Original Abstract

In the paper a technique of the simulation of transient phenomena in linear lumped-distributed circuits using Matlab language is presented. Distributed parts can be multiconductor transmission lines (MTL), generally nonuniform, frequency–dependent, and under nonzero initial conditions. In principle the solution is formulated by means of a modified nodal admittance matrix equation method in the frequency domain. Then an improved fast method of the numerical inversion of Laplace transforms (NILT) is applied to obtain a solution in the time domain. This NILT method is based on the FFT and quotient-difference algorithm of Rutishauser to ensure both high speed of computation and sufficient accuracy.
