Educational board for STM processors
Očenášek, Matěj ; Novák, Lukáš (referee) ; Šteffan, Pavel (advisor)
This work deals with design of educational board for STM32 microcontrollers. This educational board contains basic types of peripherals such as OLED display, EEPROM, LED or seven segment displays. The theoretical part focuses on the description of the STM32F303 processor and the Nucleo-64 development board on which the processor is installed. It describes in particular its properties. In the theoretical part, besides the STM32F303 processor, the individual parts of the educational board are described. The practical part deals with the design of the block diagram, the scheme and the design of the printed circuit board.

Resistance saw
Kalčík, Petr ; Minárik, Vladimír (referee) ; Procházka, Petr (advisor)
This work is focused on the design and construction of component parts of resistance saw. Mechanical parts consist of a movable bracket and a taut cutting wire of Constantan. Electrical parts are designed to supply and control temperature of the cutting wire. The current intensity in the cutting wire is compared with the required current intensity. The difference of these two measurements is fed into a PI - controller. The next part is a PWM generator which generates the square wave signal. The pulse ratio of this signal is proportional to the required temperature of the cutting wire. This signal switches a switching converter that consists of a power transistor P-MOSFET IRF5210 and a diode MBR20100CT. Choking coil with a ferrite E core and with the cutting wire is connected to the output of the converter.

Design of audio power amplifier with Bluetooth connectivity
Bartoň, Jan ; Šotner, Roman (referee) ; Brančík, Lubomír (advisor)
This bachelor‘s thesis deals with the task of designing an audio amplifier, operating in class D, with a nominal output power of 2 x 80 W with Bluetooth connectivity, supplemented by an equalizer and a state display. A power supply and a user interface are designed as well. At first, research regarding audio amplifiers is made, followed by a more thorough description of class D operating principles. Afterwards the actual synthesis of the desired amplifier is presented, followed by the power supply design procedure. The correctness of the synthesis is later verified by simulations in PSpice and LTSpice. Theoretical design is then practically built, and its parameters are confronted with expected values by measurements.

Digital audio amplifier with universal inputs
Svadbík, Pavel ; Stifter,, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This diploma thesis deals with digital audio amplifier with universal inputs and its design. The first part describes modulation and audio formats for audio electronics. The thesis contain design of a block diagram of the digital audio amplifier and describes the requirements for functional blocks. As a basic device for audio signal processing was choosen integrated circuit STA326. The thesis continue with circuits design for each blocks with a description of their principles. The next section describes the construction and firmware for microcontroller. The last part of this diploma thesis is targeted on the presentation of the measured parameters of the amplifier. The conclusion summarizes the results that have been achieved and advantages and disadvantages of the digital audio amplifier prototype.

Multiple Object Tracking
Takács, Ákos ; Drahanský, Martin (referee) ; Rozman, Jaroslav (advisor)
This paper is focusing on technical specification, concept and implementation of multiple object tracking with using a standard web camera. Image data processing has been done through the OpanCV library. The system is able to rotate the camera, in order to have the chosen target in the center of the screen. FITkit controller has been used to control the camera. The software has been implemented in the C++ environment.
