Mawonekedwe:
- Kukana Kwambiri kwa Stopband
- Kukula Kwakung'ono
Chosefera chotsika ndi chosefera chomwe chimasunga ma siginecha otsika pochotsa ma siginecha apamwamba kwambiri. Imalola ma siginecha okhala ndi ma frequency ocheperako kuti adutse, koma imakana ma siginecha okhala ndi ma frequency akulu kuposa malirewo.
1. Zizindikiro zokha zomwe zili pansi pa mafupipafupi zimaloledwa kudutsa, pamene zizindikiro pamwamba pake zimasefedwa kapena kufooka.
2. Podutsa mazizindikiro otsika, palibe pafupifupi kusintha kwa gawo.
3. Kawirikawiri, capacitor imodzi kapena angapo ndi inductors amagwiritsidwa ntchito popanga zosefera zochepa.
1.chizindikiro chosalala
fyuluta yotsika kwambiri imagwiritsidwa ntchito makamaka kusalaza chizindikiro, imatha kuchotsa phokoso mu siginecha yapamwamba kwambiri, kuti chizindikirocho chikhale chokhazikika. Pamene chizindikiro chosalala chikufunika, fyuluta yotsika kwambiri imatha kuchotsa phokoso lachisokonezo chapamwamba, motero zimapangitsa kuti dongosolo likhale lodalirika komanso lokhazikika.
2.kuchepetsa phokoso
fyuluta yotsika kwambiri sidzakhudza chizindikiro chotsika, pamene kusunga chizindikiro chotsika, phokoso lapamwamba likhoza kusefedwa. Pokonza ma audio kapena kujambula zithunzi, zosefera zotsika zimatha kusefa phokoso ndikupangitsa kuti chizindikirocho chimveke bwino.
3.chepetsani cholakwika
Sefa yotsika pang'ono imatha kuchepetsa cholakwikacho, makamaka yoyenera kuyeza kolondola kwa zida. Mu miyeso ina yovuta, fyuluta yotsika imatha kuchotsa phokoso, kusokoneza ndi zinthu zina, kuti zotsatira zake zikhale zolondola komanso zodalirika.
4.wide osiyanasiyana ntchito
Zosefera zotsika zimakhala ndi mapulogalamu osiyanasiyana, kuchokera pamawu mpaka pazithunzi, kuchokera pakulankhulana mpaka kuwongolera, pafupifupi kulikonse. Mwachitsanzo, pokonza ma sign a baseband, fyuluta yotsika ndiyofunikira.
Polankhulana, zosefera zotsika zimatha kusefa phokoso lambiri, kusokoneza, ndi zina zambiri, kuti zitsimikizire kulumikizana; M'munda wowongolera, fyuluta yotsika-pass ingagwiritsidwe ntchito powongolera ma siginecha ndi kusefa kwaphokoso.
Qualwaveimapereka zosefera zotsika kwambiri zokana zoyimitsa pama frequency osiyanasiyana a DC-50GHz. Zosefera zotsika zotsika zimagwiritsidwa ntchito kwambiri pazinthu zambiri.
