Yiyiphi i-DAC kwaye Yintoni eSebenziselwa yona?
I-DAC, okanye umguquli wedijithali kuya ku-analog, uguqula izibonakaliso zedijithali kwiimpawu ze-analog. Ii-DAC zakhiwe kubadlali beCD kunye neDVD, kunye nezinye izixhobo zomsindo. I-DAC inomnye wemisebenzi ebaluleke kakhulu kumgangatho ozwakalayo: idala isalathisi se-analog kwiimfutho zedijithali ezigcinwe kwi-disc kunye nokuchaneka kwayo kubeka umgangatho ozwakalayo womculo esiwuva.
Yiyiphi i-DAC yangaphandle kunye Yintoni eSebenziselwa yona?
I-DAC yangaphandle yinkalo ehlukeneyo engakhiwanga kumdlali onokusetyenziswa kwamathambo amaninzi, ama-gamers kunye nabasebenzisi bekhompyutha. Ukusetyenziswa okuqhelekileyo kwe-DAC yangaphandle kukuphucula ii-DAC kwiCD okanye i-DVD player. I-teknoloji yedijithali iyashintsha rhoqo kwaye nangomdlali oneminyaka emihlanu ubudala okanye i-CD player ene-DAC eziye zabona ukuphucuka ukususela ngaloo xesha. Ukongeza i-DAC yangaphandle ihlaziya umdlali ngaphandle kokuyifakela, yandisa ubomi bayo obuncedo. Ezinye izinto ze-DAC yangaphandle ziquka ukuphucula umsindo womculo ogcinwe kwi-PC okanye kwi-Mac okanye ukuphucula umgangatho ophezulu wemidlalo yevidiyo. Ngamafutshane, yindlela efanelekileyo yokuphucula umgangatho wezandi ezininzi kwimithombo yomsindo ngaphandle kokufaka endaweni yazo.
Ziziphi iinzuzo zeDAC yangaphandle?
Inzuzo eyintloko ye-DAC yangaphandle yinto esemgangathweni. Umgangatho womculo wokuguqula isignali yedijithali kwi-analog ixhomeke kakhulu kwizinga elincinci, isampuli yesampula, izihlunu zedijithali kunye nezinye iinkqubo zekhompyutha. I-DAC ekhethekileyo yenzelwe ukusetyenziswa komculo ophezulu. Ii-DAC ziphuculwe ngonyaka kunyaka kunye nee-DAC ezidlulileyo, ezinjengezo ezifumaneka kuma-CD asekudala kunye ne-DVD abadlali abakwenziyo kunye namanqaku amasha. I-odiyo yekhompyutheni nayo inenzuzo kwi-DAC yangaphandle kuba ii-DAC ezakhiweyo kwiikhomputha ngokuqhelekileyo azikho umgangatho ophezulu.
Izixhobo ukujonga kwi-DAC zangaphandle
- Ukupakisha: I-diski ye-CD equlethwe ngumculo wedijithali egcinwe kwi-b-16 bits of resolution kunye nesampulu kwi-44.1 kHz. I-bit bit / 44.1 kHz yaziwa njengeCD Redbook, umgangatho weshishini. Uninzi lwe-DAC lwangaphandle lube ne-upsampling, into ephucula umgangatho womculo. Ngokomzekelo, isisombululo si-24-bit and sampling senziwa ngo-192 kHz. Ulwahluko lomgangatho ozwakalayo lubandakanya impendulo ephindaphindiweyo kunye nebala eliphezulu.
- Ukunciphisa i-Jitter: I-Jitter ngumcimbi wedijithali ochaphazela ixesha lokujikeleza kwe-digital. Ngamanye amaxesha kuchazwa ngokuthi 'ukutshatyalaliswa kweengcingo' kwaye ukuba ukulawulwa okanye ukupheliswa kunokuphucula umgangatho ophezulu. Uninzi lwe-DAC luqesha uhlobo lokunciphisa i-jitter.
- Iziphumo ezininzi: Ezinye ii-DAC zangaphandle zinezixhobo zedijithali enye kwaye ezinye zineziphumo ezimbini zecandelo elinye. Inzuzo yeziphumo ezimbini zidibanisa imithombo emibini, njengomdlali weCD kunye ne-PC ngexesha elinye.
- Izixhobo ze-USB: ezininzi ze-DAC zangaphandle ziquka ukufakelwa kwe-USB ukuvumela ukuveliswa komsindo wekhompyutha ukuxhuma kwi-DAC. I-DAC yangaphandle iphakamisa umgangatho ozwakalayo wemithombo yomsindo wekhompyutha.
