Abstract
Razvojem digitalnih integriranih sklopova entuzijastima je omogućeno lagana gradnja uređaja odnosno implementacija funkcija koje su prije bile rezervirane za profesionalne uređaje. U ovom radu prikazana je izrada digitalne skretnice pomoću digitalnog procesora TAS3103. Uz digitalni procesor TAS3103, koji ima ulogu obrade signala za digitalnu skretnicu, implementiran je i mikrokontroler Atmega328P koji ima ulogu upraljanja radom TAS3103 digitalnog procesora i ostvarivanju korisničkog sučelja prema korisniku putem osobnog računala radi lakše kontrole nad radom TAS3103 digitalnog procesora. U sustav ulazi signal putem optičkog ulaza gdje se nakon pretvorbe u električni šalje u digitalni procesor TAS3103. Unutar digitalnog procesora TAS3103 uzima se jedan od kanala (lijevi ili desni, ovisno unutar kojeg je zvučnika ugrađen sustav) te se zatim unutar TAS3103 digitalnog procesora filtrira na niskofrekventni te visokofrekventi. Uz filtraciju signala moguće je podesiti razinu signala odnosno glasnoću zvuka te njegovo vremensko kašnjenje u odnosu jedan na drugi signal. Naposlijetku se signal u izlaznom mješalu šalje kao stereo signal no umjesto lijevog i desnog kanala imamo niskotonski i visokotonski signal. Za potrebe kontrole nad radom digitalnog procesora TAS3103 razvijeno je korisničko sučelje, implementirano na samom mikrokontroleru Atmega328P radi lakšeg pristupa s bilo kojeg osobnog računala odnosno operativnog sustava.
Abstract (english)
With the development of digital integrated circuits enthusiasts have been given the option of building devices which have functions previously reserved for professional devices. This thesis shows one way of building of digital crossover with the help of TAS3103 digital processor. Besides of TAS3103 digital processor there is an microcontroller Atmega328P which has a purpose of controlling the ATTACKS and to provide user interface for the user via personal computer. Entering the system via optical link, the signal is then turned into electrical signal and enters into TAS3103 digital processor. In TAS3103 one of the two channels(left or right, depending in what speaker is the digital crossover used) is then filtered it such a way that we get low and high frequency signal. Besides of filtering it is possible to set the volume of signal and the delay of signal in relationship whit one another. In the end signal is mixed in output mixer so that is similar to stereo signal but instead of left and right channel we have low and high frequency signal.
