Modelling of the properties of transmission channel for xDSL systems
 Nepovím, Pavel ; Číž, Radim (referee) ; Krajsa, Ondřej (advisor)
The aim of the thesis is introduce problems of the modelling transmission properties of the metallic symetric cables that are always the most often transmission cables on access networks where the xDSL systems are installed. At first the structual features of the metallic symetric cables, theirs transmission properties (primary and secondary) and models of these parametres are shown. Then the ABCD transmission parameters that characterized the transmission line as a two-port network are described, by force of that the transfer function is obtained. The aplication which was created in Matlab offers to check of the theoretical knowledges . This aplication makes it possible to choose the character of transmission line and to approximate the obtained transfer function of this transmission line.
