电机拖动里的用空载点和负载点做出直流电机的固有机械特性曲线(failed to translate)

这是一个低通抽样定理，例题中包括了低通信号的波形，抽样速率为4Hz的抽样信号，抽样序列恢复出原始信号(This is a low-pass sampling theorem, examples included in the lowpass signal waveform, the sampling rate is 4Hz sampling signal to recover the original signal sample sequence)

主要是关于电力系统的仿真实验。内容有些残缺，但是可以当做练习题。里面有一些原理图，有模型搭建图。比较有学习价值。(Mainly on the power system simulation. Some content incomplete, but can be used as exercises. There are some schematics, there are models to build map. Compare with learning value.)

实时跟踪摄像头获取视频中的红色部分，算法由Matlab实现。计算机要有摄像头或连接USB摄像头，Matlab通过自身函数提取视频跟踪。 包含两个文件，word说明了matlab提取视频方法。m文件实现算法，其中摄像头参数部分代码可能视具体情况修改。(Get real-time tracking camera video in the red part of the algorithm by Matlab implementation. Computer must have a camera or connect a USB camera, Matlab function to extract the video track by itself. Contains two files, word describes a method to extract video matlab. m file algorithm, which camera parameters of the code, as the case may be modified.)

完成一维信号小波去噪，并比较不同阈值的去噪效果(Complete one dimensional signal wavelet de-noising)

说明：  对未来的人口数量进行一定的预测，采用的是阻滞增长模型(Predict the future population)

最小二乘支持向量机,用于多元非线性回归分析,非线性拟合与预测(Least squares support vector machine for multi-linear regression analysis, nonlinear fitting and prediction)

说明：  动画电影制作样例，很有帮助，很好，国外牛人写的，规范(Animated film production sample, helpful, well, foreign cattle were written, standardized)

利用双线性变换法，设计一个0.4dB截止频率为10kHz且在30kHz处有最小阻带衰减为50dB的数字巴特沃兹低通滤波器，其抽样率为100kHz。利用教材（4.35）式求解原型模拟滤波器的阶数，并利用Matlab的M文件buttap设计模拟原型滤波器。用M文件bilinear将模拟滤波器传输函数变换成期望的数字传输函数。请用Matlab画出其增益和相位响应，并给出设计的具体步骤。(fuck!!!)
