DETERMINATION OF THE TRANSMISSION LINE RESISTANCE MATRIX WITH DEVIATIONS OF DESIGN PARAMETERS FROM NOMINAL

Context. UHF transmission systems make extensive use of line segments, the characteristics which have a significant impact on performance various information technologies. One problems production lines is to obtain given wave impedance, significantly affects electrical and entire set equipment. Currently, there burning issue estimating influence disturbing factors long segments. To date, most fully developed methods for assessing effect impedance homogeneous (the constant) under regular perturbations. In this case, perturbations reflection coefficient matched was mainly considered. The other and, especially, inhomogeneous has not been sufficiently studie
 Objective. purpose paper determine matrix. Knowing perturbed matrix, it possible distortion any device built 
 Method. uses method perturbation theory linear differential operators applied equations describing processes in lines.
 Results. obtained results estimate irregular resistance (wave conductance) matrix considered as quadrupole. Such can be quadrupole matrix: conductance circuit This makes possible, according desired function (gain, input coefficient), allowable deviation from nominal value order select tolerance reproducing impedance. Conclusions. proposed criterion parameter deviations using norm four-pole inherently an integral used preliminarily frequency domain strongest distortions, regardless functional segment. approach applicable both heterogeneous covers
