Title: TTF,小波变换 Download
 Description: Based on FFT harmonic detection, the frequency and amplitude characteristics of each harmonic component in the original waveform are obtained by using fast Fourier algorithm, from which the frequency and amplitude information of each harmonic component can be directly observed In program 1, the frequency and amplitude characteristics of each component in the original waveform are obtained by using the fast Fourier algorithm The spectrum characteristic diagram of program 2 input signal through FFT transformation Program 3 samples the input signal and applies one-dimensional wavelet transform function to three-level wavelet analysis
