Abstract
Ovim se završnim radom proučava modulacija signala preko Matlaba i analiza mjerenjem u laboratoriju. Signali se generiraju programski i šalju u obliku Excel dokumenta na program Ultra Station. Nakon postavljanja određenih parametara signali se šalju na funkcijski generator i analiziraju preko osciloskopa u vremenskoj domeni i spektralnog analizatora u frekvencijskoj domeni. Glavni problem je način na koji se signali generiraju i mogu analizirati bez problema. U ovom je slučaju korišten... More programski paket Matlab zbog mogućnosti generiranja složenih signala na jednostavan način. Svaki modulirani signal dijeli sličnu Matlab skriptu uz malu promjenu. Signali se analiziraju na način da se za pojedini signal odredi frekvencija i amplituda. Potrebno je dokazati tvrdnju da parametri odgovaraju onima koji su korišteni prilikom generiranja signala u Matlabu. Kod frekvencijske domene frekvencijski spektri signala prikazuju se na spektralnom analizatoru. Rezultati mjerenja vrijednosti na različitim frekvencijama uspoređuju se s onima koji se dobiju u idealnim uvjetima preko Matlaba (proračun). Na taj se način može prikazati da vanjski čimbenici i šum mogu utjecati na rezultate analize signala u laboratoriju. Less
Abstract (english)
This paper focuses on generating pseuod-random modulated signals with Matlab and their analysis in a laboratory. Signals are generated with software and are sent as an Excel type document to Ultra Station. By setting adequate parameters, signals are sent to the function generator and analyzed with an oscilloscope in time domain and spectral analyzer in frequency domain. The main problem is how the signal is generated and analyzed without a problem. In this case Matlab is used by... More generating the signals with a Matlab script because of the efficiency in making complex signals much easier. All the modulated signals share quite the same Matlab script considering some slight changes how the modulation is executed in some signals. Signal are analyzed by measuring their frequency and Amplitude in time domain. It is important to see that the parameters on the Oscilloscope are identical to the ones used for generating the signals in the Matlab script. In frequency domain frequency spectrums of signals are shown on the spectrum analyzer. Results by measuring amplitudes of frequency components are compared to results obtained by using the Matlab software in ideal conditions. It is possible that noise and other outside factors can have an effect on results obtained by measuring in a laboratory. Less
