how to calculate convolution
显示 更早的评论
i need help,i want to calculate the convolution of two discrete time signal but an error has occurred
n=-20:20;
delta=(n>=3 & n<=8);
x=delta;
% x denotes x[n]
delta=(n>=4 & n<=15);
h=delta;
% h denotes h[n]
subplot(3,1,1)
stem(n,x,'filled');
xlabel('n');
ylabel('Amplitude');
title('X[n]');
subplot(3,1,2)
stem(n,h,'filled');
xlabel('n');
ylabel('Amplitude');
title('h[n]');
subplot(3,1,3)
c=conv(x,h);
stem(n,c,'filled');
xlabel('n');
ylabel('Amplitude');
title('y[n]');
help me find the error in the coding...

What error did you get?
Did you read the help for the conv function? Why not?

Can any one solve this question Compute the convolution y[n] = x[n] * h[n] when 𝑥(𝑛) = 𝑎𝑛u(n),0 < a< 1, ℎ(𝑛) = 𝑏𝑛u(n), 0 < b< 1 Assume that a and b are not equal.

This is not an answer for Zeeshan. Please start your own question and explain why y=conv(x, h) does not work for you. And explain your definition of u.
