Digitally controlled filter
Rez, Jan ; Szabó, Zoltán (referee) ; Friedl, Martin (advisor)
This bachelor's thesis deals with design of a functional prototype universal digitally controlled analog frequency filter 2th order. Part of the design is the selection of appropriate filter topology diagram and selection of an integrated circuit. Universal filter will contain lowpass, highpass, bandpass and notch filter. The filter is tuned in cutoff frequency from 100 Hz to 15 kHz. The bachelor's thesis focuses on the circuit analysis of selected concrete structure of universal filter and possibilities of digital control filters. The practical part of this thesis includes PCB design, control software for filter and graphical representation of measured results.

Laboratory kit for design work with Altera CPLD devices
Gajdošík, Petr ; obrany, Petr Bojda, Univerzita (referee) ; Kolouch, Jaromír (advisor)
In this thesis I aim at a design of the laboratory kit and study ways how to programme CPLD devices made by Altera company. The product is used for development and demonstration of applications in CPLD devices made by Altera company. The kit is designed for Altera programming cables and Presto (made by ASIX). Input signals are implemented by a set of switches and buttons on the board. Output states are displayed by LED diods, possibly connected to multiplex the display. The user can connect to external devices via external inputs. Thesis is also aimed at the design PCB of the laboratory kit, subsequent production, recovery and verification of compatibility ALTERA and PRESTO programmers. End of the thesis aims on working with the Quartus II design environment. In particular, it is a guide to working with templates and simulation of VHDL designs.

Communication between FPGA and computer - USB high speed
Kollár, Tomáš ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
This bachelors thesis is about a possible interconnection method of FPGA (Field-Programmable Gate Array) chips with the PC through the USB 2.0 bus. These programmable arrays are very important nowadays mainly because of their high speed and high flexibility. Such properties make possible to use FPGAs in applications that require small data bandwidth and also which can utilize the whole bandwidth offered by the USB 2.0 bus. This thesis deals with possibility to use such transfer rate and its short description followed by the design of PCB layout. As the communication between the FPGA and the PC is made possible with the help of a microcontroller capable of handling such requests, I decided to include a short description of its functionality and working principle description in the thesis. The last part describes the communication through the GPIF interface for high-speed transfers.

Radio Telemetry for RC Aircrafts
Žák, Tomáš ; Fuchs,, Michal (referee) ; Povalač, Aleš (advisor)
Master‘s thesis is focused on problematic about state of RC plane model during the flight. Device is able to measure overload, height, position, pressure and velocity of the flight and store this measurement data to memory medium. The main aim of the master‘s thesis was to design a functional board, firmware for device and design simple program for evaluating of measured data. Involvement consists of five basic parts. First part is microcontroller, which processes measurement data and communicate with others parts. Next is accelerometer. Accelerometer is used for scanning overload of the plane. Barometer is used for measurement of height and pressure. For measuring position and velocity is used GPS module. Last part is memory medium. MicroSD is used as memory medium for storing measurement data. Evaluation of measured data is realized as simple program with base graphical user interface. Program was created in Matlab.

Laboratory kit for experimental work with CoolRunner devices
Gajdošík, Petr ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
This bachelor´s thesis deals with the programming of the CPLD device from the CoolRunner.II family, made by Xilinx company, through the use of USB bus. This bus and its application is an integral part of many devices nowadays. These programmable devices are used very often, mainly because of their speed and flexibility. They can be used in many different applications. The main task is to design a laboratory kit containing input switches, outputs of signaling LED diods and a 7segments display. Next possibility is to connect it with a chance plug in many external inputs and outputs. The thesis contains some examples of programs in the VHDL language.

Programming of PLD devices using microprocessors
Petrilak, Michal ; Fedra, Zbyněk (referee) ; Kubíček, Michal (advisor)
This work is focused on configuring of Xiling's FPGA devices by embedded microcontroller. Several methods of configuration are described and the most suitable method is chosen. The attention is also paid to choose the microcontroller and auxiliary hardware components. The last part of the work describes the creation of the software for the microcontroller and for the PC. The suggested device should serve as an inexpensive substitute for commercial programmers from Xilinx.
