现代信号处理 一个序列为 ，使用FFT分析其频谱： 1） 使用不同宽度的矩形窗截短该序列为M点长度，取M分别为： a) M=20 b) M=40 c)M=160 ；观察不同长度的窗对谱分析结果的影响； 2）使用汉宁窗、哈明窗重做1） 3）对三种窗的结果进行理论分析及比较。并绘出相应的幅频特性曲线 (Modern signal processing a sequence, using FFT analysis of the spectrum: 1) the width of the rectangular windows with different truncated point of the sequence length of M, take M, respectively: a) M = 20 b) M = 40 c) M = 160 observation windows of different lengths affect the results of spectral analysis 2) Hanning window, Hamming window redo 1) 3) the results of three windows and compare the theoretical analysis. And draw the corresponding amplitude-frequency characteristic curve)

VB程序中实现调用MATLAB的方法。本文介绍了在VB应用程序中利用动态数据交换ActiveX自动化(OLE自动化)协议实现的两种调用MATLAB函数的方法。通过这两种方法实现了VB的可视化界面与MATLAB强大的数值分析和图形显示的能力的结合。(VB program called MATLAB to implement the method. This article describes the application in VB using ActiveX Automation Dynamic Data Exchange (OLE Automation) protocol to achieve the two call MATLAB functions. Achieved by these two methods VB' s powerful visual interface and MATLAB numerical analysis and graphical display of the ability of the combination.)
