【Abstract】 By using the wavelet transform to detect the singularity of several kinds of signal, some principle about choosing the wavelet basis and a detection algorithm are obtained. An example is given to prove their efficiency. They lay a theoretical foundation for the singularity detection of signal with the wavelet transform.更多还原
