Homework Help: Finding the difference equation given the impluse response

  1. Sep 8, 2009 #1
    This question is for a DSP class. I hope that I am posting somewhere appropriate.

    So given the impulse response:


    find y[n].

    Where do I start? I dont need an answer, just a nudge in the right direction.
