This MATLAB function designs a lowpass IIR filter with the filter order of 10 and half-power frequency of 0.25.
The primary advantage of IIR filters over FIR filters is that they typically meet a given set of specifications with a much lower filter order than a corresponding FIR filter. Although IIR filters have nonlinear phase, data processing within MATLAB® software is commonly performed “offline,” th...

matlab IIR filterDesigner 仿真 文章分类 本示例说明了如何应用imfilter函数,使用包含相等权重的5×5滤镜(通常称为平均滤镜)对2D灰度图像进行滤波。该示例还显示了如何使用相同的滤镜对真彩色(RGB)图像进行滤波。真彩色图像是大小为[m,n,3]的矩阵,其中最后一维表示三个颜色通道。使用2-D滤镜滤波真彩色图像等效于...
matlab可以很方便的设计各种滤波器。具体就是命令行输入‘filterDesigner’弹出设计框。如下图,图上方的几个小方框对应着幅频响应、相频响应等。 举个例子,设计一个IIR滤波器,采样率为32000Hz, 有用信号频率在10000Hz内,设计IIR滤波器对信号进行数字滤波。
