Kev nkag siab thiab txheeb xyuas qhov ua tau zoo ntawm Circuit Court yog qhov tseem ceeb hauv kev ua haujlwm ntawm hluav taws xob engineering. Oscilloscope, raws li lub cuab yeej muaj zog, muab cov engineers nrog kev txhawb nqa tseem ceeb hauv kev daws teeb meem, kev tsim kho kom zoo, thiab kev txheeb xyuas qhov system los ntawm kev ntes, nthuav tawm, thiab tshuaj xyuas cov ntaub ntawv waveform ntawm hluav taws xob teeb liab. Tsab ntawv xov xwm no yuav qhia txog qhov tseem ceeb ntawm oscilloscope hauv kev tshuaj xyuas hluav taws xob ua haujlwm thiab sib tham txog yuav ua li cas waveform tsom xam qhia cov lus zais hauv circuits.
Lub hauv paus ntsiab lus ntawm Waveform Observation
Waveform graphs tso tawm ntawm oscilloscopes feem ntau muaj kab rov tav axis sawv cev rau lub sijhawm thiab ntsug axis sawv cev rau qhov voltage. Los ntawm kev kho qhov chaw ntawm oscilloscope, peb tuaj yeem hloov kho lub sijhawm thiab qhov ntsuas hluav taws xob kom zoo dua saib cov ntsiab lus waveform. Tsis tas li ntawd, oscilloscopes feem ntau muab kev ua haujlwm los pab ntes cov ntaub ntawv waveform thaum muaj xwm txheej tshwj xeeb.
Kev sib raug zoo ntawm Waveform Shapes thiab Circuit Court yam ntxwv
Ntau hom circuits tsim cov duab waveform sib txawv, uas qhia txog ntau yam hauv Circuit Court. Piv txwv li:
●Sine waveforms qhia tias muaj cov teeb liab AC, nrog rau lawv qhov amplitude, zaus, thiab theem cuam tshuam txog cov yam ntxwv ntawm qhov chaw hluav taws xob lossis cov teeb liab generators.
●Square lossis mem tes waveforms qhia tias muaj cov cim digital, feem ntau pom nyob rau hauv kev hloov tus cwj pwm lossis cov teeb liab mem tes xa hauv digital circuits.
● Lub sij hawm nce thiab lub caij nplooj zeeg ntawm cov waveforms qhia txog lub teeb liab kis ceev thiab lub sij hawm teb ntawm circuits, uas yog ib qho tseem ceeb rau kev ntsuam xyuas cov teeb liab kis ceev thiab circuit bandwidth.
Kev ntsuam xyuas lub teeb liab kev ruaj ntseg thiab distortion
Los ntawm kev soj ntsuam cov ntaub ntawv waveform, peb tuaj yeem ntsuam xyuas qhov ruaj khov thiab kev cuam tshuam ntawm cov teeb liab:
●Stable waveforms qhia cov qauv nruam thiab du, qhia tias cov teeb liab kis tau yam tsis muaj kev cuam tshuam loj lossis cuam tshuam.
●Distorted waveforms tuaj yeem pom cov duab deformations, suab nrov, lossis tsis ruaj khov amplitude, uas tuaj yeem tshwm sim los ntawm kev ua yuam kev, suab nrov, lossis cuam tshuam hauv Circuit Court.
Kev txheeb xyuas zaus Spectrum yam ntxwv
Ntxiv nrog rau lub sij hawm-domain tsom xam, oscilloscopes tuaj yeem ua qhov kev tshuaj ntsuam xyuas zaus los tshuaj xyuas cov yam ntxwv ntawm zaus:
● Siv Fourier hloov pauv ua haujlwm, cov teeb liab tuaj yeem hloov pauv mus rau hauv cov kab hluav taws xob ntau zaus, qhia txog ntau yam zaus muaj nyob hauv lub teeb liab. Qhov no yuav pab txheeb xyuas cov yam ntxwv zaus thiab nkag siab txog cov khoom xws li cov zaus zaus, kev sib haum xeeb, thiab suab nrov.
● Amplitude thiab theem cov ntaub ntawv ntawm cov zaus spectrum muab cov ncauj lus kom ntxaws tsom xam, pab kom nkag siab txog kev faib cov zaus thiab theem kev sib raug zoo ntawm cov khoom sib txawv.
Kev siv Triggering Functions los ntes cov xwm txheej tshwj xeeb
Oscilloscope triggering functions pab kom ntes cov ntaub ntawv waveform thaum muaj xwm txheej tshwj xeeb tshwm sim:
● Kev teeb tsa cov xwm txheej tshwm sim, xws li cov qib hluav taws xob ua kom muaj zog, qhov cuam tshuam ntawm ntug, lossis qhov chaw cuam tshuam, tso cai kom raug ntes ntawm cov ntaub ntawv waveform thaum muaj xwm txheej txaus siab tshwm sim.
● Kho cov haujlwm ua haujlwm pab txheeb xyuas lub sijhawm tshwm sim thiab cov yam ntxwv waveform ntawm cov xwm txheej tshwj xeeb kom raug, ua kom muaj teeb meem hauv cheeb tsam lossis kev tsom xam teeb liab.
Daim duab waveform yog cov ntsiab lus tseem ceeb uas pom los ntawm oscilloscope. Los ntawm kev soj ntsuam thiab txheeb xyuas cov ntaub ntawv waveform, engineers tuaj yeem nkag siab tob txog kev ua haujlwm thiab kev coj tus cwj pwm ntawm cov tshuab hluav taws xob. Kev soj ntsuam kom zoo thiab kev txhais cov duab waveform tuaj yeem pab cov engineers sai sai txheeb xyuas cov teeb meem, ntsuas kev ua tau zoo, thiab txhim kho cov qauv tsim, yog li ua kom ruaj khov thiab ua haujlwm tau zoo ntawm cov tshuab hluav taws xob.
