Signal power factor acquisition method and device, processor and electronic equipment

The invention discloses a signal power factor acquisition method and device, a processor and electronic equipment. The method is applied to a processor and comprises the following steps: a first reference signal and a second reference signal are obtained, wherein the first reference signal and the second reference signal are digital signals and are the same as a target signal of a to-be-detected digital signal in signal frequency, and there is a phase difference between the first reference signal and the second reference signal; the first reference signal is multiplied by the target signal toobtain a first output signal; the second reference signal is multiplied by the target signal to obtain a second output signal; an in-phase component in the first output signal and a quadrature component in the second output signal are obtained; and the power factor of the target signal is obtained according to the in-phase component and the quadrature component. 本申请公开了一种信号的功率因数获取方法、装置、处理器及电子设备，方法应用于处理器，所述方法包括：获得第一参考信号和第二参
