Isixhobo Sakho Sinquma ukuthi yini okufanele ukuyisebenzise
Amakhodi we-coaxial and optical asetshenziselwa ukwenza ukuxhumeka komsindo emkhatsini wemithombo efana ne-CD noma i-DVD player, i-turntable noma umdlali wezokuxhumana, nesinye isici esinjenge-amplifier, receiver, noma isikhulumi. Zombili izinhlobo zekhebula zidlulisela isignali yedijithali kusuka kwesinye isinye kuya kwesinye.
Uma unethuba lokusebenzisa noma yiluphi uhlobo lwekhebula, ungase ube nesifiso mayelana nezici eziyingqayizivele ngayinye nokuthi yikuphi okungcono kunenhloso yakho. Impendulo ingahlukahluka kuye ngokuthi ubani oyicelayo, kodwa abantu abaningi bayavuma ukuthi umehluko wokusebenza ngokuvamile awunaki. Ngesithakazelo sokwenza ukuthi ukwazi ukwenza izinqumo ezinolwazi, nansi amaqiniso mayelana nokuxhumana kwekhebula le-coaxial ne- optical digital .
Ama-Cadio Digital Audio Cables
Ikhebula le-coaxial (noma i-coax) lisebenza kanzima usebenzisa ucingo lwethusi oluvikelwe, ngokuvamile olwenzelwe ukuba lukhuni kakhulu. Ukuphela kwekhebula le-coaxial kusetshenziswa ama- RCA ajwayelekile, athembekile futhi ahlale eqinile. Kodwa-ke, izintambo ze-coaxial zingase zifinyelele ku-RFI (ukuphazamiseka komsakazo) noma i-EMI (ukuphazanyiswa kwe-electromagnetic). Uma kunoma yiziphi izinkinga ezikhona 'hum' noma 'buzz' ngaphakathi kwesistimu, njenge- loop yomhlaba ), ikhebula le-coaxial lingadlulisela lo msindo phakathi kwezingxenye. Amakhodi we-coaxial aziwa ukuthi alahlekelwe amandla wesignali emakhilomitha amade - ngokuvamile akukhathazi umsebenzisi osekhaya.
Amakhodi E-Digital Audio Asebenzayo
Ikhebula elibonakalayo (eyaziwa nangokuthi i-Toslink) lidlulisela izimpawu zomsindo ngokukhanya okubomvu okwenziwe nge-glass noma iplastiki fiber optic medium. Isignali ehamba ngekhebula kusuka emthonjeni kumele kuqala iguqulwe kusuka isignali kagesi kuya kwelinye optical. Uma isibonakaliso sifinyelela kumamukeli, sibhekene nokuguqulwa emuva kwisignali kagesi futhi. Ngokungafani ne-coax, izintambo ze-optical azitholakali ku-RFI noma nge-EMI umsindo noma ukulahleka kwesignali ngamabanga, ngoba ukukhanya hhayi ugesi kuthwala ulwazi. Noma kunjalo, izintambo ze-optical zivame ukuba zibuthakathaka kunezihlobo zabo ze-coax, ngakho-ke kufanele banakekelwe ukuze baqiniseke ukuthi abathinteki noma bavinjiwe. Imikhawulo yekhebula elikhanyayo isebenzisa isixhumi esingaqondakali esingaqondakali okufanele sifakwe ngendlela efanele, futhi ukuxhumeka ngokuvamile akuyona njengesivinini noma okuphephile njengengxube ye-RCA yekhebula coaxial.
Zikhethele
Isinqumo sokuthi iyiphi ikhebula lokuthenga cishe kuyobe isekelwe kohlobo lokuxhumeka olutholakala ku-elekthronikhi embuzweni. Akuzona zonke izingxenye zomsindo ezingasebenzisa zombili izintambo ezibonakalayo nezama-coaxial. Abanye abasebenzisi baphikisana nalokho okuthandayo kwe-coaxial over optical, ngenxa yokucatshangelwa ngcono kwekhwalithi yomsindo jikelele. Ngenkathi ukuhlukana okunjalo kungase kube khona, umphumela kungenzeka ubuqili futhi uhlonishwe kuphela ngama-high-end systems, uma lokho. Uma nje izintambo ngokwazo zenziwe kahle, kufanele uthole ukuhluka okuncane kokusebenza phakathi kwalezi zinhlobo ezimbili, ikakhulukazi ukudlula ukuhamba okufutshane.
