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:

    h[n]=((0.5)^n-(0.25)^n)u[n]

    find y[n].

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

    In order to obtain the output, you need the input waveform and the initial conditions. What are they?
