sub-signal, and wherein in the adaptive voltage position mode and in a rapid response mode, in a case when the state (C) is in presence, when a level state of the positive sub-signal of the output signal is different from a level state of the positive sub-signal of the PWM signal and/or when a level state of the negative sub-signal of the output signal is different from a level state of the negative sub-signal of the PWM signal, the CM adjustment current is further positively correlated with a product of a predetermined voltage difference multiplied by a predetermined coefficient.
