摘要
讨论了小波变换及其基本性质 ,探讨了基于小波变换模最大值沿尺度演变的信号突变检测的基本原理与方法。在不同尺度上分析和处理信号的各种频率成分 ,使信号的奇点、突变点被放大 。
Wavelet transform and its basic properties are described in the paper The principle of signal break detection based on variation of the wavelet transform modulus maximum along the scale is discussed, and method for signal break detection is presented A variety of frequency components is analyzed and processed at various scales The odd and break points of signals are amplified and become the means of diagnosing irregular signals
