Lim tsis lees txais Band
| Tus thawj coj-mw | Kev Taw Qhia rau cov lim dej tsis lees txais band |
Cheng du leader microwave Tech.,(leader-mw) Band Reject Filter (tseem hu ua bandstop filter lossis BSF), ib qho khoom tshwj xeeb uas ua lub luag haujlwm tseem ceeb hauv kev tswj cov zaus ntawm lub teeb liab. Tsis zoo li cov lim band-pass, uas tso cai rau feem ntau ntawm cov zaus hla dhau thaum txo qee qhov ntau yam, lub lim band reject ua haujlwm hauv txoj kev sib txawv. Nws tso cai rau feem ntau ntawm cov zaus hla dhau, tab sis txo qee qhov ntau yam ntawm cov zaus kom qis heev.
Qhov tshwj xeeb no ua rau peb lub lim dej tsis lees txais band zoo tagnrho rau cov ntawv thov uas qee qhov zaus yuav tsum tau tshem tawm lossis txo qis. Txawm hais tias koj xav tau tshem tawm cov kev cuam tshuam tsis xav tau lossis lim tawm cov suab nrov tshwj xeeb, peb lub lim dej tsis lees txais band yog tsim los muab kev ua tau zoo thiab kev ua haujlwm raug.
Lub lim dej tsis lees txais band yog ib hom lim dej tshwj xeeb uas siv los nres band, nrog rau nws lub stopband scope me me heev. Qhov no ua kom ntseeg tau tias tsuas yog qhov zaus uas tau teem tseg thiaj li raug txo qis, ua rau cov teeb liab seem seem tsis hloov pauv. Qib kev raug no yog qhov tseem ceeb hauv ntau yam lag luam, suav nrog kev sib txuas lus, kev ua suab, thiab cov cuab yeej siv hluav taws xob.
