Design and realization of a new laboratory exercise with PLC B&R Automation
Cejpek, Zdeněk ; Němec, Zdeněk (referee) ; Lang, Stanislav (advisor)
This bachelor thesis is concerned with designing of a laboratory task primary dedicated for the course „Advanced control methods“, which for the education uses the instruments of company B&R Automation. From possible aproaches chooses modeling of dynamic systems using analog electrical circuits. Those circuits are realized in modular manner, in order to allow building models of various systems. The thesis also includes a desing of proper casing, which simplifies the manipulation by building of the systems. Using designed prototype modules, a model of a separately excited DC motor was built. This model is used for realization of the laboratory task, for which is provided a short manual including some basic program for Automation Studio. The thesis also briefly introduces the company B&R, it´s products and a PLC configuration used in courses „Advanced control methods“.

Selective Circuits - Laboratory Experiment
Košťál, Stanislav ; Vágner, Petr (referee) ; Urbanec, Tomáš (advisor)
The aim of this thesis is to describe the distribution and behavior of selective circuits and methods for their implementation. There are formulas provided for the calculation of the frequency components of selected second-order RLC filters. It further describes the choice of filter frequency components and computing relationships needed for the construction of coils. The work also includes a description and complete information needed for making measurements of the measurement of the RLC band-pass. The annex to this work includes all the materials needed for implementation of laboratory tasks designed to measure using the product.

OTDR optical path analyzer
Šimková, Barbora ; Tomašov, Adrián (referee) ; Dejdar, Petr (advisor)
The aim of this master's thesis was a theoretical analysis of OTDR issues, analysis of OTDR device components, as well as basic parameters of this device. The thesis also includes a theoretical analysis of reflections, scattering, and various types of connectors. In the practical part, a circuit design for OTDR measurement was developed and subsequently implemented. The circuit was realized using the Red Pitaya development board and Koheron laser. Additionally, a circuit for direct method measurement was also created. In the LabView development environment, a program was created, including a graphical user interface. A laboratory task was also designed to provide a basic understanding of OTDR measurement issues.

Measurement of passive frequency crossovers for loudspeaker systems
Holínský, Jan ; Hanák, Pavel (referee) ; Balík, Miroslav (advisor)
The content of the master´s thesis is to approach the issue of measuring the characteristics of passive frequency crossover. The work describes individual types of measured characteristics and their possibility of measurement. Then the work describes design of modules for measurement characteristics of passive frequency crossover (shunt, resistive load and amplifier). These modules were made and tested for its functions. For the amplifier is then made a second design for fulfilment requirements. The second version isn’t made in this work. At the end of the work was prepared the theoretical part of the laboratory task: Measurement of characteristics of passive frequency crossover, including protocol.

Modular Active Crossover Network - Laboratory Tool
Holínský, Jan ; Hanák, Pavel (referee) ; Balík, Miroslav (advisor)
This thesis is about design of active frequency crossovers and their implementation. The work analyses particular types of circuits used in active frequency crossovers, especially circuits used for laboratory device. Then the work describes design of printed circuit boards (PCB) for the designed circuits and construction of modules for the laboratory device, when the compatibility and modularity is important for all active frequency crossovers arts. These modules are made and testing its functions. In this thesis is disassembled final proposal laboratory device and laboratory device is realized. The design and measurement of the characteristics of active frequency crossovers and correction circuits is processed in the form of a laboratory tasks.
