Txawm li cas los, nyob rau hauv lub suab band , a nqa lim muaj siab thiab lowfrequencies uas tej zaum tsuas yog semitones sib nrug.
Hais txog qhov no, dab tsi yog filtering nyob rau hauv lub teeb liab ua?
Hauv teeb liab ua , a lim yog tus ntaus ntawv txheej txheem uas tshem tawm qee yam tsis xav tau lossis cov yam ntxwv ntawm a teeb liab . Lim yog ib chav kawm ntawm teeb liab ua , lub defining feature ntawm lim yog qhov ua tiav los yog ib nrab kev tsuj ntawm qee yam ntawm cov teeb liab.
Qhov thib ob, dab tsi yog attenuation band? Yog li tus passband ripple yog tus nqi ntawm kev hloov pauv hauv lub amplitude, nyob rau hauv tus txheej txheem passband ntawm lub lim, thiab nres band attenuation yog qhov tsawg kawg nkaus attenuation theem nrog rau kev tsis lees paub band ntawm lub lim.
Tsis tas li ntawd, vim li cas cov ntxaij lim dej siv hauv kev ua cov teeb liab digital?

Dab tsi ntawm cov hauv qab no yog qhov zoo ntawm kev siv cov khoom siv pom kev hauv kev hais lus?
Qhov txiaj ntsig tseem ceeb ntawm kev siv cov khoom siv pom hauv koj cov lus hais yog tias lawv ua kom cov neeg tuaj saib muaj kev txaus siab, hloov kev mloog ntawm tus neeg hais lus, thiab ua rau tus neeg hais lus muaj kev ntseeg siab ntau dua hauv kev nthuav qhia tag nrho
Vim li cas tsis muaj teeb liab hauv kuv lub xov tooj?
Hloov kho koj lub network kev sib txuas los ntawm kev hloov tawm thiab rov pib koj lub cuab yeej. Yog tias qhov kev pab them nqi zoo li qub, tsis muaj kev saib xyuas lossis teeb meem hauv koj cheeb tsam thiab rov pib koj lub xov tooj tsis tau ua haujlwm: Tej zaum koj lub SIM lossis xov tooj tsis raug. Txhawm rau kuaj xyuas SIM yuam kev, sim koj SIM hauv lwm lub xov tooj
Lub teeb liab rau lub suab nrov yog dab tsi thiab vim li cas nws tseem ceeb?
Lub teeb liab rau lub suab nrov piv yog qhov tseem ceeb vim hais tias hauv kev sib txuas lus peb lub ntsiab tseem ceeb yog lub teeb liab tab sis thaum lub sij hawm kis tau tus mob tau cuam tshuam los ntawm qee lub suab nrov. Thaum kawg tau txais peb xav kom muaj tib lub teeb liab sib kis, kom ua tiav qhov no lub suab nrov yuav tsum tau txo qis thiab ntawm no SNR ua lub luag haujlwm tseem ceeb
Vim li cas cov roj teeb nres nres?
Tab sis raws li kev tshawb fawb los ntawm US Department of Energy, vim li cas cov roj teeb lithium-ion poob lawv cov nqi dhau sijhawm yog vim muaj cov tshuaj tsis haum tshuaj. Nws pib nrog cov electrodes, uas feem ntau suav nrog npib tsib xee hauv lawv cov khoom pleev xim
Dab tsi yog kev siv cov ntawv cim kev cai li cas koj nkag mus rau hauv Apex cov chav kawm thiab hauv Visualforce nplooj ntawv?
Cov ntawv sau kev cai tso cai rau cov neeg tsim khoom tsim cov ntawv thov ntau hom lus los ntawm kev nthuav qhia cov ntaub ntawv (piv txwv li, pab cov ntawv lossis cov lus yuam kev) hauv tus neeg siv hom lus. Cov ntawv sau kev cai yog cov ntawv sau muaj txiaj ntsig uas tuaj yeem nkag tau los ntawm Apex cov chav kawm, nplooj ntawv Visualforce, lossis cov khoom siv xob laim
