讲述了现在机械故障诊断中用到的常用时频分析方法，如短时fft 魏格纳维尔分布 小波变换 HHT等，里面含有例子和详细说明，对初学者帮助很大。(Tells the now commonly used in mechanical fault diagnosis frequency analysis methods, such as short-time wavelet transform fft Wigner distribution HHT Louisville, etc., which contains examples and detailed instructions, very helpful for beginners.)

说明：  数字信号处理中，分别用重叠相加法和重叠保留法求两个序列的线性卷积，并对两种方法的结果进行比较。两种方法的结果是相同的。(Digital signal processing, respectively, and overlap with the overlap-add method to retain Method linear convolution of two sequences, and the two methods were compared. Two results are the same.)

随机生成十个数，和为1。使用c++语言，在vs2008上运行(Ten randomly generated number, and to 1. Using c++ language, running on vs2008)

ga算法 优化PID参数 功能简单实用 很好很强大(the right thing)

在训练序列方法中，介绍了时域结构不同的三种算法，比较了它 们的估计性能。在循环前缀算法这一节中，提出了一种基于循环前缀的改进算法，(No Ordinary Blanket This is my blanket. My blanket is not just an ordinary blanket. My blanket can change into different things. If I tie it around my neck, my blanket can change into a cape. “I am Superman!” If I drape it between two chairs, my blanket can change into a fort. “I am the captain of my fort!” If I put it over my head, my blanket can change into a ghost)

给学习emd的一个文献，文献写的相当好。(Emd to learn a literature, literature written quite well.)

关于如何使用matlab的书籍，应用MATLAB语言处理数字信号与数字图像。(Books on how to use matlab MATLAB language processing digital signals and digital images.)
