数字信号处理实验的代码,仅参考

error1=max(abs(xa1-xa)) Fs2=1/Ts2; nTs2=n2*Ts2;

xa2=x2*sinc(Fs2*(ones(length(n2),1)*t-nTs2'*ones(1,length(t)))); subplot(4,2,8); plot(t*1000,xa2); ylabel('xa2(t)');

error2=max(abs(xa2-xa))

x1=[-1 1]; x2=[-2 1]; x3=x1+x2; x=[x3(1):x3(2)] h1=[1 2 3]; h2=[2 4 3 5]; h=conv(h1,h2); stem(x,h);
