On Some Passive Dual Input Null Networks

Abstract

This paper deals with dual input networks which do not use any active device. Four networks are considered, including the familiar bridged-T RLC network and the parallel-T RC network, and the not so familiar Hall’s second network and the three section bridged-T RC network. All of them are thoroughly analyzed, expressions for the transfer functions are given, and the relevant characteristic parameters are recorded. Simulations are carried out to display the characteristics, and observations are made. Conclusions are given at the end.
