The thesis is focused on modeling, simulations and experimental verification of structures where relation between response and driving signal contains derivation or integration of non-integer order (so-called fractional structures or circuits). The task is also to design of suitable application possibilities of fractional order circuits, e.g. frequency filters, reconfigurable filters and tunable oscillators. Attention should be kept also on other ways how to implement fractional order circuits, e.g. implementation of structures with distributed parameters (RC-EDP).

The work is focused on the feature analysis of current-mode electronic frequency filters. The aim is to design algoritmizable methods that lead to finding features of filters generally defined by the schematic. It will be necessary to evaluate the available feature ranges, e.g. quality, pass-band current transfer, dynamic range within a defined supply voltage, sensitivity, etc. In the case of finding the quality range, the point is to find the extremes of a multi-variable non-linear function. Mathematical tools (e.g. Maple or MathCAD) will first be used for this purpose; afterwards the algorithm itself will be designed. Requirements to be met by the candidate: algorithm thinking, the knowledge of computer programming and circuit theory.

The thesis focuses on modern optical networks for next generation. FTTx networks in general include both active and passive access networks (FTTH - Fiber to the house, FTTB - Fiber to the building, etc.), but also networks such as FTTA or FTTO which involve ending of the optical fiber close to the antenna or to the office. All FTTx topologies are constantly evolving due to the increasing needs of users. Network optimization should cover the use of modulation formats, the issue of dispersions, or the possibility to use multiple technologies on a single fiber without their interaction.

In an object-based audio system, the different sound elements are bundled with metadata to form audio objects. This metadata then describes how the sound element should be reproduced to the listener, by defining its position in the 3D field, regardless the sound reinforcement system. Currently there are a number of approaches for positioning the audio objects, particularly ambisonics, VBAP, DirAC, and wavefield synthesis. Each of them has its advantages and disadvantages. The aim of this doctoral thesis is to analyze the possibilities of using these methods in real installations and to design and test new algorithms for positioning audio objects in 3D space.
Modern computational systems (CPU, GPU, APU, and DSP) can make use of a number of parallel computation units. The application of parallelization has now been standardized through OpenCL, which allows parallel programming of heterogeneous systems. At the same time, simulation environments (such as Matlab and Simulink) are also provided with the possibility of parallel programming. To begin with, it is necessary to make an analysis of the possibilities offered by the current standards for process parallelization that can be applied to the basic and advanced methods of digital signal processing. The aim of the dissertation is to propose algorithms for digital signal processing methods that will exploit the possibilities of parallel programming both in the course of simulation and in the final implementation for the target computational system.
