Xa umthamo wokuhanjiswa kwejelo lomzimba liphezulu kunemfuno yomqondiso omnye, umjelo unokwabelwana ngeempawu ezininzi, umzekelo, umgca we-trunk wenkqubo yefowuni uhlala unamawaka emiqondiso ethunyelwa kwifiber enye. I-Multiplexing yitekhnoloji yokusombulula indlela ...

(1) AMI ikhowudi AMI(Olunye uphawu Inversion) ikhowudi ligama elipheleleyo lelinye uphawu inversion ikhowudi, umthetho wayo wokhowudo kukuguqula ngokutshintsha ikhowudi yomyalezo "1" (maki) ukuya "+1" kunye "-1", ngelixa i "0" (uphawu olungenanto) luhlala lungatshintshanga. Umzekelo...

Xa sihambisa umqondiso, nokuba ngumqondiso we-optical okanye umbane wombane okanye i-wireless signal, ukuba ihanjiswe ngokuthe ngqo, isibonakaliso sithinteka ekuphazamisekeni kwengxolo, kwaye kunzima ukufumana ulwazi oluchanekileyo ekupheleni kokufumana. Ukuze t...

Iindlela ezisisiseko zokumodareyitha kwedijithali kokubini zezi: isitshixo se-amplitude yokubini (2ASK)- utshintsho lweamplitude yesiginali yomphathi; I-binary frequency shift keying (2FSK)- utshintsho oluqhelekileyo lwesignali yomthwali; Isigaba sesibini sokutshintsha isitshixo (2PSK)- Utshintsho lwesigaba somthwali si...

I-WiFi ngumgangatho wothungelwano lwengingqi olungenangcingo lwamazwe ngamazwe (WLAN), igama elipheleleyo elithi Wireless Fidelity, ekwaziwa ngokuba yi-IEEE802.11b standard. I-WiFi yayisekelwe kwiprotocol ye-IEEE802.11, eyapapashwa ngo-1997, ichaza umaleko we-WLAN we-MAC kunye nemigangatho yomgangatho womzimba. Ukulandela i...

I-Optical iso image debugging Ithagethi: Umlinganiselo wokuphela koPhando kunye nesigaba sophuhliso: phakathi kwe-10-15 (enkulu ingcono kunencinci), ngokwemeko yangempela inokufaneleka ukuphucula umlinganiselo wokuphela, kodwa ungekho phantsi kakhulu. Inxulumene novakalelo. Quiver...
