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.

Blockchain technology and its use
Hrbotický, Lukáš ; Sikora, Marek (referee) ; Zeman, Václav (advisor)
This diploma theses concerns the matter of blockchain technology and its practical use, especially for nonfinancial services. Theoretical part describes the blockchain technology from the technological and juridical point of view and examples of its practical use are also mentioned. In the practical part two laboratory exercises were designed for further familiarization of the blockchain technology, in which students try some real applications on their own.

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.

Laboratory exercises in Riverbed Modeler simulation environment
Lojek, Stanislav ; Bečková, Zuzana (referee) ; Langhammer, Lukáš (advisor)
This semestral thesis deals with the creation of a laboratory exercise for the course of Communication Technology. This course is designed for Teleinformatics in bachelor's degree program and should provide students with basic knowledge of network protocols and technologies. For this reason, the thesis deals with basic transport protocols, protocols for transmission via backbone networks and network layer protocols. The introductory part introduces the OPNET design environment, more precisely its free version of Riverbed Modeler Academic Edition 17.5, where the design of the laboratory exercises is done. The second part is a necessary theory to the exercises. The lab exercise is focused on differences in TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) protocols. The second laboratory exercises is focused on technologies for transmission mainly on WAN (Wide Area Network) namely ATM (Asynchronous Transfer Mode) and Frame Relay. The last proposed exercises deals with the two most prominent Internet protocols that are used for communications IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6) protocols. Guides for students have been created for this task, and at the end of each part, the complementary tasks and questions are given to students in oder to test the gained knowledge of the discussed issues.

Wireless model 802.11 in NS2
Botta, Miroslav ; Kubánková, Anna (referee) ; Šimek, Milan (advisor)
Theme of this work is simple wireless simulation Network Simulation 2 tool. The work consists of more parts. In the first section is basic theory about Wi-Fi networks, they types and standards and describes how useful can it be in practical life. In the second section there is a short annotation for programming in TCL language and possibilities of NS2 for simulating wireless networks. In the end there is a complex simulation of this network. In the third part there are two complex tasks where the information’s are drawn from the previous two parts.

Laboratory model "Liquid Tanks" innovation
Škapa, Antonín ; Fiedler, Petr (referee) ; Kaczmarczyk, Václav (advisor)
This bachelor thesis deals with innovation of laboratory exercise „Tanks“. There are described the most used sensors and actuators including means of connection to PLC. The ANSI/ISA S88 and ANSI/ISA S95 standards are depicted as well with emphasis on key performace indicators. Technological tanks are documented here including industrial use examples since the laboratory exercise „tanks“ works with model of a technological tank. Furthermore there are briefly analyzed PLC programming languages, especially SCL. In the end, there is the laboratory exercise assigment with technological scheme and attention of error states.
