Árva, Gábor ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
This project deals with the design of a transmitter in a wireless microphone system, which connects to a microphone through an XLR connector. It contains detailed description of the individual blocks, which are necessary for processing and transmitting the signal received from the microphone. It discusses methods of frequency modulation using a phase locked loop and compares their advantages and disadvantages. As the last, it deals with the antenna selection and its shrinking methods.

Castle Zdounky - conservation and restoration in the area
Franková, Tereza ; Kolouch, Jiří (referee) ; Hrabec, Josef (advisor)
The aim of the present thesis is to carry out an architectural study for the reconstruction of the chateau complex Zdounky, located near Kroměříž in Litenčiče Downs. The chateau complex covers the area of ca. 9 hectares and consists of a four-wing chateau, a Baroque granary, a new farm building with an old orchard, and a large landscape park in the English style with a number of small-scale buildings such as a greenhouse, an ice house and other valuable and remarkable natural sites, for instance an old lime tree alley or a restored animal park. The proposal complies with the intention of the current owners, i.e. to use the complex as a centre for environmental education of the youth and to make it available to the general public with an interest in nature and ecology. Therefore, the main goal of the study has been to find an optimal urban-architectural solution in order to preserve the historic value of the buildings and at the same time allow the possibility of using them for their new purposes. The concept of the reconstruction is influence by the correspondence of the surrounding landscape, the place’s history, the historic value of the individual buildings and the morphology of the terrain. The whole complex is organized in order to give the impression of unity where all the functions are connected in a logical way. It was the division of the complex into public, semi-public and private zones that represented the main guideline for the present plan. The design of the reconstructed chateau includes the semi-public and private zones - it comprises both the educational centre with accommodation as well as the owners’ residence surrounded by a private garden. The Baroque granary is reconstructed and used as a museum. Additionally, a new orangery is added and its facilities used for a cider house (in the form of a small café) where local production commodities are sold. Both of these are open to the general public as well as the chateau park. Furthermore, the design includes a trail around the chateau. For the purposes of the present thesis, it was necessary to find and redraw the old plans, verify and document their true condition and measure the Baroque granary, whose documentation was completely missing.

SIMULATION AND IMPLEMENTATION ANALYSIS OF THE AUTOSYNCHRONOUS SUBSYSTEMS IN VLSI DEVICE
Kováč, Michal ; Kostka,, František (referee) ; Jalovecký, Rudolf (referee) ; Kolouch, Jaromír (advisor)
This thesis focuses on problem-solution analysis of synchronous digital circuits; the results of which are autosynchronous circuit design methodology, timing parameter definitions based on simulation models and constraint settings. The RTL transformation of the synchronous state machine in VHDL language to an autosynchronous state machine was created with minimal modifications for the simple design of these circuits. Following this, a comparison of the transformed state machines with their synchronous originals in parameters such as chip area, current consumption and timing specification domain is introduced. The summation of this thesis displays a theoretical comparison of several types of synchronization (synchronous, autosynchronous, fundamental asynchronous, EAIC, Bundled-data, Dual-rail) which are presented on the single state machine example with the same technology parameters.

Adjustable source feeded and controlled by USB bus
Staněk, Miroslav ; Frýza, Tomáš (referee) ; Kolouch, Jaromír (advisor)
The aim of this bachelor’s thesis is concept and realization of voltage source which is controlled and feeded by Universal Serial Bus. There will be presented whole design, execution, development progress and finalization of this project in the following text. This source must boost and buck standard voltage from USB. So it will be necessary using two source lines. Microcontroller of AVR family will be used in the direct part of this adjustable source. Into this microcontroller will be embedded USB interface by the software solution. The microcontroller isn‘t used only for communication with PC by the computer programme, but it is also used for switching the source lines by the PWM modulation. According to the minimum output voltage scale (0 – 15 V) this source is useful for a wide spectrum of low- power devices. This equipment could be helpful together with laptop to charging devices (cell phone, camera, pocket osciloscope etc.), which are carried with notebook for doing outdoor activities and measurements.

Accumulator diagnostic bus interface
Chytka, František ; Kolouch, Jaromír (referee) ; Kolouch, Jaromír (advisor)
The thesis deals with design and construction of diagnostic device for batteries. In the analysis I described and compared well known I2C bus and quite similar SMBus. The latter bus is used in the laptop batteries called Smart Battery. The design includes the USB bus, which I described briefly in analysis too. I suggested a several designs, discuss them and build the best one of them. The realization of the diagnostic device includes construction aspect and programing aspect. Both aspects are described in the thesis. At last, the results of test diagnostic of several batteries carried out by designed device are introduced.

Microprocessor controlled testing unit
Mejzlík, Vladimír ; Tošovský, Petr (referee) ; Kolouch, Jaromír (advisor)
This project deals with the design of an autonomous microprocessor controlled testing unit for automatic controlling the output of the tested device, depending on the excitation of its inputs. There are possible realizations of testing unit hardware functional blocks described. Possible options are objectively analyzed in accord with the project specification and with regard to the mutual compatibility of individual blocks, availability, price and desired functionality. The most appropriate selected solution is implemented using the specific circuit elements. The output of the project is realized functional testing unit and elaborated product documentation. There was control software for the microprocessor of the unit written. The software implements an interpreter for the test algorithm execution, carries out the test evaluation and stores a record of the test process to the file. There was also the utility for a PC, which allows uploading tests to the testing unit via USB created.

Signal and data logger
Borsányi, Tamás ; Vyskočil, Pavel (referee) ; Kolouch, Jaromír (advisor)
The goal of this project is to design a signal and data logger, which captures analog and digital signals with very long record time. The device supports multichannel complex triggering, a real-time oscilloscope-like mode and an offline mode for analyzing of previously sampled data. This project contains detailed analysis of the topic, description of hardware and software solutions and used methods. The thesis also contains verification tests and measurements. This device will be mainly used for hardware debugging of microprocessor based applications.

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.
