Electronic Representation of Line Reflex
Yousifová, Hanen ; Šátek, Václav (referee) ; Kunovský, Jiří (advisor)
It would be difficult to imagine a world without communication systems . In order to optimise guided communication systems , it is necessary to determine or project power and signal losses in the system, since all systems have such losses . To determine these losses and eventually ensure a maximum output, it is necessary to formulate some kind of equation with which to calculate these losses . A mathematical derivation for the telegraph equation in terms of voltage and current for a section of a transmission line will be investigated .

Telegraph Equation
Továrek, Tomáš ; Nechvátal, Luděk (referee) ; Franců, Jan (advisor)
Telegraph equations simulate propagation of the electric signal in an electrical transmission line. This pair of partial diferential equations is derived from physical laws. Behaviour of their solution,. especially effect of impedance match of transmission line on signal distortion is studied. The results are illustrated by numerical experiments.

Multi-Conductor Model of Communication over Outdoor Power Lines
Franek, Lešek ; Steinbauer, Miloslav (referee) ; Vozňák, Miroslav (referee) ; Fiedler, Petr (advisor)
PLC - power line communication is not new. It has been known for many years. But It never be used in massive scale. There were only sporadic applications, for example ripple control system HDO used in the Czechoslovakia. PLC currently experiencing a renaissance thanks to the advent of Smart Grid. PLC offering relatively low bit rates and relatively unreliable transmission, but these disadvantages compensates very low costs to build a communication infrastructure and it offers specific functionalities for Smart Grid. The question is whether the declared parameters will be met in the real world. This thesis tries to find an answer.
