Signal processing method and device, electronic equipment and computer readable storage medium

The invention discloses a signal processing method and device, electronic equipment and a computer readable storage medium. The method comprises the steps that a first pulse signal and a second pulse signal are obtained, and the second pulse signal is a pulse signal with the frequency being the reference frequency; obtaining a difference signal based on the first pulse signal and the second pulse signal; the difference value signals are input into a first first-order low-pass filter, high-frequency signals and low-frequency signals are filtered out, the high-frequency signals are high-frequency-band signals in the difference value signals, and the low-frequency signals are low-frequency-band signals in the difference value signals; and determining a target signal according to the high-frequency signal and the low-frequency signal. According to the invention, the technical problem of inaccurate frequency calibration during frequency calibration in the prior art is solved. 本发明公开了一种信号处理方法、装置、电子设备及计算机可读存储介质。其中，该方
