Modélisation des distorsions non-linéaires générées par les amplificateurs de télédistribution par câble : étude de dispositifs de compensation

Abstract : This document presents some mathematical models which allow us to observe the non-linear distorsions created by CATV networks amplifiers. These models are : the Volterra model, the Price model and three models that use an approximation of the amplifier's transfert function. A comparative study, non-linear measurements made with three types of amplifier are used. Another part of this study is realized with a cascade of three identical amplifiers. A private appendix proposes solutions to reduce the non-linear distorsions generated by a cascade of amplifiers
