The step response of an LTI system is given by [itex] s(t) = e^{-t}u(t) [/itex]. Find its response to the input [itex] u(t) - u(t-2) [/itex].
Note: [itex]u(t)[/itex] is the unit step function.
So I have the solution, but I do not understand it.
[tex] y(t) = s(t) - s(t-2) = e^{-t}u(t) - e^{-(t-2)}u(t-2) [/tex]
I really don't understand where this is coming from. If somone could guide me to this solution, that would be good.
Thanks!
