I-optical fiber iyishaneli enezintambo yokudlulisa amasignali okubona. Sibiza amasignali kagesi angafuneki esiteshini “umsindo Umsindo ohlelweni lokuxhumana ubekwe phezulu esignali. Uma ingekho isignali yokudlulisela, kunomsindo futhi ohlelweni lokuxhumana. &#...

Ishaneli iyisisetshenziswa sokuxhumana esixhuma isiphetho sokudlulisela kanye nesiphetho sokwamukela, futhi umsebenzi waso ukudlulisa amasignali ukusuka ekugcineni kokudlulisela kuya ekugcineni kokwamukela. Ngokusho kwemidiya ehlukene yokudlulisa, iziteshi zingahlukaniswa ngezigaba ezimbili: iziteshi ezingenantambo kanye nezintambo ...

Kulesi sihloko ngizokhuluma nge-Communication System Model ngemininingwane ihlanganisa izingxenye zayo ezi-5, (1) Ukubhala amakhodi komthombo kanye nokukhishwa kwamakhodi, (2) Ukubhala ngekhodi nokukhishwa kwamakhodi kwamashaneli, (3) Ukubethela nokukhipha ukubethela, (4) Ukushintshwa kwedijithali kanye ukwehlisa, (5) Ukuvumelanisa. Masingene sijule...

1. Ukuhlelwa kwebhizinisi lezokuxhumana Ngokwezinhlobo ezahlukene zezinsiza zokuxhumana, izinhlelo zokuxhumana zingahlukaniswa zibe izinhlelo zokuxhumana ngocingo, izinhlelo zokuxhumana ngocingo, izinhlelo zokuxhumana ngedatha, kanye nezinhlelo zokuxhumana ngezithombe. Ngoba ukuxhumana kwefoni ...

Kokubili isignali nomsindo ekuxhumaneni kungathathwa njengezinqubo ezingahleliwe ezihluka ngokuhamba kwesikhathi. Inqubo engahleliwe inezici zokuguquguquka okungahleliwe kanye nomsebenzi wesikhathi, futhi ingachazwa ngemibono emibili ehlukene kodwa ehlobene eduze: ① inqubo engahleliwe iqoqo le...

Indlela yokuxhumana yindlela abantu ababili abakhuluma bodwa abasebenzisana ngayo noma ukuthumela imiyalezo. 1. Ukuxhumana kwe-Simplex, i-half-duplex kanye ne-full-duplex Ukuze uthole ukuxhumana kwephuzu kuya kwephuzu, ngokusho kwesiqondiso kanye nobudlelwane besikhathi sokudluliswa komlayezo, imodi yokuxhumana c...
