I-inductor yokushisa

I-DC resistance AC iyindlela elula yokusho, ingakwazi ukuhlukanisa futhi yehlise isignali ye-AC, noma yakhe isekethe ezwakalayo ene-resistor ne-capacitor, ilungise ulimi bese ikhetha imvamisa. Ikhoyili ye-inductance kanye ne-capacitor ngokuhambisana ingakha i-LC tuning circuit. Okusho ukuthi, uma imvamisa ye-oscillation yemvelo engu-0 yesekethe ilingana nemvamisa yesiginali engeyona i-AC, ukusabela kwe-inductive kanye nokusabela kwe-capacitive kwesekethe nakho kuyalingana, ngakho-ke amandla kazibuthe azungeza emuva naphambili phakathi kwe-inductor ne-capacitor. , okuyi-resonance phenomenon yesekethe ye-LC. Uma i-resonant, ukusabela kwe-inductive kanye nokusabela kwe-capacitive kwesekethe kuyalingana futhi kuyahlehla, ngakho-ke ukusabela kwe-inductive kwengqikithi yamanje yesekethe kuncane, kanye nenani lamanje (libhekisa ku- - 0 AC isignali), ngakho-ke isekethe ye-resonant ye-LC ine umsebenzi wokukhetha imvamisa, futhi ingakhetha isignali ye-AC yefrikhwensi ethile.

Uma imvamisa yesignali iphezulu, kuba lula ukuyidlulisela. Nokho, imigqa yesignali evamile ayinakho isendlalelo esivikelayo. Le migqa yamasignali iba ama-antenna amahle kakhulu ukuthola zonke izinhlobo zezimpawu ezingcolile zemvamisa ephezulu endaweni ezungezile. Uma lezi zimpawu zibekwe phezulu kumasiginali adlulisiwe okuqala, azoshintsha amasiginali awusizo adlulisiwe futhi aphazamise kakhulu ukusebenza okuvamile kwemishini kagesi, Ngakho-ke, kuyadingeka ukunciphisa ukuphazanyiswa kwe-electromagnetic (EM) kwemishini kagesi. Ngaphansi kwesenzo sendandatho kazibuthe, ngisho noma isignali evamile newusizo idlula kahle, ingacindezela isignali yokuphazamiseka kwemvamisa ephezulu kahle kakhulu, futhi izindleko ziphansi. Ikhoyili ye-magnetic rod inductance nayo idlala indima ebalulekile phezu komsindo, isignali yokuhlola, ukusimama kwamanje kanye nokucindezela ukuphazamiseka kwamagagasi kagesi.
