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 .

Speech Enhancement Methods
Kukučka, Peter ; Mekyska, Jiří (referee) ; Hudec, Antonín (advisor)
Aim of this work is summarize some single-channel methods of speech enhancement. These methods are explained in this work: Basic Spectral Subtraction Method, Modified Spectral Subtraction, Multi-band Spectral subtraction, spectral subtraction MMSE and Wiener filtering. All methods are implemented. Preprocessing, voice activity detector and speech scores are explained in this paper, too.
