Yog tias koj lub mloog pob ntseg suab tsis zoo, yog tias koj lub guitar zoo li tsis muaj sia, lossis koj lub suab tso suab hauv tsev tsis muaj av nkos, tej zaum koj yuav cuam tshuam nrog cov zis impedance. Nov yog yam koj yuav tsum paub txog qhov tso zis impedance thiab vim li cas nws thiaj li rub ntawm koj lub tso suab.
Qhov Tawm Tawm Impedance yog dab tsi?
Yuav kom nkag siab qhov tso tawm impedance, peb yuav tsum tau teeb tsa qee qhov kev tsim hluav taws xob yooj yim. Thaum koj hloov hluav taws xob los ntawm qhov chaw mus rau qhov chaw ntawm ib lub xaim lossis lwm yam khoom siv hluav taws xob, tsis yog txhua lub zog tau dhau los. Xav txog nws zoo li nchuav dej kub tshaj kas fes thiab lim thaum sawv ntxov; feem ntau ntawm cov dej nkag mus, tab sis tsis yog tag nrho nws.
Yog li, koj yuav poob qee lub zog, feem ntau nyob rau hauv daim ntawv ntawm tshav kub. Qhov no hu ua resistance.
Tom ntej no, koj yuav tsum xav txog tsuas yog muaj hluav taws xob ntau uas koj tuaj yeem yuam rau hauv ib qho khoom siv. Nws zoo li dej ntws los ntawm cov yeeb nkab; loj los yog me me, muaj ib qho chaw uas cov dej hauv cov yeeb nkab yuav tsum ntws tawm ua ntej ntau tuaj yeem nkag tau. Qhov no hu ua capacitance.
Tau nrog cov yeeb nkab sib piv, cov dej nyiam ntws mus rau hauv ib qho kev taw qhia. Yog tias koj xav hloov txoj kev ntawd, nws yuav siv sijhawm me ntsis kom cov dej ntws rov qab. Ib yam yog qhov tseeb ntawm cov hluav taws xob tam sim no, hu ua inductance, thiab nws tseem ceeb tshwj xeeb rau cov khoom siv hloov pauv tam sim no.
Impedance yog cov lej ntawm cov xwm txheej no, uas suav nrog kev lej me ntsis. Cov zis impedance tsuas yog ntau npaum li cas impedance nyob rau ntawm "tawm" qhov kawg ntawm lub kaw lus, xws li lub mloog pob ntseg los yog kev sib txuas cable.
Vim li cas cov zis Impedance tseem ceeb?
Cia peb rov qab mus rau peb cov yeeb nkab sib piv. Cia peb hais tias koj xav txuas koj cov yeeb nkab ua haujlwm zoo, nrog cov dej ntws txaus, mus rau lwm cov yeeb nkab. Yog tias koj tsuas yog txuas ib lub yeeb nkab me me rau hauv qhov ntawd, nws yuav ua rau lub zog loj heev rau lub cev thiab tej zaum yuav tawg cov yeeb nkab. Piv txwv li, yog tias koj txuas lub kav dej loj dua rau hauv, koj yuav tau txais cov dej ntws xwb thaum koj qhib lub faucet.
Hauv cov khoom siv hluav taws xob, qhov no yog qhov cuam tshuam los ntawm, piv txwv li, av nkos suab lossis tsis muaj suab ntawm txhua tus neeg hais lus, lossis txawm tias koj ntsaws rau hauv lub kaw lus overloading. Qhov no yog vim li cas high-end audio systems feem ntau suav nrog amplifier; lawv xav tau kev txhawb zog kom haum rau impedance.
Kuv Puas Yuav Tsum Tau Xam Cov Tso Tawm Impedance Kuv tus kheej?
Tshwj tsis yog tias koj tab tom tsim kho koj tus kheej lub voj voog, kev nqa hnyav tau ua tiav rau koj. Txhua yam khoom siv uas qhov tso tawm impedance cuam tshuam, xws li amplifier lossis ib pawg neeg hais lus, yuav muaj qhov tso zis impedance thiab input impedance raws li ib feem ntawm tag nrho cov lus qhia ntawm lub cuab yeej. Koj tuaj yeem pom cov no hauv online lossis hauv cov neeg siv phau ntawv. Feem ntau, cov khoom siv pheej yig dua, xws li pob ntseg pob ntseg, yuav muaj qhov cuam tshuam qis dua li lub khob khob kim kim.
Txawm li cas los xij, nco ntsoov tias qhov no yuav tsum tau "muab" hla tag nrho cov saw ntawm cov khoom siv. Piv txwv li, yog tias koj muaj lub suab nrov, lub cable, thiab cov neeg hais lus, cov zis impedance ntawm tus neeg uas ua ntawv yuav tsum phim cov input impedance ntawm lub cable, thiab cov zis impedance ntawm cable yuav tsum phim lub input impedance ntawm tus neeg hais lus.
