Suab nrov lim dej lim dej ntawm donies hauv cov neeg hais lus ntse

1, cov ntsiab cai yooj yim thiab cov yam ntxwv ntawm dodes
Cov tub ntxhais ntawm Diode, ua cov cuab yeej ua haujlwm semiconduct nrog unidirectional conductivity, lus dag hauv tus qauv tshwj xeeb ntawm pn hlws ris. Thaum cov diode yog tom ntej kev sib ntxub, uas yog, lub zog hluav taws xob tau thov rau daim ntawv pninal thiab cov tshuab hluav taws xob tsis zoo, tso cai tam sim no ntws mus. Thaum lub sij hawm rov qab hais txog kev tsis ncaj ncees, cov cab kuj nyob hauv cov kev sib tshuam PN yog qhov tsis kam lees, sib sau ua lub xeev siab uas tiv thaiv kev ntws tam sim no. Cov kev coj tsis zoo no ua rau muaj kev ua haujlwm zoo rau kev ua haujlwm xws li kev tshuaj xyuas ntau yam xws li, nrhiav kom zoo, kev ua kom zoo, thiab lwm yam.
Nyob rau hauv cov nqe lus ntawm cov suab nrov lim, diodes tsuas yog siv lawv cov kev coj ua tsis zoo thiab cov neeg nonlinear mus rau suab nrov. Thaum lub suab nrov ntaus cim rau hauv Circuit Court, donges tuaj yeem kaw lawv hauv ib qho kev taw qhia, yog li txo cov suab nrov. Ib qho ntxiv, diodes tseem tuaj yeem tsim tsa suab nrov los ntawm Peak clipping thiab txwv. Thaum lub suab nrov nrov tshaj li cov ntawv hluav taws xob rau pem hauv ntej ntawm Diode, cov diode yuav pib ua, clipping thiab txwv lub teeb liab, yog li txo qhov nrov ntawm lub suab nrov.
2, Cov peev txheej thiab cov peev xwm ntawm suab nrov hauv cov neeg hais lus ntse
Cov cuab yeej ntse suab ntse yog muaj ntau yam ntawm kev cuam tshuam nrov nrov thaum lub sijhawm ua haujlwm. Cov suab nrov no tuaj yeem los ntawm kev cuam tshuam hluav taws xob hauv lub suab, thiab lwm yam suab nrov, ua rau muaj kev sib cav sib ceg, ua rau lub suab nrov xws li, ua kom muaj zog, distortion thiab lwm yam teeb meem.
Qhov cuam tshuam ntawm cov suab nrov ntawm cov neeg hais lus ntse yog qhov tseem ceeb hauv qab no: Ua ntej, nws txo lub suab zoo, ua rau lub suab kaw suab thiab tsis meej; Qhov thib ob yog kom nce qhov distortion ntawm lub teeb liab suab, ua lub suab zoo hnyav thiab tsis zoo; Qhov teeb meem thib peb yog kev cuam tshuam ntawm cov cim qhia tawm suab, uas tuaj yeem qeeb cov lus teb uas tsis tshua hais ntawm cov teeb meem ntse xws li taug kev thiab qeeb.
3, Daim ntawv thov ntawm dodes nyob rau hauv lub suab nrov lim nyob rau hauv lub tshuab txawj ntse audio
Hauv cov neeg hais lus ntse, cov kev siv hluav taws xob feem ntau yog siv los ua cov lim lim rau kev tsim kho thiab tshem tawm cov cim suab nrov. Diode lim tuaj yeem ua kom tsis muaj zog lossis tshem tawm qhov siab - cov qauv kev ua haujlwm los ntawm cov qauv sib txawv ntawm cov qauv sib txawv thiab ua tiav cov ntsiab lus lim.
Fais Fab Lim
Nyob rau hauv lub zog hluav taws xob ntawm cov neeg hais lus ntse, cov lim dai yog feem ntau siv los ua cov ntxaij lim dej kom lim kom lim tawm ntawm lub siab {} suab nrov thiab swb hauv lub zog hluav taws xob. Los ntawm kev xaiv cov qauv kev tsim nyog
suab lim
Nyob rau hauv lub suab sib koom tes ntawm cov neeg ntse hais, dirode lim dioct kuj tseem tuaj yeem siv los tshem tawm cov suab nrov thiab cuam tshuam hauv cov teeb liab suab. Los ntawm kho cov tsis sib xws thiab Circuit Court cov qauv xaiv thiab lim ntawm cov teeb tsa lub suab tuaj yeem ua tiav, yog li kev txhim kho lub suab meej thiab muaj kev zoo siab ntawm suab zoo.
Cov suab nrov Ris
Hauv kev tshawb pom kev paub txog kev thaij duab ntawm cov neeg hais lus ntse, photodiode cov suab nrov lim dej kuj tau ua lub luag haujlwm tseem ceeb. Hom kev lim no zoo rau kev cuam tshuam lossis tshem tawm cov khoom siv hluav taws xob hauv cov paib zis los ntawm kev siv cov khoom siv siv hluav taws xob lim thiab software algorithm. Cov khoom siv kho vajtse lim cov lus xaiv cov lim lim uas tsim nyog thiab cov ntsuas kom xaiv cov zaus ntawm lub teeb liab; Qhov software algorithm feem siv cov teeb liab kev siv hluav taws xob ua rau pom zoo thiab cov txheej txheem sau cov suab nrov thiab cuam tshuam. Lub suab nrov no txo ​​cov lim lim yog qhov tseem ceeb hauv kev txhim kho cov kev kuaj pom qhov tseeb thiab kev ruaj ntseg ntawm cov tshuab ntse audio.
4, cov nyhuv tiag tiag thiab cov txiaj ntsig ntawm diode suab nrov lim ua haujlwm
Lub suab nrov lim ntawm diodes nyob rau hauv cov neeg hais lus ntse muaj qhov cuam tshuam tseem ceeb. Los ntawm kev siv dire lim, nws yog qhov ua tau zoo txo ​​lub suab hluav taws xob, thiab cuam tshuam los ntawm lwm cov cim hluav taws xob, txhim kho lub suab huv thiab pom tseeb ntawm suab zoo. Lub caij no, dide lim kuj muaj qhov zoo ntawm cov qauv yooj yim, tus nqi qis, thiab kev siv tau yooj yim, ua rau lawv siv dav hauv cov cuab yeej ntse suab.
Ib qho ntxiv, dide lim kuj muaj qee qib ntawm kev yoog tau thiab hloov tau. Los ntawm kho cov tsis sib xws thiab Circuit Court qauv ntawm lub lim, nws tuaj yeem hloov kho cov suab sib txawv thiab cov cim teeb liab ib puag ncig, yog li ua tiav cov nyhuv filting zoo tshaj plaws. Qhov no hloov tau thiab hloov tau zoo dire cov ntxaij lim dej muaj cov kev thov cuam tshuam dav hauv cov ntawv thov kev cia siab hauv cov khoom siv.
