Fractional-Octave Analysis of Acoustic Signals
Ryšavý, Marek ; Frenštátský, Petr (referee) ; Schimmel, Jiří (advisor)
The diploma thesis is focused on design and optimalization of digital octave and fraction-octave band filters. This thesis describe the behavior of filters in systems with fixed point arithmetics and investigate the impact of quantization coefficients for frequency response of filter. Filters, whitch has been designed, are implemented into simple software in C. Designed filters are in accordance with standard IEC 61260.

Automatic Computation Control
Opálka, Jan ; Šátek, Václav (referee) ; Kunovský, Jiří (advisor)
This work deals with the automatic control of numerical calculations. The reader is acquainted with the numerical solution of differential equations and the parallel, serial, and series-parallel numerical integrator. The practical aim of this work is to design control circuits for the three mentioned variants of integrators. The design includes the development of a software simulator of the control circuit for the series-parallel integrator in a fixed point.

Loading and Printing ASCII Numbers in FPGA
Závodník, Tomáš ; Zachariášová, Marcela (referee) ; Bartoš, Václav (advisor)
The topic of this work is the issue of processing decimal numbers using binary hardware units. Making use of specialized hardware for this purpose is problematic due to both number systems being incompatible. The thesis is focused specifically on fixed point decimal numbers passed in the form of ASCII character strings and on the FPGA technology. The proposed solution lies in creating hardware units that allow sequential loading and printing of decimal numbers in the mentioned form digit by digit. In terms of the content of this work, it introduces suitable algorithms and describes the realization of the proposed units. It results in their efficient, configurable, portable and reusable implementation.

Audio equalizer implementation based on FPGA structure
Otisk, Libor ; Valach, Soběslav (referee) ; Kváš, Marek (advisor)
The bachelor thesis introduces the basic types of audio equalizers. It describes the design of digital filters for graphic equalizer, the correct choice of structure, placement and shape of digital filters. It also describes the implementation of graphic equalizer in the fixed-point arithmetic. It further describes an implementation of the algorithm graphic equalizer on PC and the implementation in gate array of FPGA.

FPGA implementation of artificial neural network
Čermák, Justin ; Šteffan, Pavel (referee) ; Bohrn, Marek (advisor)
This master's thesis describes the design of effective working artificial neural network in FPGA Virtex-5 series with the maximum use of the possibility of parallelization. The theoretical part contains basic information on artificial neural networks, FPGA and VHDL. The practical part describes the used format of the variables, creating non-linear function, the principle of calculation the single layers, or the possibility of parameter settings generated artificial neural networks.
