Remote data acquisition systems
Svadbík, Vít ; Zeman, Václav (referee) ; Mišurec, Jiří (advisor)
This work construes usage phone lines, system GSM and GPRS, internet and communication after high - tension lead in systems of remote gathering data. With development automated running shoot up need acquisition actual indications about all sorts of quantity. Acquisition these information often action on big distance. Systems for gathering from extensive region mark like „remote data acquisition systems". In first part of this work is accentuate on possibility usage as above channels at remote deduction gauging arrangement. In second part are mentioned counts real metering carrier rate and noise narrowband communication PLC. At the close is state instance usage some circumscribed ways transmission data for meter reading electrometer in municipality Boršice u Blatnice.

Design of switching-mode audio power amplifier
Svadbík, Vít ; Sutorý, Tomáš (referee) ; Brančík, Lubomír (advisor)
This work describes the design of audio amplifiers operating in switching mode. The first part describes basic principles of the power stage switching concept. There is described differences between classes of amplifiers according to technology. The second larger part includes design and construction of the switching amplifiers. Design is implemented, including the preamplifier and power supply. Power supply works in switching mode. The measured parameters of the proposed facility are given in the last part.
