Abstract
U ovom diplomskom radu realiziran je nisko propusni filtar 4. reda Butterworthovom aproksimacijom s dva operacijska pojačala za dvije strukture – kaskadna i kaskada bikvarta. Provedena je frekvencijska i vremenska analiza filtra za normirane vrijednosti, te se onda prijenosna funkcija denormirala na graničnu frekvenciju od 3,4 kHz. Realizacija filtra izvršena je prvo za kaskadnu strukturu, pa zatim i za kaskadu bikvarta. Analizirana je Schoefflerova osjetljivost obije realizacije. Provedeni proračuni i grafovi izrađeni su u programskom paketu Matlab. Kao jedna od provjera napravljena je simulacija u programskom paketu LTSpice. Izrada tiskane pločice napravljena je u programskom paketu KiCad. Za kraj napravljena su laboratorijska mjerenja u kojima se potvrdila ispravnost modeliranog NP filtra pomoću osciloskopa i mrežnog analizatora.
Abstract (english)
In this thesis, a low-pass 4th order filter was realized by the Butterworth approximation with two operational amplifiers for two structures - cascade and biquart cascade. Frequency and time analysis of the filter for normalized values was performed, and then the transfer function was denormed to the cutoff frequency of 3.4 kHz. The filter realization was performed first for the cascade structure, and then for the biquart cascade. The Schoeffler sensitivity of both realizations was analyzed. The performed calculations and graphs were made in the MATLAB software package. As one of the checks, a simulation was made in the LTSpice software package. The production of the printed circuit board was made in the KiCad software package. Finally, laboratory measurements were made in which the correctness of the modeled NP filter was confirmed using an oscilloscope and a network analyzer.
