Homework Help: How do you find initial values for linear discrete time systems?

  1. Dec 14, 2011 #1
    Can someone the following steps of this solution for me?


    Mainly how they got their initial conditions? The 7.30 equation is just h[n-m] = bm which doesn't help me much.

    For our problem, I know that n=3 and m =1 since the LHS highest degree is +3 and RHS highest degree is +1

    then h[3-1] = h[2] = 6 because coefficient b1 which is in front of f[k+1] is 6. At least that is what I think. Correct me if I am wrong.

    But then how do they obtain h[1] and h[0]? Why are we plugging in values for K?
