Abstract
Tema ovog završnog rada je realizacija aktivnog nisko propusnog filtra 4. reda s aproksimacijom po Butterworthu i Besselu. Preko zadanih prijenosnih funkcija NP filtra 4. reda s aproksimacijama po Butterworthu i Besselu dobio se matematički model i grafovi za raspored nula i polova, amplitudno-frekvencijsku karakteristiku, fazno-frekvencijsku karakteristiku, impulsni odziv, skokovni odziv i grupno kašnjenje. Nakon toga slijedilo je određivanje parametara filtra (faktor pojačanja, granična... More frekvencija, faktor kvalitete), te izračun elemenata i realizacija. Kako smo htjeli filtar za graničnu frekvenciju od 4 kHz, bilo je potrebno denormirati filtar i ponoviti postupke koje smo radili kod normirane prijenosne funkcije. Kako bi mogli provjeriti točnost izračuna filtra, koristili smo program LTspice pomoću kojega smo realizirali filtre, te smo preko simulacije dobili grafičke prikaze koje smo usporedili s grafičkim prikazima dobivenim u MATLAB-u.

Abstract (english)
The theme of this thesis is the realization of the active low-pass filter of the 4th order with approximation by Butterwort and Bessel. Mathematical model and graphs for pole and zero assignments, amplitude-frequency characteristic, phase-frequency characteristic, time response, and group delay, were obtained from 4th order filtering functions of Butterwort and Bessel. Subsequently, the filter parameters (gain factor, limit frequency, quality factor) were determined, as well as the... More calculation of the elements and the realization. As we wanted a 4kHz bandwidth filter, it was necessary to denorm the filter and repeat the procedures we did at the standard portable function. To be able to check the accuracy of the filter calculation, we used the LTspice program by which we realized the filter and by simulation we got graphs that we compared with the graphs obtained in MATLAB.
