History of audio carriers and transmission of sound
Šimarová, Lucie ; Krhutová, Milena (referee) ; Šedrlová, Magdalena (advisor)
Cílem této bakalářské práce je popsat vývoj zvukových nosičů. Tato bakalářská práce poskytuje náhled do historie a současnosti zvukových nosičů. Nejprve seznamuje čtenáře s teorií přenosu zvuku. Tato část je zaměřena na přenos vlnění a popisuje rozdíly mezi vlnami. Následně jsou probírány analogové a digitální způsoby záznamu zvuku. Hlavní část práce se věnuje uchovávání hudby. Nejprve se práce zabývá uchováním hudby před mechanickým záznamem, tato část zahrnuje notaci, tabulatury a automatofony. V další části je již popsán mechanický záznam zvuku, a to v analogové formě. Poslední kapitola je zaměřena na digitální záznam zvuku. V neposlední řadě práce obeznamuje čtenáře s kulturním a hudebním vlivem jednotlivých nosičů. Znalosti jsou nabyty z různých zdrojů, především z literatury.

New laboratory tasks for the course "Programmable logic controllers"
Chaňo, Patrik ; Zuth, Daniel (referee) ; Marada, Tomáš (advisor)
The goal of this work is to suggest and realize new assignments for the course "Programmable logic controllers" that are aimed at logic modules LOGO! made by the Siemens company. The first part contains the theoretical introduction of the LogoSoft! Comfort program and the overview of all used block functions. The second part of this work is dedicated to a set of tasks to solve, sorted according to the used functions, and difficulty.

Guitar tube preamplifier with digitally controlled presets
Malinčík, Ondrej ; Pavlík, Michal (referee) ; Háze, Jiří (advisor)
Aim of this work is design of guitar tube preamplifier which tone corrections and gain control is controlled electronicaly using digital potentiometers with ability to saving these values to memory. This work analyses and discuss used circuitry in design and presents demonstration of possible replacement of mechanical potenciometer with digital one in the conclusion.

Universal BLDC motor controller
Pijáček, Ondřej ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
This thesis describes the design of universal control unit for BLDC motor powered from airplane power distribution system of 28 V capable of driving motor up to 10 A. The maximal engine power is about 250 W. Important prerequisite is possibility of driving various motor size without needs of changing wiring board using only the configuration in the auxiliary memory unit. To control different motors is enough one unit with one program without any way to interfere to the unit itself.

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.

Sun Sensor for I2C bus
Hodáňová, Adéla ; Povalač, Aleš (referee) ; Urbanec, Tomáš (advisor)
This thesis contains design of sun sensor. At first, it deals with different types of sensors, after which it focuses on selection of mode for connecting the sensor. After measuring all parameters, this thesis focus is determining of diode configuration in space. Next part of the thesis is choice of suitable microprocessor and its support circuits. Thesis ends with construction of the sun sensor and testing of sensor’s parameters.

Autopsy
Hofmann, Petr Eric ; Záhora, Zdeněk (referee) ; Vaněk, Vojtěch (advisor)
This bachelor thesis is focused on digital games, namely the creation of game objects and virtual space. An existing room was used as the main object, which was the auditorium at FFA. The outcome of this project is a computer app bringing users the possibility to explore the digital model of the auditorium. The digital technologies are providing us with a completely different point of view regarding the already existing room. The video game's interactive principles allow us to look closer at the image layers, called textures, responsible for the final look of a game object. The emphasis of this project is to communicate mainly with the help of visual language which will reduce the need for greater amount of textual information towards the user. The content can be unlocked by navigation through an intuitive user interface, an ingame tool to control the play. The title "Autopsy" was chosen as an allegory to the process of finding and gaining new information and experience thanks to the dismantling of a researched subject just to its main core. The autopsy room is not just a room, where the action happens, it is the action itself.
