Update of laboratory exercises for the course Analysis of Signals and Systems
Chrástek, Jakub ; Liska, Matej (referee) ; Krajsa, Ondřej (advisor)
My work focuses on updating selected laboratory exercises for the course Analysis of Signals and Systems. In the first half of the theoretical part, the basic concepts and subdivisions of frequency filters and their overview in terms of design type, transmitted bandwidth and approximations are presented. In the second half of the theoretical part of the thesis, basic information on aliasing is given. The practical part of the thesis focuses on calculating and optimising the values of the selected parameters. These parameters are simulated in OrCAD Capture CIS. The design part presents the source design and 3D PCB models in Fusion 360.

Web application for planar filter design
Sýkora, Vlastimil ; Kadlec, Petr (referee) ; Raida, Zbyněk (advisor)
This bachelor thesis deals with the development of web application for the design of planar filters. The application is written in Python. The thesis was aimed to create a script for simplified filter synthesis, based on the type of filter, its order, and chosen approximation. Initially, an equivalent circuit is constructed and a planar implementation for a given microwave substrate is proposes. The first part of the thesis is devoted to the brief theory required for the design of a simple planar circuit. The second part of this thesis deals with the development of the application itself. The function of input and ouput blocks is described here. The second part also includes description of computational scripts, including examples of the source code, for each filter type, where a different design method is used with a brief additional theory. The third part contains the design of four prototype filters of different types, their simulation in Ansys HFSS, and evaluation of obtained results.

Textile Microwave Components
Hotovec, Jakub ; Láčík, Jaroslav (referee) ; Vašina, Petr (advisor)
This bachelor thesis is focused on possibilities of designing components integrated on substrate, where substrate is fabric. It contains theoretical information about the SIW structure, measurement of dieletric parameters of three fabrics, design, synthesis and production of waveguide, a three port divider and a band-pass filter on three substrates. For simulation CST Microwave Studio is used

Analysis of the electronic circuits using Mathcad program
Šimůnek, Martin ; Vochyán, Josef (referee) ; Petržela, Jiří (advisor)
The main idea of this thesis is a propose by designing filters in Mathcad program. This paper deals with a basic principle in filters design and these principles are implemented into the Mathcad program. In the introductory part is described aproximation which was used in Mathcad script. In the other parts of this project is described program which was created on designed filters.

Pseudo-differential Filter Using DDCCs
Sládok, Ondřej
This article describes a pseudo-differential second-order filter, using three differential difference current conveyors (DDCCs) and five passive elements. The proposed structure is able to realize all types of frequency responses. The circuit has a high input impedance, low active and passive sensitivity and high common-mode rejection ratio (CMRR).
