Abstract

Uzorkovanje signala jedan je od osnovnih koraka pri digitalizaciji signala. Uzorkovanjem se omogućuje obrada signala na računalu u digitalnom obliku, te prikaz tog istog signala. Cilj projekta ostvarenjem programskog sučelja u LabVIEW-u izmjeriti i odrediti fazni pomak između dva sinusna signala generirana iz kalibratore, te poslana na uzorkovanje. Mjerenje se vrši u dva slučaja za dvije različite kartice, jednostavniju i napredniju, te za svaku po dva puta, jednom kada su signali istofazni, a drugi put kada su signali protufazni. Nakon mjerenja potrebno je analizirati dobivene rezultate, te pomoću njih utvrditi ispravnost mjerenja, kartica i samog kalibratora kao generatora sinusnog signala.

Abstract (english)

Signal sampling is one of the main steps in signal digitalization. Sampling is used to display and alter signals on computer in digital form. Purpose of this project is to measure and determinate phase difference of two sine waves by programming user interface in LabVIEW for that. Sine waves are generated by calibrator and sent to DAQs ( data acquisition devices) and then processed by LabVIEW virtual instrument. There are two separate measurements, for each of two DAQs, differentiated by phase difference. In first measurement generated sine waves have 0° phase difference and in second measurement that difference totals 180°. After measurements, gathered results are processed and correctly interpreted to determine if measured instruments are valid.
