Autonomous circuit analysis using Matlab
Zmeškal, Ladislav ; Jeřábek, Jan (referee) ; Koton, Jaroslav (advisor)
This bachelor’s thesis will deal with the creation of a description of a program for symbolic calculation of transfer function circuit, circuits, consisting of base current conveyors and admittance. In the theoretical part describes algorithmic methods analysis circuit together with the general characteristics of the current conveyor and a brief description of the program Matlab. The second part will describe the function created program, its parts, and specific examples of calculation of transfer functions. The last part of the validation of the results program created in MATLAB with the results of the SNAP program.

Analyzer of cardiac waveform
Zmeškal, Ladislav ; Říha, Kamil (referee) ; Číž, Radim (advisor)
The thesis describes design, algorithmization and realization of graphical application for recording EKG and PPG signal using LabJack UE9 tool in Matlab program, it also describes subsequent deposition of recorded signals and their processing, such as optional selection, cropping and filtering. Furthermore there are described types of filters, methods for detecting basic parameters of EKG and PPG signals and methods for detecting R waves and Systolic peaks. Based on detection of those parameters, algorithms for computing average heart rate and finding arrhythmias were designed and tested. Last part of the thesis includes an evaulation which compares values detected by designed algorithms with values from public database which includes reference annotation.
