Abstract
U ovom radu rješavao se problem projektiranja jednokanalnog EKG pojačala. Projektirao se prema ulaznim zahtjevima prema kojima je predviđeno napajanje pojačala baterijom nominalnog napona 3,7 V, mora imati 2 načina rada: dijagnostički (0,05 – 120 Hz) i monitoriranje (1 – 45 Hz), a ulazni filtar mora biti niskopropusni. Kao ulazni filtar odabran je niskopropusni RC filtar. Nakon pojačanja u instrumentacijskom pojačalu, guše se niske frekvencije u Besselovom visokopropusnom filtru. Na kraju se signal dodatno pojačava u neinvertirajućem pojačalu. Dobiveno je pojačalo karakteristika bliskih zahtijevanim. Izmjeren je EKG na ispitaniku pri čemu je dobiven očekivani signal na izlazu.
Abstract (english)
This thesis is based on a problem of designing a single – channel electrocardiogram. Its design is based on given specifications which include 3,7 V single power supply, low – pass filter in its input stage and ability to work in two different modes chosen by the user: diagnosting mode (0,05 – 120 Hz) and monitoring mode (1 – 45 Hz). The chosen input stage filter is low – pass RC filter. After amplifying the signal in an instrumentation amplifier, low frequencies are attenuated in a high – pass Bessel filter. Finally, the signal is amplified in a non – inverting amplifier. As a result, the designed ECG amplifier was confirmed to have very close specifications to the ones requested. Finally, ECG was measured on a test subject which resulted in expected output signals.
