【滤波器设计】根据设计指标使用matlab定制滤波器
2022-06-29 03:42:00 【fpga和matlab】
滤波器设计指标如下:

clc;
clear;
close all;
warning off;
%use the windows function
N = 25; %阶数,可以用过渡带来计算
wc = 1/6; %wc是过渡带中心,要除以pi
hn = fir1(N-1,wc,'low',Bartlett(N));
%要求a
disp('the cofficient of windows is');
hn'
figure;
plot(hn,'b-o');
title('the cofficient of windows');
%要求b
figure;
freqz(hn,1);
得到滤波器系数如下:
the cofficient of windows is
