Principles and methods of recording, digital processing and interpretation of biological signals: the methodology of recording, detection and removal of artifacts, parameters of signals digitalization, parallel multi-channel processing of various biological signals, the interpretation of the strengths and weaknesses of linear and nonlinear processing methods (Fourier, wavelet, Prony's transformation estimates energy signals, similarity, estimates of complexity).
Aim of the course -
Last update: Vyšata Oldřich MUDr. Ph.D. (23.08.2013)

Students completing the course will be able to capture and process the basic biological single and multi-channel signals (ECG, EEG, blood pressure, EMG, EP, ventilation), 2D and 3D images of CT, MR, ultrasound, OCT. They will conduct experiments on Vernier equipment (measuring temperature, pressure, ECG, ventilation parameters and muscle activity) and Walter (EEG). They will be able to filter signals, estimate power spectra using FFT, wavelet analysis, parameterization similarities signals to estimate the entropy and fractal dimension of signals and images.
