Abasebenzisi abaninzi kwaye abaninzi sele beqalile ukusebenzisa uphawu lwedijithaliumnxeba. Abasebenzisi abaninzi baxhaphaza imiqondiso ye-analog enemiqondiso yedijithali. Yintoni ifowuni ye-analog? Yintoni ifowuni yomqondiso wedijithali?
Ifowuni ye-analog-ifowuni edlulisela isandi ngemiqondiso ye-analog. Isiginali ye-ANAG yoMbane ikakhulu ibhekisele kwi-Ameslitux kwaye ihambelana nomqondiso ohambelana nombane, lo mqondiso unokuba sisiphaluka se-analog kwimisebenzi eyahlukeneyo, ukunyuka, ukongeza, njalo njalo. Iimpawu ze-analog zikhona naphi na kwindalo, ezinje ngotshintsho lobushushu lwemihla ngemihla.
Umqondiso wedijithali luhlobo lwedijithali womqondiso wexesha (omelwe kukulandelelana kwe-1 ne-0), ihlala ifumaneka kumqondiso we-analog.
Izibonelelo kunye nokungalungisi kwemiqondiso yedijithali:
I-1, ithatha ibhendi ejikelezayo ebanzi. Kuba umgca uhambisa uphawu lwepulse, usulelo lwedijithaliUlwazi lwelizwiKufuneka i-akhawunti ye-20k-64kz I-Bandwidth, kunye ne-Tolog Vitch kuphela ye-4khz bandwidth, oko kukuthi, iiakhawunti zomqondiso we-PCM ze-Analog Vit. Kwisitishi esithile, ireyithi yayo yokusetyenziswa incitshisiwe, okanye iimfuno zayo zomgca ziyanda.
2, Iimfuneko zobugcisa zintsonkothile, ngakumbi itekhnoloji yolungelelwaniso ifuna ukuba sichanekile. Ukuqonda ngokuchanekileyo intsingiselo yomthumeli, umamkeli kufuneka akwazi ukwahlula-hlula ikhowudi nganye, kwaye afumane isiqalo seqela ngalinye lolwazi, elifuna ukuba umthumeli kunye nokufumana inethiwekhi yedijithali, ingxaki yokulungelelanisa iya kuba nzima ngakumbi ukusombulula.
I-3, i-analog / uguqulo lwedijithali luya kuzisa impazamo yexabiso. Ngokusetyenziswa kweesekethe ezihlanganisiweyo ezinkulu kunye nokuthandwa kwemithombo yosulelo yebhendi efana nefibre, imiqondiso yedijithali isetyenziselwa ukuguqulwa kwe-analog / imiqondiso ye-analog, kunye neempazamo zedijithali, kunye ne-digital, kunye ne-digital.
