By analyzing and calculating the transform process of several singularities on different singularity signals, the effect of wavelet transform in signal singularity verification is verified. The effects of several wavelet transforms are compared, and the singularity of signals such as step and triangular wave The basic selection rules of wavelet in sex testing.
