Vipengele:
- Kukataliwa kwa Bendi ya Juu
- Ukubwa Mdogo
Huruhusu mawimbi yenye masafa makubwa zaidi ya kizingiti fulani kupita, lakini hukataa mawimbi yenye masafa ya chini ya kizingiti hicho. Kichujio cha kupita kwa kiwango cha juu ni kichungi kinachojumuisha vipengee vya kupita (R, L na C), kwa kutumia kanuni kwamba mwitikio wa capacitors na inductors hubadilika na mabadiliko ya frequency. Faida za chujio cha juu-kupita ni: mzunguko ni rahisi, hauhitaji usambazaji wa umeme wa DC, kuegemea juu; Inaweza kukandamiza kwa ufanisi mawimbi ya masafa ya chini na kufanya mawimbi ya masafa ya juu kupita. Hasara ya chujio cha juu-kupita ni kwamba kiwango cha attenuation ni kikubwa, ambacho kinaweza kuathiri usahihi wa ishara; Ishara katika bendi ya kupitisha ina hasara ya nishati, athari ya mzigo ni dhahiri, na matumizi ya inductors ni rahisi kusababisha introduktionsutbildning sumakuumeme, na kiasi na uzito wa chujio ni kiasi kikubwa wakati inductance L ni kubwa, ambayo si husika katika. kikoa cha masafa ya chini.
1. Uchakataji wa sauti: Vichujio vya pasi za juu vinaweza kutumika katika usindikaji wa sauti ili kudhoofisha kelele ya masafa ya chini au mawimbi mengine yasiyo ya lazima ya masafa ya chini, na hivyo kuboresha ubora wa sauti.
2. Uchakataji wa picha: Katika uchakataji wa picha, vichujio vya kupita kiwango cha juu vinaweza kutumika kuboresha maelezo ya masafa ya juu katika picha, na kuzifanya kuwa wazi zaidi.
3. Uchakataji wa mawimbi ya vitambuzi: Vichujio vya kupita kiwango cha juu vinaweza kutumika kuchuja kelele ya masafa ya chini katika mawimbi ya vitambuzi, na hivyo kuboresha kutegemewa na usahihi wa mawimbi.
4. Mawasiliano ya redio: Katika mawasiliano ya redio, vichungi vya kupita kiwango cha juu vinaweza kutumika kuchuja mawimbi ya sauti ya chini-frequency na ishara za kuingiliwa, na hivyo kuboresha ubora wa mawasiliano.
Qualwavehutoa vichujio vya juu vya kukataza vichujio vya kupita katika masafa ya hadi 60GHz. Vichungi vya kupitisha juu hutumiwa sana katika programu nyingi.
