A general transformation with applications to circuit theory
Journal of the Franklin Institute, 1968Abstract A general functional transformation is introduced and some applications to circuit theory are given. The transformation is most useful in the area of active, nonbilateral circuits. This functional transformation introduces new voltages and currents which are linear combinations of the original voltages and currents plus their derivatives ...

The general theory for analysis of subharmonic oscillations at a frequency of ω/3 in three-phase ferroresonance circuits is presented. The occurrence and existence of ferroresonance oscillations at subharmonic frequencies in power transmission lines and power supply systems is highly undesirable, since they cause overvoltages at various frequencies. At

A generalized equivalent circuit in the theory of polyphase commutator motors
Electrical Engineering, 1941The demand for speed variation and power-factor compensation in a-c motors led to the development of the polyphase commutator types. In their simplest form these motors consist of two windings; a stator winding which is identical with that of the polyphase induction motor and a rotor winding of the closed type provided with a commutator and similar to ...

A General Theory of Circuit Analogy in Fracture Diagnosis.
1984Abstract : The present report develops electrical analogs to investigate multiple cracks on simple beams and more complex frame structures. Analog networks provide the economic tool to analyze such structures. The effect of multiple cracks on the natural frequencies of simple structures is studied in detail.

Elements of general theory of null-balance circuits
1998 Midwest Symposium on Circuits and Systems (Cat. No. 98CB36268), 2002The null-balance method of output indication is widely used in instrumentation techniques and sensor applications. Yet, the theorems and methods of general circuit theory that are the basis of the null-circuit analysis and design have nearly disappeared from the modern books on network theory.

Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03., 2003
This paper presents a general analysis of the 3rd-order nonlinearity of a single-ended and differential common-emitter (CE) radio frequency (RF) amplifier. With direct computation of the third-order nonlinear response, a closed-form expression was derived. The results suggested several novel ways to cancel the third-order nonlinearity without affecting

IEEE Transactions on Circuits and Systems I: Regular Papers, 2019
In this paper, the application of the theory of Lissajous figures to the creation of pinched hysteresis loops, considered to be a characteristic of memristive systems, is demonstrated and experimentally verified using designed electronic circuits in the form of an input impedance.

We generalize Kirchoff’s law for multiply connected wire networks to finite frequencies. We focus on the boundary conditions not present in the conventional Kirchoff’s law at joints when more than three wires come together, which is absent in our previous “circuit theory” for the finite frequency properties of metallic wire networks for singly ...

The general fluid circuit theory of active chloride absorption
The Bulletin of Mathematical Biophysics, 1940The original fluid circuit theory used to explain active intestinal absorption of chloride is modified to include diffusion and secretion of chloride and osmosis. The general differential equation developed is integrated in a particular case. The definition, “effective concentration of chloride in the fluid passing into the intestinal lumen,” leads to ...

Physical Review B, 2006
Extensions of an existing circuit theory for current perpendicular to plane magnetoresistance and current-driven torque in noncollinear magnetic-multilayer pillar devices are presented. Our expressions for monodomain critical-current threshold ${J}_{c}$ and giant magnetoresistance $\mathrm{\ensuremath{\Delta}}R$ are firstly derived in terms of assumed ...
