20.500.12556/DKUM-38096 VGRAJENI SISTEM ZVOČNEGA SPEKTRALNEGA ANALIZATORJA EMBEDDED SYSTEM FOR AUDIO SPECTRUM ANALYZER V začetku diplomske naloge smo razložili osnovne pojme spektralnega analizatorja torej kaj je spekter in zakaj sploh želimo analizirati spekter nekega signala. Ker naše delo temelji na FFT spektralnem analizatorju smo v nadaljevanju podrobno opisali kako deluje hitra Fouriereva transformacija (FFT). Po opisu delovanja FFT smo nato še opisali lastnosti FFT spektralnega analizatorja in si pogledali njegovo zgradbo. Nato je sledil opis delovanja in zgradbe našega spektralnega analizatorja. Opisali smo analogno vhodno stopnjo, ki ji je sledila še digitalna obdelava signala z mikrokrmilnikom in prikaz rezultata na zaslon. Izvedene so bile tudi meritve širine in razločljivosti spektra. At the beginning of diploma thesis, we explained the basic concepts of spectrum analyzer, for example what the spectrum is and why we want to analyze the signal spectrum. Since our work is based on a FFT spectrum analyzer we followed a detail description on how does the fast Fourier transform (FFT) work. After a description of FFT we also described the features of FFT based spectrum analyzer and looked at its structure. Furthermore we explained the structure of our spectrum analyzer and how it works. We also described the analog input stage, which was followed by digital signal processing with microcontroller and the result shown on the display. We also measured the width and resolution of spectrum. vgrajeni sistem zvok analizator spekter Fouriereva transformacija embedded system sound analyzer spectrum Fourier transform true true false [G.
