Power line transfer function generator

Abstract

This bachelor's thesis deals with data communication over powerline (PLC). It describes the PLC technology, its basic division, the current opportunity to use, the sources of interference and the types of modulation. It analyzes the basic parameters of transmission line by means of which it is possible to create the equivalent transmission line model in two different ways either the mathematical model with multipath propagation or by using two-port with cascade parameters. The practical part contains measurement transfer function on different topologies. The measured values are compared with the numerical models. Furthermore, the transfer function generator was created which simulates the properties real distribution network
