(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A DT system has the unit response h[n] = (0.2(1.3)^n)u[n]. You then input x[n] = sin(n*pi/2)u[n]. Find the convolution.

2. Relevant equations

None.

3. The attempt at a solution

>> n = 0:30;

>> h = 0.2*(1.3).^n;

>> x = sin(n*pi/2);

>> s = conv(h,x);

I left out u[n] because we know that u[n] = 1 whenever n >= 0 and 0 when n < 0. So, if I am correct, it is just multiplying the input by 1, if n >=0.

This should be right, just wanted to verify.
