Expressing signal as a sum of functions

  1. Sep 3, 2014 #1
    1. The problem statement, all variables and given/known data

    V(t) = [2t - 4] u(t) u(4 - t)

    I need to express this a sum of step and ramp functions.



    2. Relevant equations



    3. The attempt at a solution
    I have absolutely no idea how to proceed

    Sorry

    Sorry I have been really busy and unfortunately I was not able to reply to your comments soon
    enough. Yes, it is unit step time, and I have no idea how to do the question

    Can you explain in words what features an observer would see in this function: V(t) = 2t

    I would need at least 50 words, you may need a few more than that.
