This question came out for my exam.
Impulse response h(t) = u(t) - u(t-1)
Find output when input is x(t) = (t^2 + t)u(t)
Do I use the equation ∫x(τ)h(t-τ)dτ from 0 to infinity or do I use laplace transform?
Since u(t) - u(t-1) is one from 0 to 1, I reduced the integral to the limits 0 to 1 and continued on from there. Am I right or wrong?
However, when I use laplace transform I get a totally diff answer. Which is right?
