Circuit Theory and Vizualizations
Molík, Petr ; Kaluža, Vlastimil (referee) ; Kunovský, Jiří (advisor)
This Bachelor thesis is concerned with modern method of interpretation and presentation of the Circuit theory. Clearly illustrates and with applied tests demonstrates theory, which is learned in Circuit theory subject, part of Bachelor's degree study program on Information technology on Brno University of Technology. Thesis consists of short introduction into method of visual education, main elaborated topics and description of prepared information system, which cover whole project. Thesis ends with system evaluation and usage of topics for students and references by students, they have already used described project.

Electronic RLC meter
Dvořák, Radim ; Hanák, Pavel (referee) ; Lattenberg, Ivo (advisor)
This work deals with measurement methods of passive components R, L ,C used almost in every electrical circuit. Work describes progress of choosing the right methods for measurement and also the process of designing the autonomous RLC meter with use of ATMEL microprocessor chips. The RLC meter will be powered from rechargable battery and will be able to measure primary attributes of RLC components.

Analysis of Influence of Manufacturing Technology on Utility Properties of a Reducing Valve Part
Novotný, Michal ; Sigmund, Marian (referee) ; Řiháček, Jan (advisor)
The present work is focused on the comparison of the currently used technology for the production of reducing resistors, i.e. electroerosive machining in combination with soldering on one side and the use of a suitable additive technology on the other hand. In addition to the purely technological aspects, such as the individual production processes or their preparation, economic aspects are also compared, supplemented by an assessment of the delivery times of the finished parts. The analysis is carried out The environmental impact of both production approaches is also analysed. The individual comparisons form the basis for to assess whether the replacement of the conventional manufacturing approach by additive manufacturing is advantageous in this case. The results of this assessment can then be used for future applications of the considered additive manufacturing approaches for similar components.

Soldering station
Golian, Dominik ; Baštán, Ondřej (referee) ; Macho, Tomáš (advisor)
The goal of this paper is to create a functional soldering station, which would achieve the quality of commercialy available products. The design itself will not be satisfactory without sufficient knowledge of the field. Thus the introductory chapter focuses on a quick overview of matters concerning soldering The attributes are chosen based on market research. The station is equipped with a microcontroller. This allows implementation of usefull functions of several of the compered soldering stations. The practical part contains the electrical solutions and circuit board design. The program taking care of functionality of the entire product is described next. Control structure regulating the irons temperature was selected based on system identification. The result is a product, which satisfies all the requirements.

Description Methods for Electrical Systems and Their Solving
Křižka, Jakub ; Němec, Zdeněk (referee) ; Šeda, Miloš (advisor)
The objective of bachelor thesis is a searching description of methods, which are usually used for calculation of circuit variable values in electric circuits. At the beginning is thesis concerning with description of individual components (power supplies, electronic components) used in electric circuits, then also with analysis of rules, which are the fundamental for a calculation of values in electronic circuit – Ohm’s rule and Kirchhoff’s rules. Indivisible part of thesis is also summary of special methods, such as method of loop currents (mesh analysis), method of nodal voltage (nodal analysis) etc. and their demonstration on examples of electric circuits. The structure of thesis is coursebook and gives successive summary of information in area calculations of electric circuits.

Active electrical filters based on switched-capacitor circuits
Třeček, Stanislav ; Dostál, Tomáš (referee) ; Brančík, Lubomír (advisor)
This thesis deals with concept of universal frequency filter by application of a switched-capacitor functional block. The concept is based on the theory of switched-capacitor circuits and the theory of a design of classical frequency filters. The printed circuit board was designed based on the filter connection developed by using a software Eagle. The filter was implemented as a laboratory product. This product has been revitalized and the frequency response of all types of filters has been measured. The measured parameters were compared with the parameters set out in the technical documentation of functional block.
