Fonctiounen:
- Héich Stopband Ofleenung
- Kleng Gréisst
Et erlaabt Signaler mat Frequenzen méi grouss wéi e bestëmmte Schwell ze passéieren, awer refuséiert Signaler mat Frequenzen manner wéi dee Schwell. De passive Héichpassfilter ass e Filter deen aus passive Komponenten (R, L a C) besteet, mam Prinzip benotzt datt d'Reaktanz vu Kondensatoren an Induktoren mat der Frequenzännerung ännert. D'Virdeeler vum High-Pass-Filter sinn: de Circuit ass relativ einfach, brauch keng DC Stroumversuergung, héich Zouverlässegkeet; Et kann effektiv déi niddereg Frequenzsignal ënnerdrécken an d'Héichfrequenzsignal duerchgoen. Den Nodeel vum High-Passfilter ass datt d'Dämpfungsquote relativ grouss ass, wat d'Genauegkeet vum Signal beaflosse kann; D'Signal am Passband huet Energieverloscht, de Belaaschtungseffekt ass offensichtlech, an d'Benotzung vun Induktoren ass einfach elektromagnéitesch Induktioun ze verursaachen, an de Volume a Gewiicht vum Filter si relativ grouss wann d'Induktioun L grouss ass, wat net applicabel ass an déi niddereg Frequenz Domain.
1. Audioveraarbechtung: Héichpassfilter kënnen an der Audioveraarbechtung benotzt ginn fir Low-Frequenz Kaméidi oder aner onnéideg Low-Frequenz Signaler ze schwächen, doduerch d'Qualitéit vum Audio ze verbesseren.
2. Bildveraarbechtung: An der Bildveraarbechtung kënnen High-Pass-Filter benotzt ginn fir héichfrequenz Detailer an de Biller ze verbesseren, sou datt se méi kloer sinn.
3. Sensor Signal Veraarbechtung: Héich Pass Filtere kënne benotzt ginn fir niddereg Frequenz Kaméidi an Sensor Signaler ze filteren, doduerch d'Signal Zouverlässegkeet a Genauegkeet ze verbesseren.
4. Radiokommunikatioun: An der Radiokommunikatioun kënnen High-Pass-Filtere benotzt ginn fir Low-Frequenz Kaméidi an Interferenzsignaler ze filteren, doduerch d'Kommunikatiounsqualitéit ze verbesseren.
Qualwaveliwwert héich Stopband Oflehnung Héichpassfilter am Frequenzbereich bis zu 60GHz. D'Héichpassfilter gi wäit a ville Uwendungen benotzt.
