Abstract

This thesis is focused on classification and description of selected filtration techniques which are designed to suppress the most frequent types of fetal electrocardiogram interference. The purpose of fetal electrocardiogram recording is to achieve a full-fledged record for assessment of fetal health and mostly for correct diagnosis of hypoxic states. The aim of this study therefore is to design and realize a software which would be usable for preprocessing and would enable further signal analysis. The FIR and IIR filters and wavelet transform were used as a solution. The design of the software is described in the practical part of this thesis. For operating the program, a graphical user interface was created. There, it is possible to simulate basic types of interference, to choose a filter, and to set individual parameters for the filtering.
