USB miltimeter with microprocessor
Samek, Martin ; Kolka, Zdeněk (referee) ; Kovář, Jan (advisor)
Topic of my terminal labour is a proposion of multimeter and its resulting connection by the help of bus USB. When proposing the multimeter there was a tendency to use a minimal number of component parts to conserve a good protection against a bad usage in application. The most widespread busbar USB is used for connection of the multimeter and a computer. Standard HID is used for communication, for that it is not neccessary to install any system drivers.

Oscilloscope module with wireless data transmission
Kočík, Karol ; Svoboda, Vít (referee) ; Havlíková, Marie (advisor)
The aim of the thesis is the design and realization of the oscilloscope module with wireless data transfer. One part of the thesis is a short overview of the different types of AD converters. The main part is focused on the hardware configuration that allows modification of the wireless module of the oscilloscope, and the possibility of using in the industrial zone. The design takes into account reducing of consumption and EMC compatibility.

Measurement module with simultaneous-sampling A/D converter
Křížek, Miroslav ; Beneš, Petr (referee) ; Havránek, Zdeněk (advisor)
In this work is designed programme unit for acquisition analog acoustic signlas from sensors. There is used accurate A/D converter ADS1287 by the company Texas Iinstrument with resolution of 24 bits to digitizing these signals. There is used 32-bit microprocessor AT91SAM7S64 by the company Atmel to control this A/D converter and sending digitized data to PC. This microprocessor has implemented USB interface. By force of developmental programme units whit microprocessor and A/D converter is produced programme for microprocessor in developmental setting IAR Embedded Workbench IDE 5.0 and simple aplication for PC in setting Borland C++ Builder. Both of those programs are in language C++. Rate of sampling is 26 kHz. On the basis is realized programme unit USB-ADC whit microprocessor and A/D converter.

BER Meter for Video Signals
Šimoník, Petr ; Frýza, Tomáš (referee) ; Říčný, Václav (advisor)
The diplomma thesis is dealing with possibilities of Signal to noise ratio measurement by method, which is based on direct measurement. It is chosen the most suitable method – signal and noise separation to two different parallel signal branches, where is measured signal strength in one branch and root mean square value in the other. The thesis is consisted of a concept of detail block scheme of Signal to noise ratio meter, which was designed in terms of theoretical knowledge. Particular functional blocks were circuit-designed, the active and passive parts were chosen and their function were described. There were made simulation and displayed input and output time flows. There is designed the whole connection of engineered Signal to noise ratio meter in the last part of my thesis. The double-sided board of printed circuit is contained too. It was created simple programme for supervisor micro-processor. Thereby were constructed complete bases for realization.
