Hauv electronics, a txwv yog ib lub voj voog uas tso cai rau cov teeb liab hauv qab ib qho kev tawm tswv yim zog los yog theem kom dhau tsis muaj kev cuam tshuam thaum attenuating (qis) lub ncov ntawm cov cim muaj zog uas tshaj qhov pib. Kev txwv yog ib qho txheej txheem uas qhov amplitude ntawm lub teeb liab tiv thaiv kom tsis pub dhau tus nqi predetermined.
Ntxiv mus, lub zog limiter ua haujlwm li cas?
Ib hluav taws xob limiter yog ib lub cuab yeej uas lub tuam txhab faib khoom nruab rau ntawm koj lub 'meter' tom qab tau txais 'De-energize for Non-Payment' thov los ntawm koj lub khw muag khoom. Yog ntau dhau hluav taws xob yog siv ib zaug, lub txwv yuav 'tawm mus' thiab tua koj zog.
Tsis tas li ntawd, dab tsi yog limiter diode? Cov Diode Clipper, tseem hu ua a Diode Limiter , yog yoj shaping circuit uas siv lub tswv yim waveform thiab clips los yog txiav tawm nws sab saum toj ib nrab, hauv qab ib nrab los yog ob qho tib si halves ua ke. Qhov kev txiav tawm ntawm cov teeb liab tawm tswv yim no ua rau cov zis tawm suab uas zoo ib yam li cov qauv sib txawv ntawm cov tswv yim.
Ua li no, tus limiter ua li cas?
Suab Cov txwv . A txwv yog ib hom compressor tsim los rau ib lub hom phiaj tshwj xeeb - kom txwv cov theem ntawm lub teeb liab mus rau ib qho chaw pib. Thaum lub compressor yuav pib smoothly txo qhov nce siab tshaj qhov pib, a txwv yuav luag tag nrho tiv thaiv ib qho kev nce ntxiv tshaj qhov pib.
Dab tsi yog brickwall limiter?
A txwv teeb tsa nrog qhov sib piv siab (feem ntau "infinity": 1) uas nyuaj "qab nthab" raug txwv rau theem teeb liab - thaum lub teeb liab ncav cuag qhov pib, nws tuaj yeem mus tsis tau ntxiv. Brickwall txwv feem ntau yog siv los tiv thaiv digital overs thiab rau lwm hom kev tiv thaiv overload.
