说明：  介绍MATLAB使用的相关知识和技巧，对入门者比较有用。(MATLAB introduce the use of relevant knowledge and skills useful for beginners comparison.)

小波分解与重构，单纯就是小波的分解和重构的m文件，没有其他多余没有用的文件，信号处理图像处理都很有用(Is simple wavelet decomposition and reconstruction of m documents, no other extra useless files, signal processing, image processing is very useful)

matlab中结合小波和偏度对故障信号的处理(matlab combination of wavelet and skewness of the fault signal processing)

Soluç ã o de Equaç ã o Diferencial Ordinária - Método do Ponto Médio

设计一个8阶以内的带通滤波器，通带截止频率fc1=30070HZ，fc2=32170HZ，通带内允许最大衰减0.2dB。设计满足要求的Butterworth滤波器和chebyshev滤波器。以RC运放为基本单元以最易实现的原则完成电路设计及参数选择，并根据设计参数进行幅频特性和相频特性的仿真，给出仿真曲线。分析电路的无源灵敏度。(Design within an 8-order band-pass filter, the passband cutoff frequencies FC1 = 30070HZ, FC2 = 32170HZ allow maximum attenuation 0.2dB within the passband. Designed to meet the requirements of the Butterworth filter and chebyshev filter. RC op amp is the basic unit is the most easy to implement the principle of complete circuit design and parameter selection, and in accordance with the design parameters of the amplitude-frequency characteristics and phase-frequency characteristics of the simulation, simulation curve. Passive sensitivity of the analysis circuit.)
