 note = {The Helmholtz-Thévenin theorem together with its dual equivalent Mayer-Norton's one is generalized to that of n-terminal networks. The new theorem asserts that any n-terminal network can be reduced to a set of the equivalent circuits which consist of (n-1) (n-2)/2 impedances and (n-1) active 2-terminal elements (Helmholtz-Thevenin's or Mayer-Norton's equivalent circuits). Their graph is the complete one, and the active elements are connected to each other so that they make a tree. The number of the possible equivalent circuits is n^n-2 for an n-terminal network, if we do not distinguish a Helmholtz-Thévenin's circuit from Mayer-Norton's one., 紀要論文},
