Searching of metallic cables using geolocation systems and locator
Flídr, René ; Čučka, Milan (referee) ; Filka, Miloslav (advisor)
Subject of this work is a laboratory excersise, in which student will be going through a training polygon in an FEKT VUT area. Outcome of this work is going to be a mobile application, serving as a navigation and controll tool for students. They will be searching for control points of interests with copper lines under the ground. Then they will get information from theese lines with the help of copper lines searcher. Students should learn methods to search and localize copper lines as well as extracting data from them with the help of geolocalization andcopper lines searcher.

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.

Properties of the physical layer of ZigBee
Humpolík, Tomáš ; Frýza, Tomáš (referee) ; Prokopec, Jan (advisor)
The ZigBee standart works on using physical and data link layer of IEEE 802.15.4 standart. Three bands were defined (2.4GHz, 915MHz and 868MHz). There was also number of physical layers defined, each of them using one of the three bands and number of modulation and spreading functions. This thesis is focused first of all on specification 2,4GHz physical layer, which is world-wide used because this band can be used (with observace of the local rules) without license. Thesis is in its first part focused on modulation function, as well on used spreading functions and number of channels for each physical layer. In the second part is paid attention to demonstration kit by ATMEL Corporation, which enables associate a simple network in star topology and using the network for demonstration of simple functions of associated devices, and kit by Radiocrafts corporation, which is used in laboratory work. Laboratory work is focused on characteristics measurement during data transfer.

Construction and Realisation of Function Generator and its Application
CHALOUPEK, Pavel
This work contains problems of generators of a waveform signal. There is described a principle of a generator of a waveform signal, its circuits, its principle, a signal shaping, and its eventual utilization. Then there is created a design of a circuit of a realized generator and subsequently a practical realization of the generator of a waveform signal, its construction, its activation, its setting up and a measuring of output parameters. In conclusion there is mentioned an utilization of the realized generator in a laboratory work and an application of this work including a setting and a resolution of the laboratory work for pupils of secondary schools.
