例3:分析占空比为ta的矩形脉冲频谱
T=1 时间窗大小
ta=0.5 占空比
N=256
t=linspace(-T,T,N)
ts=2*T/N
fs=1/ts
(x=zeros(1,N)
x(N/2-round(N/2*ta):N/2+round(N/2*ta))=ones(1,2*round(N/2*ta)+1)
y=fft(x,N)
figure
plot(t,x)
title([ 时域信号图 占空比为 ,num2str(ta)])
axis([-T T-0.2 1.2])
xlabel( t /s )

subplot(211)
f=linspace(-fs/2,fs/2,N)
plot(f,abs(fftshift(y))/N)
