Radar sensors for speed measurements
Doležal, Tomáš ; PhD, Jaroslav Čechák, (referee) ; Kokolia, Martin (advisor)
The main topic of this bachelor thesis is selecting a suitable microwave sensor for measuring the speed of vehicles in regular traffic, while covering multiple road lanes by a suitable method. Furthermore, the optimal one is selected in the form of search, based on the necessary parameters from commercially available radar sensors measuring primary speed. In the next step, simulation is performed for the selected speed sensor in the MATLAB environment, depending on its parameters and the modes in which it can work. The simulation also includes environmental influences on the received signal. There is introduced programmed graphical user interface for simulating a lot of situations on the road for two cars in the next section. Last section summarizes results of real measurement.

Frequency-to-Voltage Converter
Šindelář, Michal ; Bejček, Ludvík (referee) ; Beneš, Petr (advisor)
This bachelor’s thesis deals with the issue of the transfer frequency to voltage focusing on dynamics and accuracy. The goal of this thesis is the design and implementation of the converter based on the input arguments. The graph evaluates the tradeoff between dynamics and accuracy. It is possible to choose a more suitable solution to transfer frequency to voltage for the specified requirements.

Demonstration set for basic keying techniques
Žlebek, Lukáš ; Šilhavý, Pavel (referee) ; Číž, Radim (advisor)
This thesis concerns itself with construction of a set of laboratory products, used for demonstrating the basic methods of digital modulation. The primary product, is a generator of carrier and keying signals, which generates cyclically repeated data, and a carrier signal. Another two products are ASK and BPSK modulators. The theoretical part of this thesis describes a basic summary of different kinds of modulation and the design of all the product prototypes themselves. The practical part proves the functionality of individual components of the generator and the functionality of the modulators. In the last part of this thesis, there is a proposal of the laboratory task and its sample solution.
