摘要
Abstract
The singularity of signal is an important character of signal. Form the singularity,the interrupted point or discontinuous point can be gained. The wavelet transformation is an effective tool in the singularity detection. By using different wavelet transformation, the effect of wavelet transformation is validated in finding singularity's location. Based on the compare of the results and the Lip index, the rule of wavelet selection in step or triangular signal detection is proposed.关键词
