Karatteristiċi:
- Ċaħda Għolja Stopband
- Daqs Żgħir
Filtru low pass huwa filtru tal-ipproċessar tas-sinjali li jippreserva sinjali ta 'frekwenza baxxa billi jneħħi sinjali ta' frekwenza għolja. Jippermetti li jgħaddu sinjali bi frekwenzi inqas minn ċertu limitu, iżda jirrifjuta sinjali bi frekwenzi akbar minn dak il-limitu.
1. Sinjali biss taħt frekwenza speċifika jitħallew jgħaddu, filwaqt li sinjali 'l fuq minn dik il-frekwenza huma ffiltrati jew imdgħajfa.
2. Meta tgħaddi minn sinjali ta 'frekwenza baxxa, kważi m'hemm l-ebda bidla fil-fażi.
3. Normalment, wieħed jew aktar capacitors u indutturi jintużaw biex jinbnew filtri low-pass.
sinjal 1.smooth
filtru low-pass huwa prinċipalment użat biex twitti s-sinjal, jista 'jneħħi l-istorbju fis-sinjal ta' frekwenza għolja, sabiex is-sinjal isir aktar stabbli. F'każijiet fejn ikun meħtieġ sinjal bla xkiel, il-filtru low-pass jista 'jneħħi l-istorbju ta' interferenza ta 'frekwenza għolja, u b'hekk is-sistema tkun aktar affidabbli u stabbli.
tnaqqis 2.noise
filtru low-pass mhux se jaffettwa s-sinjal ta 'frekwenza baxxa, filwaqt li jżomm is-sinjal ta' frekwenza baxxa, il-ħoss ta 'frekwenza għolja jista' jiġi ffiltrat. Fl-ipproċessar tal-awdjo jew fl-ipproċessar tal-immaġni, il-filtri low-pass jistgħu jiffiltraw l-istorbju u jagħmlu s-sinjal ipproċessat aktar ċar.
3.reduce l-iżball
filtru low-pass jista 'jnaqqas l-iżball, speċjalment adattat għall-kejl ta' strument ta 'preċiżjoni. F'xi kejl impenjattiv, il-filtru low-pass jista 'jneħħi l-istorbju, l-interferenza u fatturi oħra, sabiex ir-riżultati tal-kejl ikunu aktar preċiżi u affidabbli.
4.wide firxa ta 'applikazzjoni
Il-filtru low pass għandu firxa wiesgħa ħafna ta 'applikazzjonijiet, minn awdjo għal immaġni, mill-komunikazzjoni għall-kontroll, kważi kullimkien. Pereżempju, fl-ipproċessar tas-sinjal tal-banda bażi, huwa meħtieġ filtru low-pass.
Fil-komunikazzjoni, filtru low-pass jista 'jiffiltra l-istorbju ta' frekwenza għolja, interferenza, eċċ., Biex tiġi żgurata l-kwalità tal-komunikazzjoni; Fil-qasam tal-kontroll, il-filtru low-pass jista 'jintuża għall-illixxar tas-sinjali u l-iffiltrar tal-istorbju.
Qualwavejipprovdi filtri ta 'pass baxx ta' rifjut ta 'stopband għoli f'medda ta' frekwenza DC-50GHz. Il-filtri low pass jintużaw ħafna f'ħafna applikazzjonijiet.
