## Homework Statement

evaluate and plot this convolution:

y[n] = 2^n u[n+4] * u[n-3]

## Homework Equations

## The Attempt at a Solution

This is my code:

n0 = 20;

n = -n0:n0;

u1 = (n+4)>=0;

f1 = 2.^n;

x = f1 .*u1;

h = (n-3)>0;

y = conv (x,h);

l = length(x)+length(h)-1;

k2 = linspace(-n0,n0, l);

stem (k2, y);

xlabel ('n');

ylabel ('impulse response');

title ('System unit impulse resopnse Q1');

I get a plot, but I get suspicious about it because it doesn't seem to converge, so i change n0 (just to see) and make it 100, it still looks the same. I make it 1000, 0,-10, it still looks the same which tells me there is something wrong in my code. Awaiting your help.
