(1) fyuluta yotsika
Kuchokera pa 0 mpaka F2, mawonekedwe a amplitude-frequency ndi athyathyathya, omwe amatha kupangitsa kuti magawo omwe ali pansi pa F2 adutse mosavutikira, pomwe apamwamba kuposa F2 amachepetsedwa kwambiri.
(2) fyuluta yapamwamba
Mosiyana ndi kusefa kwapansi, mawonekedwe ake amplitude-frequency amakhala athyathyathya kuchokera pafupipafupi F1 mpaka infinity.Zimalola kuti zigawo zafupipafupi za siginecha pamwamba pa F1 zidutse mosavutikira, pomwe zomwe zili pansi pa F1 zidzachepetsedwa kwambiri.
(3) gulu pass fyuluta
Chiphaso chake chili pakati pa F1 ndi F2.Zimalola kuti zigawo zafupipafupi za sigino zikhale zapamwamba kuposa F1 komanso zotsika kuposa F2 kuti zidutse mosavutikira, pomwe zida zina zimachepetsedwa.
(4) gulu loyimitsa fyuluta
Mosiyana ndi kusefa kwa bandpass, gulu loyimitsa lili pakati pa F1 ndi F2.Imachepetsera ma frequency a siginecha apamwamba kuposa F1 komanso otsika kuposa F2, ndipo magawo ena onse amadutsa pafupifupi mosayembekezereka.
Electromagnetic interference (EMI) fyuluta yamagetsi ndi chipangizo chosagwira ntchito chopangidwa ndi inductance ndi capacitance.Imakhala ngati zosefera ziwiri zotsika, imodzi imalepheretsa kusokoneza wamba ndipo inayo imachepetsa kusokoneza kwamitundu yosiyanasiyana.Imachepetsera mphamvu ya rf mu bandi yoyimitsa (nthawi zambiri imakhala yopitilira 10KHz) ndikulola kuti ma frequency amphamvu adutse ndikutsitsa pang'ono kapena osatsitsa.Zosefera zamagetsi za EMI ndiye chisankho choyamba kwa mainjiniya opanga zamagetsi kuti aziwongolera ndikuwongolera EMI.
(A) Pogwiritsa ntchito mawonekedwe a capacitor omwe amadutsa ma frequency apamwamba komanso kudzipatula kwafupipafupi, kusokoneza pafupipafupi kwa waya wamoyo ndi waya wosalowererapo kumalowetsedwa mu waya wapansi (njira wamba), kapena kusokoneza kwanthawi yayitali kwa waya wamoyo kumayambitsidwa. mu waya wosalowerera (njira yosiyana);
(B) Onetsani kusokoneza kwapafupipafupi komwe kumabwereranso ku gwero losokoneza pogwiritsa ntchito mawonekedwe a impedance ya coil inductor;
Kuti muchepetse kukana kwapansi, fyulutayo iyenera kuyikidwa pazitsulo zoyendetsera zitsulo kapena kulumikizidwa ndi malo ozungulira pafupi ndi malo otchinga pansi kuti mupewe kutsekeka kwakukulu komwe kumachitika chifukwa cha mawaya ocheperako.
Zolozera zingapo ziyenera kuganiziridwa posankha fyuluta ya mzere wamagetsi.Yoyamba idavotera ma voliyumu / ovotera pakali pano, kutsatiridwa ndi kutayika kwa kuyika, kutayikira kwapano (dc mphamvu fyuluta samaganizira kukula kwa kutayikira kwapano), kukula kwake, ndipo pamapeto pake ndiye kuyesa kwamagetsi.Popeza kuti mkati mwa fyuluta nthawi zambiri kumakhala poto, mawonekedwe a chilengedwe sizovuta kwambiri.Komabe, mawonekedwe a kutentha kwa zinthu zophika ndi fyuluta capacitor amakhala ndi chikoka pazachilengedwe za fyuluta yamagetsi.
Kuchuluka kwa fyuluta kumatsimikiziridwa makamaka ndi inductance mu dera la fyuluta.Kuchuluka kwa voliyumu ya inductance coil, kumapangitsanso kuchuluka kwa fyuluta.
