Tester audio cables
Boštík, Ondřej ; Friedl, Martin (referee) ; Havlíková, Marie (advisor)
This thesis deals with the theoretical knowledge necessary to draft tester audio cables. The first section provides an overview of commercially available devices designed for testing audio cables. The second part is an overview of test cables and connectors, inclu- ding their practical application and its parameters. Next chapter presents development platform Arduino. The last chapter presents tester’s design including a description of its implementation and animation.

Miniaturization and Range Extension of W-DMX v1.0 Module
Rojček, Martin ; Jaroš, Jiří (referee) ; Šimek, Václav (advisor)
The aim of this master thesis is to design a wireless system which would be primarily used for a control of stage lighting. Our idea is to establish wireless links, that will carry DMX512 protocol, between individual lighting devices based on wireless transceiver nRF2401A. The foundation of our project comes from a previous design, which was not completely suitable for a practical use because of its rather large proportions and a short RF range. The project resolves the issue of relatively short range coverage through the deployment of RF amplifier RF5722. In the same tme, it also takes into account other technical aspects such as the use of antenas with a higher gain, front-end circuits or increased transmission reliability through frequency hopping scheme. Proper attention is also given to a minimalization of the module dimensions by using SMD components and layout adjustements, so it would be possible to place the whole board inside XLR connector. Set of printed circuit boards with the specified characteristics, which is the expected outcome of our project, were designed with Eagle PCB design environment.

Measurement cables and connectors for audio
HAVEL, František
This thesis deals with design and practical implementation of a comprehensive test for measuring and comparing the performance of audio cables and connectors used in audio technology. The theoretical work is the part that deals with the signal, sound, cables and connectors and methods of measurement used. In the practical part are results and comparison of wide price range instrumental cable. Studied parameters are: the electrical resistance of the cable, the capacity and inductance. Was also been studied the affect of the cable using frequency analysis. It was created overview table, which summarizes the findings.
