“…Inequalities (13) and (15) shed considerable light on the fundamental properties of an N -port network containing a controlled source subnetwork. In fact, at poles of Y which are not poles of Yo , these conditions yield explicit restrictions on the Y matrix.…”
The following basic theorem concerning active RC networks is proved: Theorem: A n arbitrary N X N matrix of real rational functions in the complex-frequency variable (a) can be realized as the short-circuit admittance matrix of a transformerless active RC N-port network containing N real-coefficient controlled sources, and (b) cannot, in general, be realized as the short-circuit admittance matrix of an active RC network containing less than N controlled sources.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
