example4_6
：滤波
fs=400 采样频率,必须大于两倍基带信号最高频率
ts=1/fs 采样时间间隔
T=5 时间窗大小
t=0:ts:T (hf1=zeros(1,N)
hf1(f<=B1&f>=-B1)=1
y1=hf1.*fftshift(y)
figure
subplot(211)
plot(f,abs(fftshift(y))/N,f,hf1, r-- )
axis([-fs/2,fs/2,0,1.2])
title( 原信号频谱 )
xlabel( f /Hz )
subplot(212)
plot(f,abs(y1)/N)
title( 低通滤波，截止频率90Hz )
