Update of laboratory exercises for the course Analysis of Signals and Systems
Chrástek, Jakub ; Liska, Matej (referee) ; Krajsa, Ondřej (advisor)
My work focuses on updating selected laboratory exercises for the course Analysis of Signals and Systems. In the first half of the theoretical part, the basic concepts and subdivisions of frequency filters and their overview in terms of design type, transmitted bandwidth and approximations are presented. In the second half of the theoretical part of the thesis, basic information on aliasing is given. The practical part of the thesis focuses on calculating and optimising the values of the selected parameters. These parameters are simulated in OrCAD Capture CIS. The design part presents the source design and 3D PCB models in Fusion 360.

Design of LED lighting for industrial camera systems
Svoboda, Martin ; Honec, Peter (referee) ; Janáková, Ilona (advisor)
The bachelor thesis deals with the development, design and construction of multispectral lighting for industrial camera systems. The lighting is conceived as a modular device consisting of two parts - a control unit, which can be communicated primarily through the Modbus TCP / IP protocol, which powers, controls and collects information about the connected lighting unit. The illumination unit is equipped with 64 intelligent RGBW light emitting diodes located in an 8x8 matrix and one control diode opposite to which light intensity sensors are placed to give feedback on the color and intensity of the light. There are two temperature sensors located between the LEDs to check the temperature of the lighting unit. Both units are housed in a robust aluminum chassis. The control unit contains a microcomputer programmed in C language

Wireless Signal Transmission of DMX512 Interface
Polóni, Pavol ; Jaroš, Jiří (referee) ; Šimek, Václav (advisor)
Master's thesis deals with design and implementation of a system for wireless transmission of DMX signal 512, which is primarily designed for the management of lighting effects. Its electrical specification is based on the EIA485 standard. Text of the work describes the design stage. First is the issue of implied actual protocol DMX 512 or EIA485. Next sign on selecting a suitable architecture for wireless transmission, management and compilation of the block diagrams. Describes the operation of the component selection and circuit implementation of the scheme, which is using the DPS Eagle compiled. In conclusion, this work is to evaluate the results of the proposed system and showing the way to its further development so that it can be realistically implemented in practice.

The Design of Enlargement of Sensor and Control Module of Mobile Robots Named Brontes
Husar, Jan ; Kopečný, Lukáš (referee) ; Florián, Tomáš (advisor)
This bachelor's thesis deals with the proposal of the sensory module and the control of mobile robots named Brontes enlargement. For this purpose a printed circuit board named MX05 was created, which extends its functionality via connection to the control board named LTR001.2. Construction of the board was conducted on the bases of the needs and requirements coming from robot peripherals. The proposal was created containing the control, protection and filtering features. Further, the board was realized and inhabited. Using MX05 creates a great simplification of wiring and there is implied the extension of the original features that are useful not only in robots Brontes.
