Imtixaanka Shaybaarka Tijaabada BTF (RF) Horudhac Sawir leh

Tijaabada Shaybaarka Tijaabada BTF (RF).

sharaxaad gaaban:

Soo noqnoqda raadiyaha waxaa loo yaqaan RF, soo noqnoqda raadiyaha waa RF hadda, waa nooc ka mid ah hirarka koronto ee AC beddelka hirarka korantada ee gaaban. Shaybaarka Tijaabada BTF waxa uu leeyahay shaybaadhka soo noqnoqda raadiyaha oo dhamaystiran. Hadafka beddelka ah ee isbeddelaya wax ka yar 1000 jeer ilbiriqsikiiba waxa loo yaqaannaa hadda jira oo hooseeya, iyo soo noqnoqda oo ka badan 10,000 jeer waxa loo yaqaannaa hadda sare-frequency, inta jeer ee raadiyahana waa hadda-frequency sare. Nadaamka telefishinka ee cable-ku waxa uu isticmaalayaa habka gudbinta inta jeer ee raadiyaha.

Qalabka elektaroonigga ah, korantada ayaa ku dhex qulqulaysa kirishbooyada waxaana ku wareegsan goob magnet ah. Kala beddelka hadda waxa uu dhex maraa kirishbooyada, waxaana beddesha goob elektromagnetic ah oo ku wareegsan kirishbooyada, oo loo yaqaan hirarka korantada.

Sharaxaad Gaaban

Marka inta jeer ee hirarka korantada ee korantada uu ka hooseeyo 100kHz, mowjadda elektromagnetic-ga waxaa nuugi doona oogada oo ma sameyn karaan gudbin wax ku ool ah, laakiin marka inta jeer ee hirarka korantada uu ka sarreeyo 100kHz, hirarka korantada wuxuu ku faafi karaa hawada waxaana ka muuqanaya ionosphere oo ku yaal cidhifka dibadda ee jawiga, samaynta awoodda gudbinta fogaanta fog, waxaan ugu yeernaa hirarka korantada ee soo noqnoqda ee leh raadiyaha awoodda gudbinta fog inta jeer, Ingiriisiga soo gaabinta: RF
