Karatteristiċi:
- Ċaħda Għolja Stopband
- Daqs Żgħir
Jippermetti li jgħaddu sinjali bi frekwenzi akbar minn ċertu limitu, iżda jirrifjuta sinjali bi frekwenzi inqas minn dak il-limitu. Il-filtru passiv high-pass huwa filtru magħmul minn komponenti passivi (R, L u C), bl-użu tal-prinċipju li r-reattanza ta 'capacitors u indutturi tinbidel bil-bidla tal-frekwenza. Il-vantaġġi tal-filtru high-pass huma: iċ-ċirkwit huwa relattivament sempliċi, ma jeħtieġx provvista ta 'enerġija DC, affidabilità għolja; Jista 'jrażżan b'mod effettiv is-sinjal ta' frekwenza baxxa u jagħmel is-sinjal ta 'frekwenza għolja jgħaddi. L-iżvantaġġ tal-filtru high-pass huwa li r-rata ta 'attenwazzjoni hija relattivament kbira, li tista' taffettwa l-eżattezza tas-sinjal; Is-sinjal fil-passband għandu telf ta 'enerġija, l-effett tat-tagħbija huwa ovvju, u l-użu ta' indutturi huwa faċli biex jikkawża induzzjoni elettromanjetika, u l-volum u l-piż tal-filtru huma relattivament kbar meta l-inductance L hija kbira, li mhix applikabbli f' il-qasam tal-frekwenza baxxa.
1. Ipproċessar tal-awdjo: Filtri ta 'passaġġ għoli jistgħu jintużaw fl-ipproċessar tal-awdjo biex idgħajjef il-ħoss ta' frekwenza baxxa jew sinjali oħra ta 'frekwenza baxxa mhux meħtieġa, u b'hekk titjieb il-kwalità tal-awdjo.
2. Ipproċessar ta 'l-immaġini: Fl-ipproċessar ta' l-immaġini, filtri ta 'pass għoli jistgħu jintużaw biex itejbu d-dettalji ta' frekwenza għolja fl-immaġini, u jagħmluhom aktar ċari.
3. Ipproċessar tas-sinjal tas-sensorju: Filtri ta 'passaġġ għoli jistgħu jintużaw biex jiffiltraw il-ħoss ta' frekwenza baxxa fis-sinjali tas-sensuri, u b'hekk itejbu l-affidabbiltà u l-eżattezza tas-sinjal.
4. Komunikazzjoni bir-radju: Fil-komunikazzjoni bir-radju, filtri high pass jistgħu jintużaw biex jiffiltraw ħsejjes ta 'frekwenza baxxa u sinjali ta' interferenza, u b'hekk itejbu l-kwalità tal-komunikazzjoni.
Qualwavejipprovdi filtri ta 'pass għoli ta' rifjut ta 'stopband għoli f'firxa ta' frekwenza sa 60GHz. Il-filtri high pass jintużaw ħafna f'ħafna applikazzjonijiet.
