Abstract A new geometric-analytic theory of noisy two-port networks is presented.It is based, geometrically, on the isometric sphere method, a generalization of the isometric circle method to three… Expand

A procedure is presented for connecting some known physical applications of Fourier transform pairs in different branches of the theory of waves and circuitry. After an investigation of the cases of… Expand

A geometric-analytic theory of transition is presented and applied to circuit theory. A transition from one state to another is represented in a complex plane by two points which, by variation of a… Expand
