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.

Low-range high-speed optical transceiver
Pučálka, Jan ; Tošovský, Petr (referee) ; Kubíček, Michal (advisor)
The diploma thesis deals with description and design of a low-cost free-space optical (FSO) link. First, general FSO theory is discussed including their common parameters, properties and topologies. Further, optical signal sources and detectors are proposed. Finally, the selected implementation is described including its design and realization. The proposed FSO consists of two identical segments (modules) to form a full-duplex link. The FSO utilizes LED as a light source, maximum speed data rate is 100 Mb/s with 100Base-TX interface.

Programmable signal generator
Románek, Karel ; Kolka, Zdeněk (referee) ; Tošovský, Petr (advisor)
This thesis treats designing and the implementation of the Programmable Signal Generator which generates analog and digital signals using microcontroller. It describes the function of the generator, component selection and their implementation into the circuit, for example design of circuits for digital to analog conversion and the final adjustment of generated analog signals (amplification and offset setting). It also describes the communication protocol between the generator and personal computer using USB HID class, the development of graphical user interface and microcontroller firmware. Lastly, the measurement results are presented and compared with simulation results.

Design of bass guitar preamplifier
Müller, Radek ; Tošovský, Petr (referee) ; Brančík, Lubomír (advisor)
This thesis deals with analog bass guitar preamplifiers and related functional blocks such as equalizers and bass effects. The first part contains a theoretical analysis of individual functional blocks preamplifiers and principles as well as an outline of the design and construction principles. In the following section is presented a design of connection that involves a bass guitar preamplifier, including an equalizer, an integrated distortion effect and an amplifier for headphone output. The proposed connections are simulated in the PSpice program and the printed circuit boards design is carried out using the Eagle program. Based on previous results, the construction of a bass guitar preamplifier is realized. The parameters of the individual blocks are measured and compared with the simulations.

Programmable ignition system for spark-ignition engine
Friedel, Daniel ; Kubíček, Michal (referee) ; Tošovský, Petr (advisor)
This thesis is concerned with design of programmable capacitive ignition, powered from board grid. Universality of the system, especially possibility to change values of timing of early spark via changes of programme in microcontroller was taken as major goal. Microcontroller is used as the operative element of ignition. Commonly used methods for sensing of engine speed and managing of ignition are defined and explained at the begining of the thesis. Also is presented realisation of hardware and software part and draw up the methodology calibration of the speed sensor. The ignition is designed to avoid the need to intervene in the high voltage ignition system.

Wireless modular system for device control and data acquisition
Pejchal, Luboš ; Tošovský, Petr (referee) ; Kubíček, Michal (advisor)
The aim of this project is to design a cheap and simple modular wireless system. Its purpose is wireless control of remote devices and transmission of short information blocks (temperature data, status of controlled devices…). The whole system is controlled by a PC. It utilizes hybrid wireless modules for transmission of information and control of remote devices. The project shows practical usage of a digital thermometer communicating via a 1-Wire bus. A solar cell in conjunction with a DC/DC up converter is used to power low-power temperature sensor device.
