Any synthesis process based on a node-pair or mesh matrix must take cognizance of the sign pattern of the matrix. It is proved in general terms in this paper that: (1) the only subgraph of a connected graph G wbich need be of concern in studying the sign pattern of the node-pair (mesh) matrix is th
