Abstract
Embodiments of the present disclosure provide a method for signal processing, a circuit for signal processing, a chip for signal processing, and an electronic device. The method for signal processing includes: performing PWM modulation on an input signal to obtain a PWM positive signal and a PWM negative signal; and outputting a positive output signal and a negative output signal based on the PWM positive signal and the PWM negative signal; wherein, in response to an absolute value of an amplitude of the input signal being larger than a threshold, one output signal of the positive output signal and the negative output signal does not include a pulse, and the other output signal of the positive output signal and the negative output signal includes 2 pulses within one pulse period. This solution can improve the performance of the output signal while improving the performance.
