C_Diffraction

DDC的处理,描述从ADC采集数据后信号的下变频处理.主要是信号滤波和抽取(digital handle)

Matlab编程基础及应用，是学习matlab的好材料(Matlab programming basic and applied, is a good material to learn matlab)

ACTIVLEV Measure active speech levelin voice commands

Matlab入门学习，包括源程序，word文档已解密。(Matlab entry-learning, including source code, word documents decrypted.)

这个Matlab图形用户界面允许用户计算圆形，椭圆形和任意形状的广义极化张量。此计算的近似算法，该算法是基于Capdeboscq等人开发出一种方法。 (This Matlab GUI allows the user to compute the GPT of disks, ellipses, and arbitrary imported shapes. The approximating algorithm that does this computation is based off a method developed by Capdeboscq et al. )

数字信号处理matlab实现用书，适合入门的理想教材(Implementation of digital signal processing matlab book, the ideal textbook for entry)

数字信号处理在Matlab V4上的应用，纯英文书，是1997年的老书了，为PWS出版公司出版。与国内的薛年喜版《MATLAB在数字信号处理中的应用》不同，在matlab的入门上介绍不多，需要读者较熟悉matlab。(The Application of Digital Signal Processing in the Matlab V4,published by PWS publishing company in 1997.Compared with the Mr.Xue s version , there is an succinct introductory course in matlab,so that readers should know MATLAB well .)

小波包分解，提取能量特征，然后进行归一化处理，获取诊断信息(Wavelet Neural Network)

有限元的MATLAB程序，该MATLAB程序使用有限元法解决连续体的位移及受力问题。使用限制：节点处可受集中力，每一单元可受一个集中力，每边可受一常值边界力(Finite element MATLAB program, the problem of the MATLAB program using the finite element method to solve the continuum displacement and stress. Use restrictions: nodes under concentrated force, every unit can be subjected to a concentrated force, each side by a constant boundary force )

在PID控制中，微分信号的引入可改善系统的动态特性，但也易引起高频干扰。在误差扰动突变时尤其显出微分项的不足。若在控制算法中加入低通滤波器，则可使系统性能得到改善。(In PID control, the introduction of differential signal can improve the dynamic characteristics of the system, but it can also cause high-frequency interference. When error perturbations change abrupt, the deficiency of differential terms especially shows. If the low-pass filter is added to the control algorithm, the performance of the system can be improved.)
