features of signals, however, the frequency domain characteristics of signals are easily obtained through Fourier transformation.The simple and common understanding of Fourier transform is to combine seemingly chaotic signals into basic sine (Cosine) signals of a certain amplitude, phase, and frequency, the purpose of Fourier transformation is to find out the frequency corresponding to the large amplitude (High Energy) signals in these basic sine (Cosine) signals, so as to find out the main vib
