8. Vim li cas nws nyuaj rau tuav Barkhausen mob rau oscillation? Kev piav qhia: Barkhausen mob |Aß|=1 feem ntau nyuaj rau kev tswj hwm hauv Circuit Court raws li tus nqi ntawm A thiab ß sib txawv vim qhov ntsuas kub hloov pauv, kev laus ntawm cov khoom, kev hloov pauv ntawm cov khoom siv hluav taws xob thiab lwm yam
Qhov xwm txheej Barkhausen yog dab tsi rau kev ua haujlwm ruaj khov?
hu ua "Barkhausen criterion" rau kev ua haujlwm ruaj khov. … Qhov kev ntsuas Barkhausen hais tias: • Lub voj nce yog sib npaug rau kev sib koom ua ke hauv qhov loj kawg, uas yog, | β Ib |=1 thiab Page 2 • Cov theem hloov ntawm lub voj yog xoom los yog ib qho ntau ntau ntawm 2π radian (180 °) i.e.
Yuav ua li cas thiaj ua tiav oscillations?
Rau qhov ntawd, tsuas yog nco qab txog qhov tsim nyog ntawm oscillations. Txhawm rau pib oscillations, tag nrho cov theem hloov ntawm lub voj voog yuav tsum yog 360 ° thiab qhov loj ntawm lub voj nce yuav tsum siab dua ib qho.
Cov qauv twg yuav tsum txaus siab rau lub oscillator?
Gain in Oscillators:
Tus oscillator nce yuav tsum sib npaug ib qho (Aβ=1–180°) ntawm qhov oscillation zaus Lub voj voog yuav ruaj khov thaum qhov nce siab tshaj ib qho thiab oscillations cease. Thaum qhov nce siab tshaj ib qho nrog rau theem hloov ntawm -180 °, cov cuab yeej nquag uas tsis yog-linearity txo qhov nce mus rau ib qho.
Dab tsi yog ob qho xwm txheej rau oscillation?
Cov kev cai yooj yim rau kev oscillations yog: Lub oscillator xav kom muaj kev nthuav dav los muab qhov tsim nyog nce rau lub teeb liab . Yuav kom txhawb nqa oscillations, oscillator xav tau kev rov tsim dua tshiab.

Vim li cas nws tseem ceeb uas lub voj voog ntawm tes tswj tau zoo thiab tswj tau?
Kev tswj lub voj voog ntawm tes yog tsim nyog rau ob peb lub laj thawj. Ua ntej, yog tias lub voj voog ntawm tes tsis tswj hwm, cov hlwb tuaj yeem ua rau kev faib tawm ntawm tes … Thib ob, kev tswj hwm sab hauv ntawm lub voj voog ntawm tes yog qhov tsim nyog rau kev teeb tsa los ntawm ib theem mus rau lwm lub sijhawm.
Leej twg tseem ceeb xaiv tus thawj tswj hwm hauv kev tswj hwm tus thawj tswj hwm?
Cov neeg txhawb nqa feem ntau thov plaub qhov txiaj ntsig zoo rau kev xaiv tsa thawj tswj hwm: kev xaiv tsa ncaj qha - hauv kev xaiv nom tswv, tus thawj tswj hwm feem ntau raug xaiv ncaj qha los ntawm cov neeg. Qhov no ua rau tus thawj tswj hwm lub hwj chim tshwm sim rau qee qhov ua tau raug cai ntau dua li tus thawj coj tau xaiv tsis ncaj.
