Identification of the parameters of an electroencephalographic recording system
Svozilová, Veronika ; Sekora, Jiří (oponent) ; Mézl, Martin (vedoucí práce)
Electroencephalographic recording system is used to examine a brain activity. Based on this examination we can establish the diagnosis of certain diseases, such as epilepsy. The purpose of this study has been the signal processing and a signal generation which were compared with the real signal. Artificially generated signal is based on Jansen‘s mathematical model which has been also implemented in MATLAB and then that model has been extended to more complex model including nonlinearities and model electrode – electrolyte. Also a signal measurements on EEG phantom and identification of the parameters of these signals were performed. Firstly a simply signals were tested and the identification of their parameters has served to validate the EEG phantom. Secondly the created signal designed by Jansen model were tested also. Besides an analysis of all signals includes the time frequency analysis or a superposition principle testing.
