Mawonekedwe:
- Kukana Kwambiri kwa Stopband
- Kukula Kwakung'ono
Band Reject Selter ndi fyuluta yomwe imagwiritsidwa ntchito pokonza ma siginecha kutsitsa kukula kwa siginecha mkati mwa mayendedwe apadera pomwe imalola kuti ma siginecha amitundu ina adutse. Mfundo yogwirira ntchito ya gulu lokana fyuluta ndikusanthula chizindikiro cholowera mumayendedwe pafupipafupi, ndikusankha kupondereza matalikidwe a siginecha molingana ndi ma frequency omwe adanenedwa, kuti mukwaniritse kuchepetsa phokoso pamafupipafupi omwe atchulidwa.
Kutumiza kwa 1.Block chizindikiro mumtundu wina wafupipafupi: fyuluta yoyimitsa band ilibe ntchito yosinthira ya zero, koma imakhala ndi ntchito yochepetsera yochepa pafupipafupifupi yapakati. Chifukwa chake, imatha kuletsa kufalikira kwa mazizindikiro kudzera mumtundu wake wapakati pafupipafupi.
2.Lolani zizindikiro zina zafupipafupi kuti zidutse: Kuwonjezera pa ma frequency apakati, fyuluta ya band-stop imalola kuti zizindikiro za ma frequency ena onse adutse. Izi zimalola zosefera za band-stop kuti zigwiritsidwe ntchito kuchotsa phokoso, kusokoneza ndikukwaniritsa zofunikira pakuyankha pafupipafupi.
3.Kusokoneza mafunde ang'onoang'ono: poyerekeza ndi mitundu ina ya zosefera, zosefera za band-stop zimakhala ndi zosokoneza zazing'ono. Izi zikutanthauza kuti ikhoza kusunga bwino mawonekedwe ndi matalikidwe a chizindikiro chomwe chikudutsa pa fyuluta.
4.Broadband signal processing: Fyuluta yoyimitsa bandi ingagwiritsidwe ntchito pokonza zizindikiro za burodibandi, chifukwa imatha kusunga zigawo zambiri zafupipafupi ndikungoletsa maulendo apadera.
5. Yankho la gawo: Kuyankha kwa gawo la fyuluta yoyimitsa bandi kumadalira kapangidwe kake ndi kukhazikitsidwa kwake, koma kawirikawiri kumakhala pakati pa fyuluta yotsika kwambiri ndi fyuluta yapamwamba.
1. Kukonza ma siginecha amagetsi: Zosefera zoyimitsa bandi zitha kugwiritsidwa ntchito kusefa ma frequency ena osokoneza pokonza ma siginecha amagetsi, potero kumapangitsa kuti ma sigino akhale abwino.
2. Kulankhulana pawailesi: Polankhulana pawailesi, zosefera zoyimitsa bandi zitha kugwiritsidwa ntchito kusefa ma frequency osafunika pa ma siginoloji, potero kumapangitsa kuti kulumikizana kukhale koyenera.
3. Magetsi amagetsi apamwamba: Zosefera zoyimitsa band zitha kugwiritsidwa ntchito kusintha kuyankha pafupipafupi m'mabwalo kuti mukwaniritse magwiridwe antchito ofunikira.
4. Zida zamankhwala: Zosefera zoyimitsa band zitha kugwiritsidwa ntchito pazida zamankhwala, monga zida za electrocardiogram, kusefa ma frequency a minofu ndi zina zosokoneza zakunja.
Qualwaveimapereka zosefera zapamwamba zokanira zokanira pama frequency a DC-18GHz. Zosefera zokana gulu zimagwiritsidwa ntchito kwambiri pazinthu zambiri.
