代码说明:

>> w1 = 0 ;w2 = 0.3 * pi;delta1 = 0.01 ; >> w3 = 0.4 * pi;w4 = 0.7 * pi;delta2 = 0.005 ; >> w5 = 0.8 * pi;w6 = pi ;delta3 = 0.001 ; >> 权重 = [delta3/delta1 delta3/delta2 1]; >> Dw = min((w3-w2),(w5 w3)) ; >> M = ceil((-20*log10((delta1*delta2*delta3)^(1/3))-13)/(2.285*Dw)+1) >> M = 51 >> f = [0 w2/pi w3/pi w4/pi w5/pi 1]; >> m = [1 1 0.5 0.5 0 0]; >> h = firpm(M-1,f,m,weights) ; >> [db,mag,pha,grd,w] = freqz_m(h,[1]);

    因为傅立叶变换对应的是无限信号,信号经过分帧后变成有限信号,分帧的信号再进行傅立叶变换后,高频部分将有 泄露 ,所以要加窗. 窗函数的拼谱都是在某高频部分截止,所以每帧信号加窗后的傅立叶变化,频谱基本 泄露 (Because Fourier transform corresponding is infinite signals, signals after framing become limited, framing signal again after Fourier transform, the high frequency part will have leaked , so to add window. Window function spell spectrum are in a high frequency part of the globe, so each frame and window after Fourier transform, signal spectrum basic leak )
