Adaptive Digital Filtering of Biological Signals
Ištok, Martin ; Kozumplík, Jiří (referee) ; Provazník, Ivo (advisor)
The main objective of this bachelor’s thesis was to describe adaptive digital filtering theory including different types of the adaptive algorithm and adaptive filter. An adaptive systém is used for power line interference canceller for ECG signal. The thesis includes design of 4 adaptive filters: simple adaptive filter, simple adaptive notch filter, adaptive notch filter using resonator and adaptive notch filter using adaptive resonator. It also contains basic testing of the filters based on different settings. Different settings are also evaluated.

Adaptive Filtering of Biological Signals
Šmíd, Karel ; Kozumplík, Jiří (referee) ; Provazník, Ivo (advisor)
Objective of this diploma work was to study methods of adaptive filtering and their use in suppression of noise in biological signals. Adaptive filtering represents effective means of suppression of parasitic nonstationary disturbances in a useful signal. The task was to design various types of adaptive filters and implement an adaptation algorithm in Matlab programming environment. It namely included suppression of powerline noise at 50 Hz and 100 Hz in ECG signals with minimization useful components disturbing. The realized filters were verified on real ECH signals and their efficiency was evaluated.
