摘要
研究了信号的奇异性检测问题.给出小波变换和信号奇异性的关系及小波基的选取方法,实现小波分析对信号各类奇异间断点的有效检测,最后进行实例分析,分析结果表明此理论与方法适用于对边缘信号与突变信号的处理和提取.
The problem on signal singularity detection is studied. The relation between wavelet transformation and signal singularity and the selecting method for wavelet am presented, and the wavelet analysis detects all kinds of singularity discontinuous point effectively. Example studies show that the wavelet transform technique and theory are applicable to processing and collecting the brim signal and the sudden signal.
