Abstract
Tema završnog rada je analizator spektra, mjerni uređaj koji prikazuje frekvencijsku domenu signala. U frekvencijskoj domeni signala su razloţene komponete po amplitudi i frekvenciji. Matematička povezanost vremenske domene signala i frekvencijke domene signala je u FFT. Osnovne vrste analizatora spektra su: superheterodinski analizator spektra, analizator spektra FFT, analizator spektra sa bankom filtra.Temeljni princip Superheterodinskog analizatora spektra signala je u mješanju ulaznog signala i signala s lokalnog oscilatora, analizator spektra s bankom filtra koristi velik broj filtra i FFT anaizator spektra koristi fourierovu transformaciju za analizu spektra signala. I na kraju smo objasnili značajke analizatora spektra na temelju kojih odabiremo prikladan analizator spektra.

Parallel abstract (English)
The topic of this graduation work is a spectrum analyzer, a measuring device showing the frequency domain. In the frequency domain, the splitted components contain different amplitude and frequency. The mathematical connection of the time domain and the frequency domain is in the FFT. The basic types of spectrum analyzer are: superheterodynamic spectrum analyzer, FFT spectrum analyzer, real-time spectrum analyzer. The principle of superheterodyne spectrum analyzer is to mix the input signal and the signal from local oscillator , real-time spectrum analyzer uses a large number of filters and FFT spectrum analyzer uses fourier transformation for spectrum analysis. Finally, we have explained the specifications of spectrum analyzer, based on we choose a suitable spectrum analyzer.
