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 ...
