Certain properties of the network of departure

and the padding network

of an (

)-node resistive

-port network containing no negative conductances are established. Based an these properties, some necessary conditions and a sufficient condition for the realizability of the

matrices of (

)-node resistive

-port networks are obtained. A new proof for the supremacy condition is given. Also, a necessary and sufficient condition for the realization of (

)-node

-port networks having specified

and

matrices is given.
