Rau tus AC integrator, sinusoidal cov tswv yim waveform yuav tsim lwm sine nthwv dej raws li nws cov zis uas yuav yog 90 tawm-ntawm-theem nrog cov tswv yim tsim cov cosine yoj. Ntxiv mus, thaum lub tswv yim yog daim duab peb sab, cov zis waveform kuj yog sinusoidal.
Dab tsi yog qhov txiaj ntsig ntawm qhov sib txawv?
Hauv electronics, tus sib txawv yog ib lub voj voog uas tsim los xws li cov zis ntawm lub voj voog yog kwv yees ncaj ncaj proportional rau tus nqi hloov (lub sij hawm derivative) ntawm cov tswv yim. Tus neeg txawv qhov tseeb tsis tuaj yeem paub lub cev, vim nws muaj qhov nce tsis kawg ntawm qhov zaus tsis kawg.
Yuav ua li cas yog cov zis waveform ntawm txawv?
Raws li qhov sib txawv ntawm Circuit Court muaj qhov tso zis uas yog proportional rau qhov kev hloov pauv, qee qhov qauv waveforms xws li as sine waves, square waves thiab triangular wavesmuab cov waveforms sib txawv ntawm cov zis ntawm qhov sib txawv Circuit Court. … Qhov tseeb rau lub xwmfab yoj tawm tswv yim, tsuas yog luv luv spikes yuav tsum pom.
Yuav ua li cas yog cov zis waveform rau square yoj input siv rau tus sib txawv?
Yog hais tias cov tswv yim rau qhov sib txawv hloov mus rau ib lub voj voog, cov zis yuav yog waveform uas muaj qhov zoo thiab qhov tsis zoo, sib xws rau kev them nqi thiab tawm ntawm lub capacitor, raws li qhia hauv daim duab hauv qab no.
Thaum nkag mus rau qhov sib txawvKo sine yoj tso zis yog?
Teb: Cov zis hluav taws xob yuav yog an inverse cosine wave.
Pom zoo:
Puas yog txawv txawv thiab txawv txawv lossis cov lus sib txawv?
Cov lus txawv txawv thiab txawv txawv yog synonyms, tab sis txawv ntawm nuance. Tshwj xeeb, alienate tej zaum yuav los yog tsis qhia kev sib cais tab sis ib txwm hais txog kev poob kev hlub lossis kev txaus siab. Dab tsi yog lub ntsiab lus ntawm alienate?
Puas tso zis tso zis tsw tsw?
tso zis tsis tas yuav muaj ntxhiab tsw phem. Ntau tus neeg uas muaj teeb meem tswj lub zais zis txwv cov kua dej uas lawv haus hauv kev cia siab tias yuav txo tau qhov teeb meem. Txawm li cas los xij, qhov no ua rau cov zis ua kom muaj zog heev.
Lub tswv yim twg ntawm cov tswv yim cuam tshuam nrog kev sib cav?
Logic (los ntawm Classical Greek λόγος (logos), Ameslikas txhais lo lus, los yog dab tsi yog hais, tab sis los ntawm kev xav los yog vim li cas feem ntau hais tias yog kev kawm. ntawm arguments. Puas yog ceg ntawm kev xav uas tsom mus rau kev tsom xam ntawm kev sib cav?
Puas tso zis tso zis qhia tias mob raum?
Dipstick test. Qee yam kev kuaj dipstick tuaj yeem kuaj xyuas muaj xws li: Acidity (pH) yog qhov ntsuas ntawm cov kua qaub hauv cov zis. A pH uas siab tshaj li qub yuav yog ib qho cim ntawmraum pob zeb, kab mob tso zis, teeb meem raum, lossis lwm yam kab mob.
Puas qhov sib txawv thiab qhov sib txawv ntawm tus qauv muaj cov chav nyob?
Variance yog qhov nruab nrab squared deviations los ntawm qhov txhais tau tias, thaum tus qauv sib txawv yog lub hauv paus square ntawm tus lej no. … qauv sib txawv yog qhia nyob rau hauv tib units raws li tus nqi qub (piv txwv li, feeb lossis meters).
