说明：  OCC变换，这是一个单周期控制模块，用于PWM的整流控制(Coordinate transformation)

语音信号处理综合运用了数字信号处理的理论知识，对信号进行计算及频谱 分析，设计滤波器，并对含噪信号进行滤波 (Speech signal processing of digital signal processing integrated use of theoretical knowledge, to calculate the signal and spectrum analysis, design filter, and filter the noisy signal)

小波阈值收缩算法的matlab程序，对信号进行去噪得到纯净语音(Wavelet threshold shrinkage algorithms matlab program, get on the clean speech signal denoising)

vc调用matlab引擎的，图文并茂的介绍操作步骤，并给出简单的调用程序(vc call matlab engine, illustrated introduction to the steps, and gives a simple procedure call)

使用matlab解决插值问题，包括 Lagrange 插值，分段线性插值，三次样条插值(Using matlab to solve the interpolation problem, including though laser interpolation, piecewise linear interpolation, cubic spline interpolation )

matlab画图的英文说明，有点小用处，没时间翻译，请见谅(how to plot pretty figure in matlab)

数字信号处理中的时域抽样定理，作为初学者自己编写的，绝对正确，有详细的推导(Digital signal processing in the time domain sampling theorem, as a beginner I have written, absolutely right, there is a detailed derivation)

本文件包括matlab 仿真内容 有 四阶龙库格 函数仿真 等(This document contains the contents of matlab simulation of fourth-order function of simulation cell Long Library)

将含有高斯白噪声的输入信号通过线性系统后（带阻滤波器）的输入、输出前信号的频谱、功率谱对比。同时给出了线性系统特性(Gaussian white noise, containing the input signal by a linear system (bandstop filter) of the input, before the output signal spectrum, the power spectrum of contrast. Also gives a linear system characteristics)

this file is an ac to ac controller. you can control the output by adjusting the firing angle of the SCR.
