Design of Reverberator for Room Acoustics Simulation
Húserka, Jozef ; Orlovský, Kristián (referee) ; Kurc, David (advisor)
This thesis deals with artificial simulation of acoustic spaces by using reverberators. Output of this document consists of four reverberation algorithms and function that evaluates objective parameters of acoustic space from impulse responses. Reverberators and script were implemented using Matlab. Graphical user interface is used to present all of the algorithms for easier usability. First chapter deals with objective parameters of acoustic spaces and the ways they are computed from impulse response. Second chapter describes various structures which are used to build reverberators. Those structures are used in third chapter in implementations of reverberators. Third chapter also compares all implemented reverberators . In last chapter experiment was made. Impulse responses of three spaces were measured and subsequently aproximated by algorithms implemented in this thesis.

Dead time LTI SISO systems approximation using generalized Laguerre functions
Zsitva, Norbert ; Tůma, Martin (referee) ; Jura, Pavel (advisor)
This final thesis deals with the approximation of time delay in time invariant systems. First, the generalized Laguerre functions and their characteristics are presented. After this, the approximation of the Dirac delta function with the help of these functions is shown. Also, the choice of the free parameters is discussed and the results are evaluated with the help of energy. In the final part of the thesis, the approximations of systems with generalized and simple Laguerre functions are compared.

Matlab Models of DC/DC Converters
Macík, Tomáš ; Cipín, Radoslav (referee) ; Pazdera, Ivo (advisor)
The Bachelor’s thesis is focused on modeling of DC/DC converters without a transformer using Matlab Simulink software. The first part is dedicated to general explanation of function of selected switch mode power supplies. The second part contains the deduction of equations for every selected switch mode power supply and design of circuit components based on required converter parameters. The models of converters have been created in Matlab Simulink using deduced equations. The models of STEP UP and STEP DOWN converters have been created also using Simscape Power Systems Toolbox and the control of current and voltage has been designed for them.
