All-pass filters with various active devices
Novotný, Jakub ; Šotner, Roman (referee) ; Petržela, Jiří (advisor)
The theme of the semester project is to provide an overview of the function and use of analogue all-pass filters. It deals with their specific implementation using active functional blocks, i. e. using LT1228 transconductance amplifier manufactured by Linear Technology, using transimpedance amplifier AD844 manufactured by Analog Devices and using negative three port second generation current conveyor EL2082 manufactured by Intersil (formerly Elantec). Further outlines the concept of laboratory exercises on all-pass filters with the aforementioned integrated circuits. The exercise will consist of three separate units.

Laboratory tutorial for MC9S08LH microcontrollers and display
Řehoř, Petr ; Richter, Miloslav (referee) ; Macho, Tomáš (advisor)
This bachelor thesis introduces microcontroller MC9S08LH64 and its modules such as analog to digital converter, internal clock source, liquid crystal display driver, serial communication interface and time of day module. It also containes some basic information about peripheries, which are on the development board TWR-S08LH64 together with the microcontroller. The peripheries are LCD display GD-5306P and accelerometer MMA7361L. Thesis continues with elaboration of five laboratory exercises in which microcontroller, LCD display, accelerometer and A/D converter are used. The description of time of day module and serial communication interface using is contained. Each of laboratory exercise contains problem description, functions of indicators and buttons, program description, flow diagram and programming technique. All the techniques are proved and lead programmer step-by-step through programming of the exercise from creating a new project to functional program. One part of the thesis describes libraries and procedures for driving A/D converter, LCD display, internal clock source, interrupts, serial communication interface and time of day module are included. Most of the procedures initialize the modules at the begining of the program. The result of this thesis is five programmed and debuged programs for microcontroller. The operating of the programs is described in flow diagrams. In addition two programs for computer, which communicate with some programs for microcontroller, was programmed. This computer programs are very easy to use and they are debuged and tested on several computers running WinXP and Win7.

New laboratory practices with bus control system Foxtrot
Matouš, Milan ; Kubec, Jindřich (referee) ; Bátora, Branislav (advisor)
The bachelors thesis deals with laboratory exercises based on wiring system created by Foxtrot Company Teco. In the first part, the work briefly introduces the reader with issues of dealing with intelligent systems for houses, properties, topology and last but not least history of such systems. The following chapter involves a characteristic information regarding the abovementioned Foxtrot system – namely composition, function and communication. In order to ensure that the laboratory exercises are feasible a construction of laboratory boards was carried out and. The next sections of the thesis involve process of construction of such laboratory boards, description of all used components and the entire budget. The laboratory exercises are created in the Mosaic software. How to initially set up the software and certain basic information regarding its properties is contained within another chapter. The uppermost parts of the thesis are two laboratory tasks. The first one solves a programming of blinds, heating, cooling and switching of wireless buttons RFox. The other laboratory task aims to create circuits for switching and dimming channels of RGB LED strips which are controlled via the website.

Simulation scenarios in IT Guru environment for Communication technology course
Rybka, Štěpán ; Hasmanda, Martin (referee) ; Jeřábek, Jan (advisor)
This thesis called Simulation scenarios in an IT Guru enviroment for Communication Technologies deals with the design of laboratory experiments for the above-mentioned subject. The first part is a theoretical introduction to the protocols. The practical part contains the tasks itself. The work includes four laboratory tasks with a detailed description of the work and an illustrative pictures. The first two tasks are focused on the application protocols, with which the user comes into contact with every day. The other two are focused on routing protocols, precisely the internal routing protocol IS-IS and BGP external routing protocol. A free version of simulation software OPNET Modeler and IT Guru enviroment version 9.1.A were used to create the work.

Laboratory exercises in OPNET environmentfor Communication technolgies course
Kasper, Robin ; Hošek, Jiří (referee) ; Jeřábek, Jan (advisor)
This master’s thesis deals with the design of laboratory exercises for the Communication Technologies course that is included in the second year of bachelor’s degree in Teleinformatics. This course represents first introduction of students with network protocols and technologies, therefore, the thesis deals with just the basic physical technologies, routing protocols and transport layer protocols. The introductory part of the thesis is devoted to theoretical knowledge to particular tasks. For the design of laboratory exercises is used OPNET environment, concretely its unpaid version IT Guru Academic Edition 9.1. The first task is focused on the differences in two basic transport protocols Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). The second task is orientated on the differences in the transmission network parameters using wireless networks and Ethernet technologies. In the third task the routing protocols Routing Information Protocol (RIP) a Open Shortest Path First (OSPF) are compared. These are protocols of a group Interior Gateway Protocol (IGP) that are characterized by the usage within a single autonomous system. The last exercise is aimed at Asynchronous Transfer Mode (ATM) and Frame Relay technologies, which are technologies used mainly in networks Wide Area Network (WAN). All devised exercises are accompanied by detailed instructions for students including supplementary questions and tasks leading to individual work and reflection. The thesis includes model solutions to these four exercises and CD where are inserted all programs source codes.
