Imiklela inductor

Ukumelana ne-DC AC yindlela elula yokuthetha, iyakwazi ukwahlula kwaye inciphise isignali ye-AC, okanye yenze isekethe ye-resonant kunye ne-resistor kunye ne-capacitor, ilungelelanise ulwimi kwaye ukhethe ukuphindaphinda. I-coil ye-inductance kunye ne-capacitor ngokuhambelanayo inokwenza i-LC tuning circuit. Oko kukuthi, ukuba i-oscillation yendalo i-0 yesekethe ilingana nokuphindaphinda kwe-non-AC signal, i-inductive reactance kunye ne-capacitive reactance yesekethe nazo ziyalingana, ngoko ke amandla ombane ajikeleza emva naphambili phakathi kwe-inductor kunye ne-capacitor. , eyona nto i-resonance phenomenon yesekethe ye-LC. Xa i-resonant, i-inductive reactance kunye ne-capacitive reactance yesekethe iyalingana kwaye ibuyele umva, ngoko ke i-inductive reactance ye-resonant yangoku yesekethe incinci, kunye nexabiso langoku (libhekisa ku-0 AC signal), ngoko ke i-LC resonant circuit ine. umsebenzi wokukhetha i-frequency, kwaye unokukhetha isignali ye-AC yefrikhwensi ethile.

Ukuphakama komthamo wesignali, kokukhona kulula ukuhanjiswa. Nangona kunjalo, imigca yemiqondiso ngokubanzi ayinamaleko okukhusela. Le migca yemiqondiso iba zii-eriyali ezilungileyo kakhulu zokufumana zonke iintlobo zemiqondiso emdaka ejikelezayo kwindawo engqongileyo. Ukuba le miqondiso ibekwe ngaphezulu kweempawu zokuqala ezigqithiselweyo, ziya kutshintsha imiqondiso yantlandlolo eluncedo kwaye iphazamise kakhulu ukusebenza okuqhelekileyo kwezixhobo zombane, Ke ngoko, kuyafuneka ukunciphisa ukuphazamiseka kwe-electromagnetic (EM) yezixhobo zombane. Ngaphantsi kwesenzo sendandatho yamagnetic, nokuba isignali eqhelekileyo kunye neyoncedo idlula kakuhle, inokucinezela isignali yokuphazamiseka kwe-high-frequency kakuhle, kwaye ixabiso liphantsi. I-coil ye-magnetic inductance coil ikwadlala indima ebalulekileyo kwingxolo engaphezulu, isignali yokuhlola, ukuzinzisa ngoku kunye nokucinezela ukuphazamiseka kwamaza ombane.
