| 摘 要： | 由于谐波小波具有良好的盒形频谱特性,应用谐波小波可以将非平稳振动信号既不交叠又无遗漏地分解到相互独立的频带上去,特定频段的成分与信号的其它频率成分通过谐波小波分解被分离了,再进行重构就可将特定频段的成分提取出来,实现谐波小波滤波.

| Abstract: | Harmonic wavelet has a fine refinement function, which could decompose non-stationery data to independent frequency bands without any overlopping or leak. The characteristic frequent components and other components are decomposed through harmonic wavelet analysis. Then the characteristic frequency component will be abstracted by the recompose of data, which is designated as harmonic wavelet filter. |
