This problem is in the context of discrete systems and signals.
My goal is to find an equation for y(n) without the summation.
where is the unit step function
So I need to eliminate the unit step functions from the equation by changing the limits of summation:
if then . And so it's eliminated from my summation above.
if then . And it's also eliminated.
So my limits of summation are and . But the limits don't define a finite range! Can anyone help?
