1. Ihlelwa ngokwenkonzo yonxibelelwano Ngokweentlobo ngeentlobo zeenkonzo zonxibelelwano, iinkqubo zonxibelelwano zinokwahlulwa zibe ziinkqubo zonxibelelwano ngetelegraph, iinkqubo zonxibelelwano ngomnxeba, iinkqubo zonxibelelwano lwedatha, iinkqubo zonxibelelwano ngemifanekiso, njl.

(1) Ukukhowudwa komthombo kunye nokuguqula iikhowudi Imisebenzi emibini esisiseko: enye kukuphucula ukusebenza kakuhle kokuhanjiswa kolwazi, oko kukuthi, ngokusebenzisa uhlobo oluthile lobugcisa bokufaka ikhowudi yokuzama ukunciphisa inani leesimboli ukunciphisa izinga lesimboli. Okwesibini kukugqiba i-analog/digital (A/D) con...

Zombini umqondiso kunye nengxolo kunxibelelwano zingathathwa njengeenkqubo ezizenzekelayo ezitshintshayo ngexesha. Inkqubo engaqhelekanga ineempawu zokuguquguquka okungahleliwe kunye nomsebenzi wexesha, onokuchazwa kwiimbono ezimbini ezahlukeneyo kodwa ezinxulumene ngokusondeleyo: (1) Inkqubo engaqhelekanga i...

Imo yonxibelelwano ibhekisa kwimowudi yokusebenza okanye imowudi yokuhanjiswa komqondiso phakathi kwamaqela amabini onxibelelwano. 1. I-Simplex, i-half-duplex, kunye ne-full-duplex yonxibelelwano Kunxibelelwano lwe-point-to-point, ngokwesikhokelo kunye nexesha lokuhanjiswa komyalezo, ...

Kwinkqubo yonxibelelwano lwedijithali, into efunyanwa ngummkeli sisimbuku somqondiso ogqithisiweyo kunye nengxolo yetshaneli. Ulwamkelo olululo lweempawu zedijithali lusekwe kubuncinci bempazamo enokwenzeka njengowona mgaqo "ogqwesileyo". Iimpazamo eziqwalaselwa kwesi sahluko zii...

Umzobo we-6-6 ngumzobo webhloko wenkqubo yokuhanjiswa kwesignali ye-digital baseband eqhelekileyo. Ubukhulu becala yenziwe ngesihluzo sokuthumela (ijenereyitha yomqondiso wetshaneli), itshaneli, ukufumana isihluzo kunye nesigqibo sesampulu. Ukuze kuqinisekiswe umsebenzi othembekileyo nocwangcisiweyo wenkqubo, i...
