Convolution of two functions

  1. Oct 2, 2011 #1
    1. The problem statement, all variables and given/known data
    h(t) = u(t) (the unit step function)

    x (t) = e-t



    3. The attempt at a solution

    There is only one interval where the two functions overlap, and that's from 0 to t.

    The integral from 0 to t of e-[itex]\tau[/itex] d[itex]\tau[/itex] = -e-t

    Doesn't look right to me... what am I doing wrong?

    EDIT: This is discrete convolution, by the way.
