Abstract
By studying of DFT, some interesting phenomena relating to special frequency of sinusoidal signal that are similar to the beat phenomenon in physical vibration theory are found. In this paper, the characteristics of its spectrogram are described in detail, and we have analyzed the reasons that cause this kind of phenomenon by the angle of phase difference.
