Puas yog cov khoom siv hluav taws xob ua kom zoo suab zoo?
Qhov cuam tshuam ntawm cov fais fab kev muab rau ntawm lub suab zoo txhim kho yog ib lub ncauj lus ntawm kev sib tham. Ntau cov suab nyiam thiab cov kws tshaj lij ntseeg tias cov khoom siv fais fab uas muaj peev xwm txhim kho lub suab zoo, thaum lwm tus tuav cov rov qab. Kab lus no yuav tshawb txog qhov cuam tshuam ntawm kev cuam tshuam ntawm cov khoom siv hluav taws xob ntawm lub suab zoo.
Firstly, peb yuav tsum nkag siab txog dab tsi ib sob zog yog. Cov khoom siv fais fab muaj hluav taws xob yog siv cov kab hluav taws xob xws li cov kev tsim tawm, capacitors, thiab inductors los txo cov suab nkauj thiab cov ripple. Piv rau hloov hom hwj huam, cov khoom siv hluav taws xob tau muaj cov zis tawm me me voltage thiab cov suab nrov.
Cov khoom siv suab feem ntau yuav tsum tau ruaj khov, ntshiab, thiab cov suab nrov tsis muaj suab nrov los xyuas kom zoo lub suab ua tau zoo. Nws tsis tuaj yeem tsis lees paub tias kev ruaj ntseg ntawm lub zog muab thiab suab nrov muaj zog tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv suab. Cov khoom siv hluav taws xob tau suav tias yog muaj qee yam zoo hauv qhov no.
Firstly, tus tsim ntawm cov ntaub ntawv fais fab tawm tau zoo txo qhov kev cuam tshuam ntawm cov khoom siv hluav taws xob hauv lub suab. Electromage kev cuam tshuam yog hais txog hluav taws xob hluav taws xob los ntawm lub zog hluav taws xob los ntawm cov khoom siv hluav taws xob, uas yuav cuam tshuam nrog kev xa khoom. Cov kab hluav taws xob thiab cov ntxaij lim dej thiab cov ntxaij lim dej uas siv tau nyob rau hauv cov khoom siv hluav taws xob tawm tau zoo rau cov kev sib cuam tshuam no, yog li kev txhim kho cov kev ua tau zoo ntawm cov cuab yeej siv suab.
Thib ob, cov suab nrov tsawg ntawm cov khoom siv hluav taws xob tau tuaj yeem txo cov teeb liab distortion. Daim paib distortion nyob rau hauv cov khoom siv suab yog qhov kev txhawj xeeb rau ntau lub suab nyiam. Txawm hais tias cov cim distortion yog tshwm sim los ntawm ntau yam, khoom siv fais fab fais fab yog ib qho ntawm cov tseem ceeb. Cov khoom siv hluav taws xob txo cov kev pheej hmoo ntawm cov teeb liab distortion los ntawm kev siv lim capacitors thiab inductors rau lub zog qis.
Ib qho ntxiv, cov khoom siv hluav taws xob tawm tuaj yeem muab cov zis voltage ntau dua. Cov suab tawm suab feem ntau muaj cov kev siv hluav taws xob, tshwj xeeb tshaj yog cov kev siv cov kev sau ua ke siab xws li cov kws tshaj lij cov qauv audio. Cov khoom siv fais fab muaj peev xwm muab cov khoom siv hluav taws xob ruaj khov, kom muaj cov khoom siv ua haujlwm zoo tshaj plaws, zam cov teeb meem xws li compression, distortion, thiab Jitter.
Txawm li cas los xij, tseem muaj qee cov suab sib txawv hais txog kev sib cav sib ceg dhau kev txhim kho lub suab zoo los ntawm cov khoom siv hluav taws xob zoo los ntawm kev siv fais fab. Qee tus neeg ntseeg tias kev txhim kho cov nyhuv ntawm cov khoom siv fais fab tsis tseem ceeb, thiab tej zaum kuj tseem yuav muaj kev puas siab puas ntsws. Lawv ntseeg tias tus tsim ntawm lub suab tawm tswv yim nws tus kheej thiab qhov zoo ntawm nws cov khoom muaj feem cuam tshuam rau lub suab zoo, thiab cov khoom siv hluav taws xob tsis tuaj yeem hloov pauv cov kev ua tau zoo.
Tsis tas li ntawd, piv rau hloov cov khoom siv fais fab, cov kab fais fab khoom muaj hluav taws xob qis dua kev ua haujlwm zoo thiab ntau zog zog. Hloov cov khoom siv fais fab yog ib qho kev hloov hluav taws xob uas siv hluav taws xob xws li kev hloov pauv sai sai, yog li kev txhim kho kev ua hluav taws xob hloov kho lub zog sai sai. Hauv kev sib piv, linear cov khoom siv siv hauv cov khoom siv hluav taws xob linear tsim ntau dua kub thiab haus lub zog ntau dua. Qhov no yuav muaj qhov tsis zoo rau ib puag ncig thiab kev txuag hluav taws xob.
