A note on the stability of delta-operator-induced systems
This correspondence points out that stability of delta-operator-induced real polynomials is equivalent to a shifted Hurwitz stability of their reciprocal counterparts. This fact reveals a simple and clear link between the delta-domain stability and Hurwitz stability for real polynomials.
