Fifty years ago, the author and his students studied the analytic properties of network functions of nonuniform RC and LC transmission lines and obtained the necessary and sufficient conditions for a transcendental function to be a network function o

We present and prove a new sufficient condition for convergence of the general waveform relaxation algorithm in the solution of a system of nonlinear differential–algebraic equations. The proof is based on the spectral theory of linear operators. T

We present a monotone waveform relaxation algorithm which produces very tight upper and lower bounds of the transient response of a class of systems described by nonlinear differential-algebraic equations (DAEs) that satisfy certain Lipschitz conditi

In this note, we derived the expressions of the spectra and pseudospectra of waveform relaxation operators for general linear differential-algebraic equations of index one. The expressions are generalizations of those of Lumsdaine and Wu (SIAM J. Sci

Gallium Arsenide technology has come of age. GaAs integrated circuits are available today as gate arrays with an operating speed in excess of one Gigabits per second. Special purpose GaAs circuits are used in optical fiber digital communications syst

The cascaded two-port circuit theory is generalized and applied to the approximation of the square root of a rational function by a function in the form of a chain of linear fractional transformations. We prove the convergence of the approximation, a

In this paper an important property of the time responses of coupled transmission lines is proven. Based on this property coupled transmission lines are synthesized from the given near-end and far-end time-domain responses. The inductance matrix L an

Recently, the waveform generalized minimal residual method (WGMRES) was proposed for solving differential-algebraic equations problems. Based on this, several waveform Krylov subspace methods are developed for comparison. Particularly, we propose usi

We proved in this paper that, a system composed of identical sub-systems that are cross-coupled in certain manner is capable of generating multi- or quadrature-phase oscillation signals under specified conditions. Based on the theory, an RC multi-pha

In this paper nonuniform transmission lines are synthesized by the method of characteristics in the time-domain. Given m sample values of the near end response at m time points, the impedance profile of a lossless nonuniform line represented by m uni
