20.500.12556/DKUM-90668 Spektralni analizator avdio signala Audio signal spectrum analyser V diplomskem delu so predstavljeni razvoj, načrtovanje in izdelava analognega spektralnega analizatorja avdio signala. V grobem vezje sestavljajo aktivni pasovnoprepustni filtri drugega reda, detektorji vršne napetosti, logični del vezja, ki skrbi za pošiljanje signalov na prava mesta, ter zadnji, četrti del, ki je sestav prikazovalnikov in so končna enota vezja. Frekvenčni razpon analizatorja sega od 20 Hz do 20 kHz. Koraki med pasovi so odvisni od njihovega števila, v našem primeru pa celoten frekvenčni spekter delimo na 16 pasov. V delu najprej po segmentih predstavimo dele vezja, ki jih najprej teoretično obrazložimo, navedemo morebitne izračune in določevanje komponent ter predstavimo sheme ter tiskanine. Sledijo meritve in ugotovitve. Kljub možnim izboljšavam vezje deluje v skladu z zastavljenimi cilji. The thesis presents the development, planning and production of an analog spectrum analyzer of an audio signal. The rough circuit consists of band-pass filters of the second order filter, peak detectors, the logical part of the link, which takes care of sending signals to the right places, and the last, fourth part, which is the composition of the displays and is the final unit of the link. The frequency range of the analyzer is from 20 Hz to 20 kHz. The steps between the bands depend on the number of them, and in our case the entire frequency spectrum is divided into 16 steps. In the task, we first present a part of the connection by segments, which we first explain theoretically, indicate possible calculations and determination of components, and present schemes and printed materials. Measurements and findings follow. Despite the possible improvements, the circuit works according to the set goals. avdio signal spektralna analiza pasovnoprepustni filter detektor vršne napetosti preklopna vezja stolpčni prikazovalnik audio signal spectral analisys band-pass filter peak detector switching circuits column display true true false [A.
