Homework Help: Z-Transform, Cant find this transform

  1. Jun 9, 2012 #1
    1. The problem statement, all variables and given/known data
    I am attempting to perform a z-transformation on the terms 1/(z-3) and 1/(z-5) but I cannot find a sequence which fits this form in any of my tables. Is there a transform for these terms or do you just leave them as they are?


    2. Relevant equations



    3. The attempt at a solution

    I just left them as they were but Im not sure if thats the correct form

    Question is unclear. They're already z transforms. Are you looking for the inverse transforms?

    Assuming you want to expand your z tranfer functions, use the standard method of long division to come up with a series:

    1/(z-3) = 1Ʃanz-n etc.

    Then the inverse transform is of course immediately at hand.
