Homework Help: From a transfer function to a difference equation

  1. Dec 31, 2011 #1
    Hello.

    I have been given a transfer function for a digital system, and I need to find the difference equation for that system.

    I have attached a pdf with my work. I would be grateful if someone could take a look at it, and see if I am along the right lines.

    Thanks in advance, and happy new year to you all.

    I thought I had responded to this before.

    You have a typo in your 6th equation, 3rd term on RHS.

    Otherwise, I see nothing wrong with your derivation of the differencce equation.
