matlab设计程序用FFT对信号作频谱分析(matlab program designed to make the signal with the FFT spectrum analysis)

matlab在振动信号处理中的应用代码，基本包含所有基础的信号分析(Signal analysis matlab vibration signal processing application code that contains all the basic foundation)

这个程序使用vc++实现的一个工程，这个工程的作用就是完整实现了MATLAB和vc++混合编程的关键函数的功能-mexfunction。有其详细的开源代码！(This program uses the vc++ implementation of a project, the role of this project is to complete implementation of the MATLAB and vc++ mixed programming function of the key functions-mexfunction. Has its open source code in detail!)

风机仿真的风况模型，能生成三类风机、三类湍流强度下的NTM、ETM、EWM、EOG及ECD各种风况下实时风速(Fan, the simulation of the wind model can generate three kinds of blower, NTM under three kinds of turbulent intensity, ETM, EWM, EOG and ECD for real-time wind speed under different wind conditions)

现有一个信号：x(n)=1+cos(π*n/4)+ cos(2*π*n/3)设计及各种数字滤波器以达下列目的： 低通滤波器，滤除cos(2*π*n/3) 的成分，即想保留的成分为1+cos(π*n/4) 高通滤波器，滤除1+cos(π*n/4) 的成分，即想保留的成分为cos(2*π*n/3) 带通滤波器，滤除1+cos(2*π*n/3) 的成分，即想保留的成分为cos(π*n/4) 带阻滤波器，滤除cos(π*n/4) 的成分，即想保留的成分为1+cos(2*π*n/3) 1. 用MATLAB命令butterord求除滤波器的阶数,用命令butter设计各滤波器；画出滤波器幅度和相频相应 取各滤波器的系统函数H(z)。 (an existing signal : x (n) = a cos (* n/4) cos (2** n/3) design and digital filter to achieve the following objectives : low-pass filter, filter cos (2** n/3) the ingredients that want to retain an element of a cos (* n/4) high-pass filter, a filter cos (* n/4) components, namely to retain the element of cos (2** n/3) band-pass filter , a filter cos (2** n/3) components, namely to retain the element of cos (* n/4) band stop filter, the filter cos (* n/4) components, namely to retain the ingredients for a cos ( 2** n/3) 1. MATLAB order butterord except for the band Filter, using the order of the filter design butter; paint Filter magnitude and phase frequency of the corresponding filter system function H (z).)
