The article presents quick method of wavelet decomposing and reconstruction based on basic conception and theroy of wavelet transform. The principle of singularity detection in signals and technique of time-frequency analysis with wavelet transform are introduced in details in this paper. The technique of how to detect the singularity of signals with wavelet transform is also illustrated with a example.
