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
