一种基于DWT小波变换的数字音频水印嵌入方法，供大家参考学习(Based on the the DWT wavelet transform digital audio watermark embedding method for your reference learning)

说明：  关于小波变换的ppt，有用的可以下载看看(Ppt on Wavelet Transform)

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

此代码是用在被成为数学魔法师的MAPLE软件上运行的。此代码清晰的描述了欧拉公式的图象变换。以及如何在MAPLE里解欧拉公式。(This code is used in the magician to become the MAPLE mathematical software running. This code describes a clear image transform Euler formula. And how to MAPLE Euler formula in solution.)

心电信号的预处理。高通滤波器，低通滤波器，50Hz带阻滤波器。(The preprocessing of the ECG signal. High-pass filter, low pass filter, 50Hz band-stop filter....)

MATLAB中文论坛Simulink控制系统板块发表的帖子:移相全桥DC/DC变换器仿真报错。 只需一步,快速开始 扫一扫,访问微社区 MATLAB中文论坛(Altar Simulink physics modeling board posted post: isolated two-way full bridge DCDC Resonant Converter... My simulation has been possible, the transformer has some problems, PWM correct phase shift generator, I have)

此程序仿真了一个被污染了的信号源，然后通过小波去噪，成功取出了信号中的杂波(This procedure simulation has polluted the supply oscillator, then through the wavelet denoising, the success took out in the signal clutter )

this watermarking is implemented using wavelet transform..

利用小波包分析信号的matlab程序，大家可以参考(Matlab program using wavelet packet analysis of the signal, we can refer to)

这是一款用来分析心率变异性的matlab程序，有线性分析和非线性分析，包含输出结果包含频谱分布、统计学描述、样本熵、小波分析(This is a matlab program used to analyze heart rate variability, linear analysis and nonlinear analysis contains the output contains spectral distribution, statistical description sample entropy, wavelet analysis)
