分析比对了均值滤波和中值滤波两种方法，对彩色图像滤波处理的优劣(Analysis compared the mean filter and median filter are two methods, the merits of color image filtering)

基于一个二阶线性系统实例，介绍了全程滑模变结构控制，实现了系统的鲁棒性特点。(Global sliding mode variable structure control, based on a second order linear system instance, the robustness of the system characteristics.)

利用Van der Pol范德波方程，仿真ECG信号，并计算其功率谱等参数(Fan Debo use Van der Pol equation, simulation ECG signal and calculate the power spectrum and other parameters)

实验二　离散时间傅里叶分析 1． 离散时间信号 ， ，求 的傅立叶变换 。 离散时间信号 ， ，求 的傅立叶变换 (Experiment 2 discrete-time Fourier analysis 1. Discrete-time signal, find the Fourier transform. Discrete-time signal, find the Fourier transform)

说明：  滚动轴承故障诊断是机械故障检测中一个重要方面。使用小波包分析和包络分析相结合的方法提取轴承微弱振动信号, 克服了传统包络分析方法易丢失信号有效成分的缺点。包络信号的细化谱较好体现了轴承故障信息。(Bearing Fault Diagnosis of mechanical fault detection in an important aspect. The use of wavelet packet analysis and envelope analysis method of combining extracts bearing vibration signal weak to overcome the traditional envelope analysis method easy to lose the signal disadvantage of the active ingredient. Refinement of the envelope signal spectrum better reflects the bearing fault information.)

FDTD时域有限差分法matlab仿真TM模场分布(FDTD FDTD method matlab simulation TM mode field distribution)

用matlab完成包络检波，可以实现整个过程，适合初学者。(Complete envelope detection with matlab, you can achieve the entire process, suitable for beginners.)

说明：  这个功能是用于Matlab中的某个功能所使用的，非常好的一个原代码！(This feature is used in a Matlab function used, very good a the original code!)
