system with impulse response hn ! = un- x[n] = u[n]-u[n-4]. Compute Y(z) X(z)H(z) and use Y(z) to compute y[n].
Question: Given y{n}=2*x[n], what does the impulse response tell us about its stability? aside: Stability is when you have a bounded input, you get a bounded output. And its bounded if its absolutely summable. So is the delta function (impulse response is an impulse times a constant) absolutely summable? What is the absolute value of an impulse response...just 1?
