Abstract: Rantzer (1992) established a fundamental bound on the rate of change of phase of a Hurwitz polynomial. An inductive proof given in Bose (1994) has stated that this fundamental bound can be derived from Tellegen's theorem in network theory, the purpose of this paper is to give a direct proof of the fundamental bound using the Hermite-Bieler theorem which, in turn, follows from the monotonic phase property and total phase change properties of a Hurwitz polynomial, this is instructive because control engineers are, by and large, unfamiliar with Tellegen's theorem, and the authors' direct proof makes transparent the central role played by these phase properties.
