Intshayelelo yeBTF yoVavanyo lweLebhu yeRadiyo (RF) Umfanekiso obonakalayo

Intshayelelo yeBTF yoVavanyo lweLebhu yeRadio frequency (RF).

inkcazelo emfutshane:

Ifrikhwensi kanomathotholo ibizwa ngokuba yiRF, amaza onomathotholo yiRF yangoku, luhlobo lwe-AC yokutshintsha i-electromagnetic wave ngokufutshane. ILebhu yoVavanyo lwe-BTF inelebhu epheleleyo yerediyo. Ukutshintsha kwangoku okutshintsha amaxesha angaphantsi kwe-1000 ngesekondi kubizwa ngokuba yi-low-frequency current, kwaye i-frequency current engaphezulu kwamaxesha angama-10,000 ibizwa ngokuba yi-high-frequency current, kwaye i-rediyo frequency yi-high-frequency current. Inkqubo kamabonakude wentambo isebenzisa imowudi yosasazo yerediyo.

Kwi-elektroniki, umsinga wombane uhamba nge-conductor kunye ne-magnetic field form around it. Ukutshintshana kwangoku kudlula kwi-conductor, kwaye indawo ye-electromagnetic field yenziwa ijikeleze i-conductor, ebizwa ngokuba yi-electromagnetic wave.

Ingcaciso emfutshane

Xa i-electromagnetic wave frequency ingaphantsi kwe-100kHz, i-electromagnetic wave iya kutsalwa ngaphezulu kwaye ayinakwenza ukuhanjiswa okusebenzayo, kodwa xa i-electromagnetic wave frequency ingaphezulu kwe-100kHz, i-electromagnetic wave inokusasazeka emoyeni kwaye ibonakaliswe I-ionosphere kumda ongaphandle we-atmosfera, isenza isakhono sothumelo lomgama omde, sibiza i-high-frequency electromagnetic wave kunye nesakhono sosasazo lomgama omde, isifinyezo sesiNgesi: RF
