Heaviside function problem

  1. Feb 2, 2006 #1
    hey guys, Im having a bit of trouble finding the equation for the following graph.

    I know it should look something like: u(t)-2u(t-2), but I dont really understand it.

    Can someone point me in the right direction?

    We can't view the graph yet as it is listed as an "Attachment Pending Approval". Describe it, e.g.

    u(t)-2u(t-2), is 0 for t<0, 1 for 0<=t<2, and -1 for t>=2.

    Note that I have assumed that u(t) is 0 for t<0 and 1 for t>=0.

    Oh ok. Sorry about that.

    Well: g(t)= 1 for 0<t<2
    and g(t)= -1 for t>2

    And g(t)=0 for t<0

    edit: I just read what you wrote. It sounds like what Ive got. Looks like I did kinda understand what I was doing afterall. Cheers.
