NETWORK REALIZABILITY THEORY AND ITS APPLICATION TO THE SYNTHESIS OF DISTRIBUTED PARAMETER MATCHING NETWORKS

摘要

A general theory of network realizability for linear, passive, time-invariant networks is presented from the point of view of energy conservation and causality. It is shown that four postulates defining the physical nature of a network suffice to give all the analytic pro¬perties of the network scattering matrix. These analytic properties de¬fine a bounded real scattering matrix, the possession of which is nec¬essary and sufficient for an n-port network to satisfy physical realiza-bility as stated by the given set of postulates. A theorem concerning the necessary and sufficient conditions for the existence of a Faltung-representation is proved and its implications discussed.
