Abstract
Elektroencefalografija (electroencefalography, EEG) je neinvazivna metoda mjerenja električne moždane aktivnosti. EEG mjeri promjene napona koje su posljedica koordinirane depolarizacije i repolarizacije skupine neurona unutar mozga. Tema diplomskog rada je obrada elektroencefalografskog (EEG) signala primjenom digitalnih filtara.. U uvodnom dijelu opisani su EEG signali i njihova primjena u medicini i znanosti. U praktičnom dijelu diplomskog rada provedena je obrada EEG signala primjenom digitalnih filtara: visokopropusnog i niskopropusnog filtra. Projektirani su i primijenjeni odgovarajući filtri s konačnim odzivom (FIR) i filtri s beskonačnim odzivom (IIR). Prikazane su značajke korištenih filtara u vremenskom i frekvencijskom području. Rezultati analize potvrđuju da niskopropusni filter smanjuje valovitost na većim frekvencijama sa malim utjecajem na amplitudu u vremenskom području, a visokopropusni filter smanjuje valovitost na niskim frekvnecijama i ima veći utjecaj na amplitudu u vremenskom području.
Abstract (english)
Electroencephalograpfy (EEG) is non-invasive method of measuring electrical brain activity. EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain. Topic of this thesis is analyses of filter effects on EEG signals. In the introductory part EEG signals and their application is explained. In the practical part of this thesis EEG signals were processed with digital filters both high-pass and loww-pass filter. Filters with finite impulse response (FIR) and infinite impulse response (IIR) were designed and used. Results after analyses of the effects of filtering confirmed that low-pass filter reduces ripples at higher frequency with small alterications of amplitude in time domain while high-pass filter reduces ripples at lower frequencies with bigger alterications of amplitude in time domain.
