说明：  此程序通过采样产生了一个非常标准的BPSK信号，是理解通信原理数字调制的好帮手(his procedure generated by sampling a very standard BPSK signal, digital modulation is to understand the principles of good communication assistant)

阶次分析的程序包，用于非平稳信号的特征提取。(Order Analysis package for non-stationary signal feature extraction.)

说明：  带延时的微分方程，这是matlab的四个源程序。(with the delay differential equations, which is the four Matlab source.)

该程序是专门对于电力电子晶闸管的过零触发设计。(this project is for Zero Trigger in the electrical.)

本人自编的一个快速作图，功能强大的matlab GUI 界面程序。其主要功能如下： 1.导入工作空间变量(X,Y)：导入工作空间变量，并提取类型为数组的变量。 2.绘图(plot)：多种模式，包括1对1，1对多，多对多。如x1—y1 x1—y1,y2；x1,x2—y1,y2。 3.快速标准化图形(NormalFig)：快速设置图形格式，以达到论文图片要求。字体大小，线型粗细等 4.可以手动设置格式 5.可以设置为笛卡尔坐标，也可以设置为对数坐标 6.右键执行命令:“Execute”旁的可编辑框，输入命令，右键执行。右键执行的好处是：可以保存变量到工作空间，实现非连续执行命令。 7.符号函数简易绘图(Ezplot)：快速绘制函数图，并可设置区间，区间设置用“ ”隔开。 8.锁定(lock)：锁定，即图形绘制在GUI坐标轴内；解锁，新建Fig，绘制图形，方便输出 9.保持和编辑(Hold,EditPlot)，编译后exe,亦可对图形进行拾取设置 另还有对变量转置等功能。 整个程序中，如操作失误，每处错误都有提示。 (It is a matlab program,which can help you plot beautiful figures easily,or make you learn some programming skills. In a word,it is a useful program and tool.)

战胜MATLAB必做练习50题，帮助你学会matlab(MATLAB exercises will be done over 50 questions to help you learn matlab)

毕业设计的代码，如果你也为此恼火的话，可以看一下。(Graduate design code, if you do this annoyed, you can look at.)

网上找来的共享的资源，结合matlab和C对图像进行灰度形态学的变换，为进一步的处理做准备。(Online recruited to shared resources, combined with matlab and C of the image gray-scale morphology of the transformation, in preparation for further processing.)

1.录制一段自己的语音信号,对录制的信号进行采样 画出采样后语音信号的时域波形和频谱图 给定滤波器的性能指标,采matlab设计数字滤波器,并画出滤波器的频率响应 然后用自己设计的滤波器对采集的信号进行滤波,画出滤波后信号的时域波形和频谱,并对滤波前后的信号进行对比,分析信号的变化 回放语音信号。2.(1. Recorded his voice for some signal, the signal is sampled on the record draw sampled speech signal time-domain waveform and frequency spectrum performance for a given filter, mining matlab digital filter design, and draw the filter frequency response then use their own filters designed to filter the collected signals, to draw the filtered time domain waveform and frequency spectrum, and comparing the signal before and after filtering, analysis of signal changes playback of audio signals. 2.)

一、观察序列频谱，观察信号通过系统后波形与频谱的变化。 系统函数，根据正准型结构（canonical form）编写样本处理算法。 (First, observe the sequence of the spectrum, observing the signal waveform and frequency spectrum through the system after the changes. System function, according to canonical structure (canonical form) the preparation of a sample processing algorithm.)
