Dab tsi yog qhov tseem ceeb ntawm cov lim dej

Cov lim dej yog siv dav hauv cov khoom siv hluav taws xob hauv hluav taws xob, nws lub luag haujlwm tseem ceeb yog tshem tawm lossis tshem tawm cov suab nrov, cuam tshuam, lossis tsis xav tau cov khoom siv zaus hauv cov teeb liab, yog li ua kom muaj kev ntseeg siab thiab ua haujlwm ntawm circuits. Yog li ntawd, cov ntxaij lim dej tau siv dav hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
Cov muaj pes tsawg leeg ntawm lub lim muaj xws li cov hauv qab no qhov chaw:
Filter network: Lub lim network yog lub hauv paus tseem ceeb ntawm lub lim dej, muaj ntau yam khoom siv hluav taws xob xws li capacitors, inductors, resistors, thiab lwm yam. Raws li ntau hom lim, lim tes hauj lwm tuaj yeem txais cov qauv sib txawv. Piv txwv li, low-pass filters siv capacitor inductor structures, high pass filters siv inductor capacitor structures, thiab band-pass filters siv multi-stage series los yog parallel capacitor inductor structures.
Lub teeb liab tawm tswv yim thiab cov zis terminals: Cov tswv yim thiab cov zis terminals ntawm lub lim yog cov khoom sib txuas txuas nrog lub lim dej, siv los xa cov teeb liab tawm tswv yim rau lub lim rau kev ua haujlwm thiab tso tawm cov teeb liab ua tiav. Feem ntau, qhov kev tiv thaiv qhov tseem ceeb ntawm cov tswv yim thiab cov khoom tso tawm yuav tsum phim cov yam ntxwv impedance ntawm lub lim network kom tsis txhob muaj teeb meem cuam tshuam thiab poob.
Fais fab mov thiab xaim hauv av: Lub lim yuav tsum muaj lub hwj huam mov kom ua haujlwm zoo, yog li nws yog qhov tsim nyog los txuas cov khoom siv hluav taws xob thiab cov xaim hauv av. Lub zog thiab hauv av xaim yuav tsum ua kom tau raws li qee qhov kev xav tau kom muaj kev ruaj ntseg thiab tiv thaiv kev cuam tshuam ntawm lub lim.
Tswj Circuit Court (optional): Qee cov ntxaij lim dej yuav tsum tau teeb tsa qee qhov kev txwv lossis kho lawv lub xeev kev khiav haujlwm, xws li cov ntxaij lim dej sib txawv ntawm bandwidth, hloov tau cov ntxaij lim dej, thiab lwm yam. Nyob rau ntawm no, nws yuav tsum tau ntxiv qee qhov kev tswj Circuit Court, xws li resistors, capacitors, variable. resistors, keyboards, thiab lwm yam, los kho qhov tsis muaj lossis ua haujlwm ntawm lub lim.
Plhaub thiab connector: Cov lim yuav tsum tau nruab rau hauv lub plhaub thiab txuas nrog lwm cov circuits. Yog li ntawd, nws yog ib qho tsim nyog los xaiv cov casings thiab cov khoom sib txuas kom tau raws li cov kev xav tau ntawm kev sib txuas ntawm cov tshuab thiab hluav taws xob.
Cov kev sib xyaw ntawm cov lim dej feem ntau suav nrog ntau yam hauv paus, xws li cov lim dej, cov teeb liab tawm tswv yim thiab cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov xaim hauv av, tswj Circuit Court (yeem), vaj tse thiab connector. Cov muaj pes tsawg leeg ntawm ntau hom lim yuav sib txawv.
