Band Reject Filter
| Leader-mw | Taw qhia rau band rejection filter |
Cheng du thawj coj microwave Tech., (tus thawj coj-mw) Band Reject Filter (tseem hu ua bandstop filter lossis BSF), ib qho tshwj xeeb tivthaiv uas ua lub luag haujlwm tseem ceeb hauv kev tswj cov zaus ntawm lub teeb liab. Tsis zoo li ib qho kev lim band-pass lim, uas tso cai rau feem ntau ntawm cov khoom siv zaus dhau los thaum ua kom muaj qee qhov ntau, lub band tsis kam lim ua haujlwm hauv qhov sib txawv. Nws tso cai rau feem ntau ntawm cov khoom siv zaus dhau mus, tab sis attenuates ib qho tshwj xeeb ntawm cov khoom siv zaus mus rau qib qis heev.
Cov yam ntxwv tshwj xeeb no ua rau peb cov qhab tsis lees txais qhov zoo tshaj plaws rau cov ntawv thov uas qee zaus yuav tsum tau muab tshem tawm lossis txo qis. Txawm hais tias koj yuav tsum tshem tawm cov kev cuam tshuam uas tsis xav tau lossis lim tawm cov suab nrov tshwj xeeb, peb lub lim dej tsis lees paub yog tsim los ua kom muaj kev ua tau zoo tshwj xeeb thiab raug.
Lub band tsis kam lim yog ib hom tshwj xeeb ntawm band-stop lim, nrog nws qhov kev txwv tsis pub muaj qhov me me heev. Qhov no ua kom ntseeg tau tias tsuas yog lub hom phiaj ntau zaus tau txais txiaj ntsig zoo, tawm hauv cov teeb liab tas li. Qib no ntawm qhov tseeb yog qhov tseem ceeb hauv ntau qhov kev lag luam, suav nrog kev sib txuas lus, kev ua suab, thiab kev ntsuas hluav taws xob.
