RF High Stopband Kukana Zosefera zazing'ono za Telecom High Pass

Imalola ma siginecha okhala ndi ma frequency akulu kuposa malire ena kuti adutse, koma imakana ma siginecha okhala ndi ma frequency ocheperako. Fyuluta yodutsa kwambiri ndi fyuluta yopangidwa ndi zinthu zopanda kanthu (R, L ndi C), pogwiritsa ntchito mfundo yakuti ma capacitor ndi ma inductors amasintha ndi kusintha kwafupipafupi. Ubwino wa fyuluta yapamwamba ndi: dera ndi losavuta, silifuna magetsi a DC, kudalirika kwakukulu; Imatha kupondereza bwino ma frequency otsika ndikupangitsa kuti ma frequency apamwamba adutse. Kuipa kwa fyuluta yapamwamba kwambiri ndikuti chiwerengero cha kuchepa ndi chachikulu, chomwe chingakhudze kulondola kwa chizindikiro; Chizindikiro cha passband chimakhala ndi mphamvu zowonongeka, mphamvu zolemetsa ndizodziwikiratu, ndipo kugwiritsa ntchito ma inductors ndikosavuta kuchititsa kulowetsedwa kwamagetsi, ndipo voliyumu ndi kulemera kwa fyuluta ndizokulirapo pamene inductance L ndi yaikulu, yomwe siigwiritsidwe ntchito otsika pafupipafupi ankalamulira.
