Abstract
Živčani sustav predstavlja jedan od važnijih sustava u ljudskom tijelu te je njegovo zdravlje od iznimne važnosti za normalno funkcioniranje ljudskog organizma. U ispitivanju funkcionalnosti živčanog sustava, te kao najučestalija i najbolja metoda otkrivanja epilepsije, koristi se elektroencefalograf (EEG), koji mjeri napone mozga pomoću elektroda koje su postavljene na glavu ispitanika. Rezultat ispitivanja pomoću EEG-a naziva se elektroencefalogram te predstavlja snimku moždanih valova. Elektroencefalogram može biti narušen uslijed raznih smetnji. Kako bi se učinak smetnji otklonio ili ublažio koriste se različita pojačala koja se spajaju u kaskadu. Blok shema pojačala sastoji se od dijelova kroz koje je potrebno proći kako bi se uklonile sve smetnje i kako bi se pojačao signal potreban za formiranje rezultata. Dijelovi blok sheme pojačala su: RFI filtar, instrumentacijsko pojačalo, visokopropusni filtar, neinvertirajuće pojačalo, niskopropusni filtar, programabilno pojačalo, nakon čega slijedi analogno-digitalna pretvorba, koja rezultira nastankom digitalnog signala.
Abstract (english)
The nervous system is one of the most important systems in the human body and its health is crucial for the normal functioning of the human body. In examining the functionality of the nervous system, as well as the most common and best method of discovering epilepsy, electroencephalograph (EEG) is used, which measures the voltage of the brain by means of electrodes that are placed on the patient's head. The result of tests using EEG is called electroencephalogram whose function is to record brain waves. Electroencephalogram may be disrupted due to various disturbances. To minimize or alleviate the impact of interference, the different amplifiers that are connected in cascade are used. A block scheme of the amplifier consists of the parts that signal needs to go through in order to eliminate all interference and to enhance the signal required for the formation of the results. Parts of the block scheme of the amplifier are: RFI filter, instrumentation amplifier, high-pass filter, non-inverting amplifier, low pass filter, a programmable amplifier, followed by an analog-to-digital conversion, resulting in the emergence of the digital signal.
