Ama-optical fibers amashaneli anentambo adlulisa amasignali okubona. Sibhekisela kumasignali kagesi angadingekile esiteshini njengomsindo. Umsindo ohlelweni lokuxhumana ubekwe phezulu esignali, futhi kunomsindo ohlelweni lokuxhumana uma ingekho isignali yokudlulisela, i...

Ishaneli ixhuma idivayisi yokuxhumana yendawo yokuthumela kanye nesiphetho sokwamukela, futhi umsebenzi wayo ukudlulisa isignali ukusuka ekugcineni kokuthumela kuya ekugcineni kokwamukela. Ngokwemithombo yezokuxhumana ehlukene, iziteshi zingahlukaniswa zibe izigaba ezimbili: iziteshi ezingenantambo kanye ne-wire...

1. Ihlukaniswa ngensizakalo yezokuxhumana Ngokwezinhlobo ezahlukene zezinsiza zokuxhumana, izinhlelo zokuxhumana zingahlukaniswa zibe izinhlelo zokuxhumana ngocingo, izinhlelo zokuxhumana ngocingo, izinhlelo zokuxhumana ngedatha, izinhlelo zokuxhumana ngezithombe, njll. Ngoba umphakathi wocingo...

(1) Ukukhipha amakhodi komthombo kanye nokuqopha Imisebenzi emibili eyisisekelo: eyodwa iwukuthuthukisa ukusebenza kahle kokudluliswa kolwazi, okungukuthi, ngokusebenzisa uhlobo oluthile lobuchwepheshe bokubhala amakhodi ukuze uzame ukunciphisa inani lezimpawu ukuze kuncishiswe izinga lezimpawu. Okwesibili ukuqedela i-analog/digital (A/D) con...

Kokubili isignali nomsindo ekuxhumaneni kungathathwa njengezinqubo ezingahleliwe ezishintsha ngokuhamba kwesikhathi. Inqubo engahleliwe inezici zokuguquguquka okungahleliwe kanye nomsebenzi wesikhathi, ongachazwa ngemibono emibili ehlukene kodwa ehlobene eduze: (1) Inqubo engahleliwe i...

Imodi yokuxhumana isho imodi yokusebenza noma imodi yokudlulisa isignali phakathi kwezinhlangothi ezimbili zokuxhumana. 1. Ukuxhumana kwe-Simplex, i-half-duplex, kanye ne-full-duplex Ukuze kuxhunywe iphuzu-kuya-iphuzu, ngokuya ngesiqondiso nesikhathi sokudluliswa komlayezo, ...
