Ukususela kwi-Analog ukuya kwiDividal and Back
Ingaba uhlala ubambelele ngokuqinile kumdlali wakho weCD, wenze umtshini kwinqununu yentloko engenakunamandla, okanye umgangatho wakho wokuphulaphula uwela kwindawo ethile, iiposa yakho yomsindo wenqwelo yemoto mhlawumbi ixhamla kwi-car audio audio DAC yakho. guqula). Enye imvelaphi yomsakazo we-AM / FM oqhelekileyo, oqala ngomqondiso we-analog, kodwa enye imithombo yomsindo kwimoto yakho yonke igcinwe kwiifomati zedijithali-nokuba ingaba kwi-CD engokwenyama okanye njengemigqomo kunye nee -tes kwi-flash drive. Ukuze uguqule ukuba ulwazi lwedijithali kwisalathisi se-analog ekwazi ukuqhuba izithethi - kwaye ngoko udala umculo ongawuphulaphula ngokwenene - kufuneka udlule kwi-digital to converog analter.
Ngoko, ngokwenene, yi- DAC , kwaye yintoni ebaluleke ngokwenene le ngqungquthela encinci ye-teknoloji? Impendulo yombuzo wesibini kulula: i-DAC enhle ibaluleke kakhulu kwiinkqubo zomsindo weemoto zanamhlanje. Impendulo yombuzo wokuqala, nangona kunjalo, idinga okungaphezulu kancinane ngokwemigaqo.
Ukususela kwi-Analog ukuya kwiDigital and Back Again
Umculo, kunye nezinye iindlela zokurekhodwa kwee-audio, zonke ziqala njengeempawu zokubonisa, kwaye ngezinye ixesha zabhalwa kwiifom ze-analog. Iirekhodi kunye neksetekethi ze-compact zemizekelo yeefomathi ze-analog, kodwa ukurekhodwa kwee-audio okwangoku kuye kwafudukela kwindawo yedijithali - kuqala ngamaCD kwaye kamva ngeefayile ze-digital ezifana nee-MP3s .
Injongo yokugcina nokudlulisa umculo, kunye nezinye iirekhodi zokurekhoda, kwiifomenti zedijithali ngokukodwa ngumcimbi wokugcina indawo kunye nokulula. I-compact disc ingagcina idatha engaphezulu yomsindo ngaphandle kwirekhodi okanye i-cassette edibeneyo kwisithuba esingaphantsi, kunye nemidiya yokugcinwa kwedijithali njengamatshini asebenzayo kunye ne-flash drives zingagcina inani elongezelelweyo leenkcukacha zomsindo - ngendlela ye-MP3s kunye nezinye iifayile - kunoko.
Emva kokurekhoda komsindo we-analog kuye yaguqulwa yaba yidatha yedijithali, ayiyisebenzisi kangako kuthi ide iguqulwe. Ngethuba ngelifomathi yedijithali, isalathisi ibonakaliswe njengedatha yedatha engakwazi ukuqhuba isithethi okanye ukudala isandi esizwakalayo sisodwa. Ukuze wenze njalo, kufuneka idluliselwe kwi-digital converter.
Idijithali kuguqulelo lwe-Analog
Cishe zonke izixhobo zomsindo ezixhomekeke kwiidijithali zedijithali ziqukethe idijithali kumguquli we-analog. Oku kuquka konke ukusuka kwi- iPod yakho kwiyunithi yintloko. Kwimimandla yaseshashalazini yasekhaya, kukho ii-DAC eziqhelekileyo ezenzelwe ukusetyenziswa kunye nabadlali be-CD abangabandakanyi i-DAC okanye babe ne-digital output. La manqaku asemgangathweni aphezulu kakhulu kumgangatho kunamaninzi e-DAC anokwakhiwa, ngoko ke anako ukuzaliswa okuthembekileyo kweempawu zokuqala zangaphambili.
Nangona kukho iintlobo ezahlukeneyo ze-DAC, bonke benza umsebenzi ofanayo oyintloko: ukuguqula idatha engabonakali yedijithali kwisibonakaliso somzimba esinokuthi sikhuliswe kwaye sisetyenziswe ukuqhuba ii-loudspeakers. Oku kuvame ukufezekiswa ngokuguqula ulwazi lwedijithali kwisethi ehambelanayo yamapulsi ahambileyo, abuye agqitywe ngokubhaliweyo. Umgangatho wesigxina esibangelwa kukuxhomekeke kakhulu kwendlela iDAC eya ngayo malunga nokufezekisa oku, ngoko ke ulwazi olufanayo lwedijithali lunokubonelela ngekhwalithi ephilileyo ephikisanayo ngokuxhomekeka kwiDAC.
Uninzi lwamadijithali kubaguquli be-analog ziqulethwe kwiisekethe ezidibeneyo ngenxa yobukhulu nezithintelo zeendleko, kodwa nakhona ii-DAC ezisetyenziselwa ukusebenzisa iibhubhu zokucima ukuvelisa izandi ezifudumeleyo, ezongezelelweyo.
IiDAC zeDVD eziPhathwayo kunye neeNyunithi zeNtloko
I-DAC ezininzi eziphathekayo zenzelwe ukusetyenziswa kunye nee-laptops, kwaye ngokugqithiseleyo zikhupha umthwalo ophezulu wokuguqula umculo wedijithali kwisignali ye-analog kwi-software kwikhompyutha. Olu hlobo lwe-DAC oluphathekayo lunokusetyenziswa kwimoto yakho, ukuba unomthombo womsindo onokukwazi ukuvelisa nge-USB kunye neyunithi yintloko yakho ine-input analog.
Enye indlela i-DAC edlala ngayo kwimoto kukuba ezinye iinqununu zentloko zibandakanya iimpompi zedijithali, ngokuqhelekileyo kwifom ye-USB okanye i-jack yokuthengisa. Indlela enolu hlobo loxhumo lusebenza ngayo kukuvumela ukuba ufake ipowuni yakho kwi-iPhone yakho, ithebhulethi, okanye nayiphi enye i-MP3 player kwaye ulayishe i-unit unit, ngaphandle kokuxhomekeka kwi-DAC kwifowuni okanye kwenye ifowuni.
