Circuit diagnosis and Thevenin equivalents
Proceedings of the IEEE, 1982Roytman and Swamy have used the properties of orthonormal excitations to establish one method of circuit diagnosis. In this letter the method is extended to determine the driving-point or Thevenin equivalent impedance for each node pair.
