QRS detection using zero crossing counting
Hylmar, Petr ; Janoušek, Oto (referee) ; Vítek, Martin (advisor)
This master's thesis describes basics principles of QRS complex detection. It is focused on QRS detection using zero crossing counts method. There are described princips and program realization of this method. The other part is focused on genetic optimalization algorithm. There are presented obtained optimalization results on standard CSE and MIT-BIH database. The quality of the detector is compared with other authors. The optimalized QRS detector achieves comparable results with other authors. The part of the thesis is graphical user interface which supply view on modified ECG signal and detection results.

Sampling Rate Conversion
Hylmar, Petr ; Vítek, Martin (referee) ; Kozumplík, Jiří (advisor)
This thesis is focused on sampling rate conversion by a rational factor interpolation and decimation and sampling rate coversion by an arbitrary factor interpolation and decimation. There are described methods sampling rate conversion in time domain based on lowpass FIR linear filter and in spectral domain based on zero spectral lines. These methods are created in Matlab programming and tested on particular example. The results of this thesis are sensible parameter lowpass FIR linear filter for sampling rate conversion and discussion success rate used methods.
