今天清明放假的第二天,早晨出去吃饭时天气有些阴,十点多开始“清明时节雨纷纷”了. 母亲远在他乡看孙子,挺劳累的.父亲照顾生病的爷爷…… 我打算今天把<DSP using MATLAB>第7章结束,剩下的几个例子看不懂了,先跳过去. ch7最后一个: 代码: ws = 0.6*pi; wp = 0.75*pi; Rp = 0.5; As = 50; [delta1, delta2] = db2delta(Rp, As); f = [ws, wp]/pi; m = [0, 1]; delta =…

前几天看了看博客,从16年底到现在,3年了,终于看书到第9章了.都怪自己愚钝不堪,唯有吃苦努力,一点一点一页一页慢慢啃了. 代码: %% ------------------------------------------------------------------------ %% Output Info about this m-file fprintf('\n***********************************************************\n');…

参照Example7.27,因为0.1π=2πf1   f1=0.05,0.9π=2πf2   f2=0.45 所以0.1π≤ω≤0.9π,0.05≤|H|≤0.45 代码: %% ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ %% Output Info about this m-file fprintf('\n**********************************…

x = [3, 11, 7, 0, -1, 4, 2]; nx = [-3:3]; h = [2, 3, 0, -5, 2, 1]; nh = [-1:4]; [y,ny] = conv_m(x,nx,h,nh) 结果:…
