This paper expounded the principle of using Fast Fourier transform measuring the phase difference and completed the simulation of measuring the phase differences of a plurality of signal. The simulation results show that the method can rapidly and accurately realize the phase difference measurement without considering the AD quantization error and noise interference. In considering the AD quantization error and random noise, Fast Fourier transform measuring the phase difference still has high measurement accuracy, and the measurement error can be controlled within 0.01°. The method can be applied in practical engineering.
