Web applications supporting education of audio signal processing
Malcher, Tomáš ; Mokrý, Ondřej (referee) ; Rajmic, Pavel (advisor)
This bachelors thesis deals with a creation of web applications using JavaScript language. These web applications should be helpful in signal processing classes by showing and explaining different phenomenons to students. Students can see how different parameters affect the outcome of said issue. The theory needed for understanding and implementation is covered by this thesis. Thesis covers key parts of the code of said web applications and the libraries used for their implementaition.

Web-Based Demo of Fourier Transform for Signal Processing Courses
Hyrš, Martin ; Plchot, Oldřich (referee) ; Černocký, Jan (advisor)
The aim of this work is to create a program demonstrating the Fourier transform. The introductory section summarizes the theory of Fourier transform and shows the procedure for its numerical approximation. The following chapter describes the existing applets. Subsequently, the concept of the demonstration and its implementation are described. The final part contains tutorial examples of using the application and summary of users' reactions.

Development of laboratory exercises for subject the Signals and systems analysis
Doleček, Josef ; Mucha, Ján (referee) ; Zvončák, Vojtěch (advisor)
The bachelor thesis deals with basic operation with signals and, using demonstrative applications in Matlab, it should explain these operation to CASS (Signals and Systems Analysis) students. In the theory part continuous-time signals (signals classification, periodic signals, Fourier series), complex numbers, sampling and discrete-time signals (operation of convolution and correlation) are described. Practical applications explain: square signal harmonics synthesis, two discrete-time signals convolution and cross-correlation, object distance detection by radar using cross-correlation, complex model of harmonic signal and signals sampling.

Presentation of selected themes of BSIS in PPT-environment
Havlín, Radomil ; Šebesta, Vladimír (referee) ; Sigmund, Milan (advisor)
The bachelors thesis occupy by topics of the course BSIS, which can be presented by the multimedia and animation techniques in the presentation. In the introduction, these topics are given a different method of processing. In most cases, provides a modular solution by demonstration and argued spectrum signal. The chapters describe the operation with one, two signals at the time, the properties of Fourier transform with illustrative demonstration, the correlation with convolution, kvaziperiodické signals and the last chapter the spectrum of selective signals.

The solving of ordinary differential equations by means of the infinite series method.
Dražková, Jana ; Štoudková Růžičková, Viera (referee) ; Čermák, Jan (advisor)
This bachelor's thesis is concerned with the solving of ordinary differential equations by means of the infinite series methods, in particular, the power series and the Fourier series. The aim of this thesis is to find the solution of the initial value problem for ordinary differential equations by use of the power series and compare this approach to traditional analytic methods. Further, the thesis deals with the solving of the second order linear ordinary differential equations with a periodic forcing term via the Fourier series method.

Semi-Analytical Computations
Herzallah, Ahmad Sudqi Hussein ; Kopřiva, Jan (referee) ; Kunovský, Jiří (advisor)
This thesis discusses the analytical errors emerging from semi-analytical calculations. It also discusses about the modern method of Taylor's series for numerical calculations of ordinary differential equations and chosen methods of charachterized functions. The end solutions indicate favourable results for the semi-analytical calculations in the selected roles and responsible differential equations by direct execution of Taylor's series for solutions of polynomial functions, exponential functions & geometric functions using simulation program "TKSL". It also discusses about the definite & indefinite Intergals and methods for the solution of definite integrals. Followed by a brief introduction of Maple, Matlab & TKSL and further comparison of the result of the three programs & finding the best way of resolving the definite integrals.

Practical examples of signal processing
Hanzálek, Pavel ; Smékal, Zdeněk (referee) ; Mekyska, Jiří (advisor)
The thesis focuses on the issue of signal processing. Using practical examples, it tries to show the use of individual signal processing operations from a practical point of view. For each of the selected signal processing operations, an application is created in MATLAB, including a graphical interface for easier operation. The division of the thesis is such that each chapter is first analyzed from a theoretical point of view, then it is shown using a practical demonstration of what the operation is used in practice. Individual applications are described here, mainly in terms of how they are handled and their possible results. The results of the practical part are presented in the attachment of the thesis.
