滚动轴承外圈故障频率，小波分析后包络变换，数据来源西储大学

Rice大学的ricewavelet小波变换工具包，用于matlab环境下，内含图像处理所需的几乎所有小波变换功能，很好很强大(failed to translate)

本代码是小波包学习和使用的初学代码，简单改造可对信号进行滤波，去噪，实现我们需要的各种功能(xiaobobao )

实现f-k变换，功能强大，各种滤波处理，地震波等都能用(wavelet transformF -k transform, powerful, a variety of filtering, seismic waves can be used)

小波分析程序，包括墨西哥小波morlet小波(Wavelet analysis program)

一个利用小波变换模极大值方法进行信号检测的程序(a wavelet transform modulus maxima method of signal detection procedures)

说明：  多小波代码，有CL,GHM,Sa4,Opt-rec四种多小波的变换与反变化，前处理和后处理的代码。(Multiwavelet code, there are CL, GHM, Sa4, Opt-rec four Multiwavelet Transform and anti-change, pre-treatment and post-processing code.)

基于小波变换的异步电机的故障诊断，本文采用三层小波包分析，诊断效果较好(Wavelet-based fault diagnosis of induction motors, this paper, three wavelet packet analysis, diagnosis, better)

一维小波单支重构函数，一维小波系数直接重构函数(Single one-dimensional reconstruction of wavelet functions, the direct reconstruction of one-dimensional wavelet function)

该程序主要是通过小波变换来实现对心音信号的去噪处理(The program is mainly achieved by wavelet denoising of heart sound signals)
