AbstractThe problem of realization of a given real symmetric matrixRof ordernas an open‐circuit resistance matrix of some resistiven‐port network having nullitynis considered in this paper. The solution presented is in the form of a realization technique which implies the necessary and sufficient conditions for this type of realization. Derived from fundamental topological considerations in the analysis of resistiven‐port networks, the realization technique presented here is found to be superior to the existing
