DESCRIPTION:Everyone knows that right-half plane zeros are associated with
  inverse response of (continuous time) linear systems. It is known that th
 e presence of a real right-half plane zero is sufficient for inverse respo
 nse to exist\, and it is easy to demonstrate that complex right-half plane
  zeros are not sufficient to produce inverse response. So the question ari
 ses: are right-half plane zeros even necessary for inverse response to exi
 st? The short\, but incomplete\, answer\, is “no”. Counter-examples ha
 ve been generated by using the Levinson-Durbin parametrisation of Schur-st
 able polynomials together with a standard bilinear transformation.
