Lub separator ua haujlwm li cas?

1, Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab cais
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub separator yog nyob ntawm qhov txawv thiab rho tawm cov yam ntxwv sib txawv ntawm lub teeb liab. Tshwj xeeb, tus separator soj ntsuam thiab ua cov txheej txheem tsis xws li zaus, amplitude, thiab theem ntawm cov teeb liab tawm tswv yim kom cais cov khoom sib txawv ntawm lub teeb liab. Qhov no feem ntau muaj cov txheej txheem xws li teeb liab lim, hloov kho, thiab demodulation.
Thaum lub sij hawm filtering txheej txheem, lub separator siv lub selectivity ntawm lub lim rau txawv zaus Cheebtsam los lim tawm cov pliaj zaus Cheebtsam nyob rau hauv lub teeb liab, yog li tau txais qhov xav tau tshwj xeeb zaus ntau lub teeb liab. Cov txheej txheem modulation thiab demodulation muaj cov teeb liab hloov dua siab tshiab thiab rho tawm, thauj cov ntaub ntawv mus rau tus cab kuj los ntawm kev hloov kho, thiab tom qab ntawd rho tawm cov ntaub ntawv los ntawm cov cab kuj los ntawm demodulation.
2, Hom kev sib cais
Separators tuaj yeem muab faib ua ntau hom raws li lawv cov qauv kev ua haujlwm thiab daim ntawv thov scenarios. Cov hom sib cais muaj xws li zaus cais, polarization separators, lub zog cais, thiab lwm yam.
Frequency separators feem ntau yog siv los cais cov cim ntawm ntau zaus. Nws feem ntau muaj ib lossis ntau lub lim dej, txhua qhov sib txuas rau ib qho kev sib txawv, kom ua tiav kev sib cais ntawm cov cim nrog ntau zaus.
Polarization separators yog siv los ua cov teeb liab nrog ntau hom polarization. Hauv kev sib txuas lus wireless thiab kev sib txuas lus satellite, cov teeb liab feem ntau siv ntau txoj kev polarization xws li kab rov tav polarization thiab ntsug polarization. Polarization separator tuaj yeem cais cov cim raws li lawv cov yam ntxwv polarization kom tau raws li qhov xav tau ntawm cov tshuab txais sib txawv.
Lub zog sib cais feem ntau yog siv los faib lub zog ntawm cov teeb liab tawm tswv yim rau ntau qhov chaw tso zis. Hauv kev faib hluav taws xob sib txuas, lub zog hluav taws xob sib cais ua lub luag haujlwm tseem ceeb hauv kev ua kom lub zog sib txawv ntawm cov khoom siv hluav taws xob.
3, Daim ntawv thov teb ntawm separators
Separators ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Hauv kev sib txuas lus, cov khoom sib cais tau siv dav hauv kev ua cov teeb liab thiab cov txheej txheem sib kis kom ruaj khov thiab ua haujlwm tau zoo. Hauv kev tshaj tawm xov xwm thiab TV, cov khoom sib cais yog siv los cais cov khoom sib txawv xws li suab thiab yees duab hauv cov teeb liab sib xyaw rau kev rov ua dua thiab ua tiav. Hauv kev ua haujlwm ntawm lub teeb liab, cov khoom sib cais yog siv los rho tawm cov ntaub ntawv tseem ceeb ntawm cov teeb liab, txo cov suab nrov thiab cuam tshuam, thiab txhim kho cov teeb liab zoo.
Tsis tas li ntawd, nrog kev txhim kho sai ntawm cov thev naus laus zis xws li Is Taws Nem ntawm Cov Khoom thiab cov tsev ntse, kev siv cov khoom sib cais hauv cov tshuab ntse hauv tsev, sensor tes hauj lwm, thiab lwm yam kev lag luam tau nce zuj zus. Los ntawm kev sib cais thiab ua tiav cov cim qhia los ntawm kev sib cais, kev tswj xyuas ntse thiab kev tswj xyuas cov khoom siv hauv tsev zoo tuaj yeem ua tiav, txhim kho lub neej zoo.
