Abstract

U diplomskom radu izračunate su karakteristike niskopropusnih antialiasing filtara 2., 3. i 4. reda, graničnih frekvencija 1 kHz i 2.5 kHz. Koristeći Control Design and Simulation Module, koji se nalazi u sklopu programskog paketa LabVIEW, izrađeni su matematički modeli navedenih filtara pomoću kojih su filtri simulirani. Naposlijetku su ispitani stvarni filtri, isključivo 3. reda, koristeći piezoakcelerometre instalirane na elektrodinamičkom vibratoru. Snimljene su njihove frekvencijske karakteristike koristeći višekanalni analizator signala i programsku aplikaciju u LabVIEW-u koja je prethodno programirana. Rezultati ispitivanja filtara su zadovoljavajući.

Abstract (english)

In the thesis are calculated 2nd, 3rd and 4th order low-pass antialiasing filters characterictics, with limit frequencies of 1 kHz and 2.5 kHz. Using Control Design and Simulation Module, which is located within software package LabVIEW, mathematical models of said filters through which the filters are simulated are made. Ultimately were examined real filters, exclusively 3rd order, using piezoelectric accelerometer installed on electrodynamic vibrator. Their frequency characterictics were recorded using a multichannel signal analyzer and software application in LabVIEW that was previously programmed. The filters test results are satisfactory.
