Design and construction of a simple music synthesizer
Ondryáš, Radek ; Čudek, Pavel (referee) ; Čech, Ondřej (advisor)
This paper deals with the topic of synthesizers. The first part of the paper provides a general description of synthesizers, their history, types, and important components. The next part of this paper focuses on sound generator chip Texas Instruments SN76477, specifically it’s functionality and ways of controlling its functions. The main part of this paper is designing and creating a synthesizer around the SN76477 sound chip and creating a box for the synthesizer from laser cut plywood.

Frequency Responses
Urbánek, Radim ; Kraus, Michal (referee) ; Kunovský, Jiří (advisor)
The aim of this MSc Thesis is to create a system for automatic generation of frequency characteristics of electrical circuits. These circuits are described by differential equations. A special simulator of RLC circuit has been created and frequence response, vector diagram can be generated. This system has been mainly suggested for application in education. The process of solving differential equations is based on the Taylor method. Systems in general is the theoretical part of this project. Different definitions of systems their divission ,basic phenomenons and mathematical devices are described there. Next chapter deals with the mathematical devices for solving differential equations which makes the basis for description of phenomenons in these systems. There are also systems TKSL and TKSL/C. In the next chapter I was investigaty the analyze of vector diagrams for simple and more difficult circuits. I have found a solution for actual circuit by this technique. The last chapter is devoted to the frequency characteristics and descriptions of simulation program for generation the frequency characteristics.

Basic models of simple electric circuits and their use in physics teaching and learning
Vítková, Miriam ; Dvořáková, Irena (advisor) ; Koudelková, Věra (referee)
The bachelor's thesis focuses on simple models of electric circuits that are used in physics classes. First I selected the overview of the models from accessible sources. Subsequently I categorised them to models that are suitable for classroom demonstration and to models that are more appropriate for discussion or error analysis. For a basic overview of models that are currently used in physics classes I created an online questionnaire and also interviewed several teachers of physics.I discovered that although there are various simple models of electric circuits available, not all of them would be suitable for classroom demonstration without subsequent discussion about possible errors. I also found out that there are teachers who like to use models of electric circuits in their classes whereas others avoid them because of the risk of students' misinterpretation.

Development of application for single boarded computer
DUDA, Ondřej
The topic of this thesis is programming of a single boarded computer called Arduino UNO. The goal is to program controlling software for this board with the usage of digital and analog accessories and to assemble an electrical circle. The theoretical part of the thesis deals with the theory of single boarded computers, wirless comunnication especially Bluetooth technology, programming language C# and integrated development environment Visual Studio. The main goal of the practical part is to create an electrical circle which contains the single boarded computer, two step motors, and a wireless Bluetooth. Another goal is to create an application for a smartphone (Windows Phone 8.1) which could wirelessly control step motors via Bluetooth. Windows Phone aplication is written in C# language. Arduino program is written in Arduino language based on C language.

Electronic kit in the subject Practical activities
ŠMRHA, Jiří
In this thesis I focused on the evaluation of the historical development of electronic kits in the Czech school system, and the survey of the current state of use of electronic kits in the subject Praktické činnosti (Practical Activities) on the second level of primary schools. The thesis also presents a comparison of different types of electronic kits using complex eva-luation criteria. Another part deals with design and implementation of a custom electronic kit intended for teaching the subject Praktické činnosti (Practical Activities), including the implementation of appropriate didactic instruction.

Innovated set for demonstrative experiments from electronics
VAŠÍČEK, Petr
The first part of this thesis is focused on the advantages of using the experiments during the physics education and their educational values. Furthermore, some types of experiments, their correct metodology of implementation and some other aspects which should be given an appropriate attention by the teacher are theoretically described. Then, some types of demonstrational sets and their brief history are described. The attention is aimed at the demonstrational set of DIDAKTIK, its content and composition. One chapter is devoted to the research of schools equipment for using the demonstrational experiments of electricity and magnetism and their evaluations. The last part deals with some experiments which can be made within this set, their documentation and evaluation. Further, there were worksheets created for some of these experiments. Two of these sheets were used among primary schools for didactic exploring and the reasults were evaluated.
