1.依据二中滤波器参数生成滤波器(参数输入后点击design filter) 2.生成后,点击file—Generate MATLAB code—Filter Design Function。生成对应程序并保存 3.生成程序如下: function Hd = FDAtool_test_BUTTER %FDATOOL_TEST_BUTTER Returns a discrete-time filter object. % MATLAB Code % Generated by MATLAB(R) ...
(1)以.m文件的形式导出到matlab中: 1)点击file,然后选择Generate MATLAB Code -> Filter DesignFunction: 2)在当前文件目录中修改导出文件名为Filter_IIR.m,点击保存: 3)然后就可以看到已经设计好的滤波器代码。 4)调用设计好的滤波器: 在MATLAB中新建一个.m文件,然后在文件中添加如下代码: %% % 作者:明志 ...

Matlab provides different options for digital filter design, which includes function, calls to filter algorithms and a graphical user interface called Sptool. A variety of filter design algorithms are available in Matlab for both IIR and FIR filters. This paper discusses the different options in ...
function[yn]=user_filter(Bz,Az,xn)%xn是输入的向量%yn是输出的向量nz=size(Az,2);n=size(xn,2);yn=zeros(1,n);Xbuf=zeros(1,nz);Ybuf=zeros(1,nz);fori=1:n%更新Xbuf和Ybufforj=1:nz-1Xbuf(nz+1-j)=Xbuf(nz-j);Ybuf(nz+1-j)=Ybuf(nz-j);end%更新差分方程Xbuf(1)=xn(i...
Another design function for optimal equiripple filters is firgr. firgr can design a filter that meets passband/stopband ripple constraints as well as a specified transition width with the smallest possible filter order. For example, if the stopband-edge frequency is specified as 10 kHz, the resul...
1.辅助设计 Filter Designe & analysis Tool,通过辅助工具设计,比较省事 进去观察下有哪些选项可以设置 大部分还是基本看了就知道需要怎么设,然后就是准备导出传递函数 FILE中的EXPORT,然后设置10进制输出 最后就能导出相应的传函 % % Generated by MATLAB(R) 7.8 and the Signal Processing Toolbox 6.11. ...
