Homework Statement
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.
Homework Equations
None.
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.
