Wavelet Filtering of ECG Signals
Staša, Josef ; Kolář, Radim (referee) ; Kozumplík, Jiří (advisor)
The aim of this project is introduction to problems about filtering of signals using wavelet transform. This method is very effective and in present it is often exploited. The main imposition is to use wavelet transform for filtering of ECG signals. Practical part of my project is realized wiener filtering based on DTWT in MATLAB software, to show advantages, disadvantages and compare linear filtering .

Narrow-Band Filters for ECG Signals
Strouhal, Adam ; Provazník, Ivo (referee) ; Kozumplík, Jiří (advisor)
The aim of this paper is to filter out the most common type of noise in EKG signals, network brum and drift. This paper deals with the design and implementation of linear filters of type FIR and IIR in Matlab. The implementation of FIR and IIR filters make use of four different design methods.

ECG Signal Wavelet Filtering
Zahradník, Radek ; Kozumplík, Jiří (referee) ; Smital, Lukáš (advisor)
The aim of this work is introduction to problems about the wavelet transform and then to use this transformation to filter ECG signal disturbed with myopotentials. The first part of this thesis contains basic information about the measurement, waveform and disturbance of ECG signal. The next part describes the method of wavelet transform and its use for the signal filtering The last part describes the practical part of work, where the results of filtering with different filter settings are evaluated, especially the various types of thresholding. At the end of this part is a comparison of results from wavelet and linear filter.

Removing Methods of Power Line Interference In ECG Signals
Herodes, J.
The paper deal with the efficiency of digital linear filtration of 12 types FIR and IIR filters used for removing power line interference from ECG signals. For testing was used database of CSE signals, containing 3750 ECG. Comparing of methods was programed in Matlab, the language of technical computing.
