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。左下方可选择滤波器类型和具体参数等。 举个例子,实现采样频率2kHz,带宽为100Hz～300KHz带通滤波器。 设计一个128阶的FIR带通滤波器,Fstop1为100Hz, Fpass1为110Hz...
This example shows how to use windowing, least squares, or the Parks-McClellan algorithm to design lowpass, highpass, multiband, or arbitrary-response filters, differentiators, or Hilbert transformers.
在MATLAB的命令窗口,输入fdatool(新版MATLAB为filterDesigner)回车, 滤波器设置界面 这里选择低通FIR,窗函数选常用的几个,这里选择了汉明窗;滤波器阶数选择72,阶数越高滤波效果越好,但资源占用越多;FS/FC(采样率/截止频率)为50:3,点击Design Filter会显示相应的频率响应图,由于FIR滤波器抽头的特性,当输入的采样率为...

This MATLAB function uses a Hamming window to design an nth-order lowpass, bandpass, or multiband FIR filter with linear phase.
使用matlab 做 FFT 进行频谱分析,使用 7 阶(8个系数)FIR 滤波器能够很好的保留低频 0.5 MHz 信号,滤除高频 13 MHz 信号; (3) 综合的 RTL 图 综合后共用到 6 个乘法器和 7 个加法器, Verilog 共计有 8 次乘法,但是其中有 2 个乘法的乘数是常数 0,所以 Vivado 只综合出 6 个乘法器; ...
参看Matlab的输出图形和参数是否满足要求。 2.1.5 Matlab直接FDAtool设计方式解析 FDATool(Filter Design & Analysis Tool)是MATLAB信号处理工具箱里专用的滤波器设计分析工具,MATLAB6.0以上的版本还专门增加了滤波器设计工具箱(Filter Design Toolbox)。FDATool可以设计几乎所有的基本的常规滤波器,包括FIR和IIR的各种设计方...
