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: 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 0 and smaller than a first threshold, each of the positive output signal and the negative output signal includes 2 pulses within one pulse period, and pulse widths of the pulses included in the positive output signal are different from pulse widths of the pulses included in the negative output signal. This solution can reduce the frequency requirements for a passive filter that processes positive and negative output signals, thereby reducing the costs of the system for signal processing.
