Intshayelelo yeSakhiwo esiSiseko
Umqhubi wangaphakathi
Umqhubi wangaphakathi yinxalenye ephambili yeentambo ze-coaxial zaselwandle, ngokuyintloko enoxanduva lokudlulisa imiqondiso. Ukusebenza kwayo kuchaphazela ngokuthe ngqo ukusebenza kakuhle kunye nomgangatho wokudluliselwa kwemiqondiso. Kwiinkqubo zonxibelelwano lweenqanawa, umqhubi wangaphakathi unomsebenzi wokudlulisa imiqondiso ukusuka kwizixhobo zokudlulisa ukuya kwizixhobo zokwamkela, nto leyo eyenza ukuzinza nokuthembeka kwayo kubaluleke kakhulu.
Umqhubi wangaphakathi udla ngokwenziwa ngobhedu olucocekileyo kakhulu. Ubhedu luneempawu ezintle kakhulu zokuqhuba, nto leyo eqinisekisa ukulahleka okuncinci kwesignali ngexesha lokudluliselwa. Ukongeza, ubhedu luneempawu ezintle zoomatshini, nto leyo evumela ukuba lukwazi ukumelana noxinzelelo oluthile loomatshini. Kwezinye izicelo ezikhethekileyo, umqhubi wangaphakathi unokuba yithusi elifakwe isilivere ukuphucula ukusebenza kokuqhuba. Ubhedu olufakwe isilivere ludibanisa iimpawu zokuqhuba zobhedu kunye neempawu zesilivere ezinganyangekiyo kakhulu, nto leyo enika ukusebenza okugqwesileyo ekudlulisweni kwesignali efumaneka rhoqo.
