Digitally controlled filter
Rez, Jan ; Szabó, Zoltán (referee) ; Friedl, Martin (advisor)
This bachelor's thesis deals with design of a functional prototype universal digitally controlled analog frequency filter 2th order. Part of the design is the selection of appropriate filter topology diagram and selection of an integrated circuit. Universal filter will contain lowpass, highpass, bandpass and notch filter. The filter is tuned in cutoff frequency from 100 Hz to 15 kHz. The bachelor's thesis focuses on the circuit analysis of selected concrete structure of universal filter and possibilities of digital control filters. The practical part of this thesis includes PCB design, control software for filter and graphical representation of measured results.

Hardware MISO Emulator for Fading Channels
Rez, Jan ; Pítra,, Kamil (referee) ; Šebesta, Jiří (advisor)
This thesis is devoted to study the possibility of solving a hardware MISO emulator for fading channels and design of experimental device. The theoretical part starts with the theory of propagation of electromagnetic waves in a different types of environment, follows the principles and phenomena describing the radiocommunication channels and gradually gets up to specific channel models used for planning radio links. The actual design study of emulator is based on theoretical knowledge mentioned in this thesis. The basic principle of each channel model and thus so the emulator for fading channels is Tapped Delay Line model. From the point of view of the peripheral emulator solutions are designed with two topology circuits, parallel and serial-parallel. Emulator control method, mechanical arrangement, selection of topology circuit, components selection, desing of the PCB and software design is also analyzed. The results of this thesis is prototype production of experimental device and final discussion about achieved requirements and tasks.
