    What is a feedback polynomial good for?

    Hi there

    When I got a linear relation s_{m+2}=s_m-s_{m+1} its characteristic polynomial is x^2+x-1 and its feedback polynomial is -x^2+x+1 but what is the sense of a feedback polynomial?

    Where is it used? Where is it applied? In engineering or anywhere?

    Regards
