2024 Tus sau: Lynn Donovan | [email protected]. Kawg hloov kho: 2023-12-15 23:47
Stands rau "Digital-rau-Analog Converter" thiab feem ntau pronounced " dac "Xim khoos phis tawj tsuas yog lees paub cov ntaub ntawv digital, cov khoom tsim tawm los ntawm khoos phis tawj yog feem ntau nyob rau hauv cov hom ntawv. Txawm li cas los xij, qee cov khoom siv tso tawm tsuas yog lees txais cov tswv yim analog, uas txhais tau tias digital-rau-analog converter, lossis DAC , yuav tsum tau siv.
Ntawm no, dab tsi yog hom DAC?
Muaj ob hom D/A converters:
- Qhov hnyav Resistor lossis Resistive Divider hom.
- R-2R ntaiv hom.
Ib sab saum toj no, DAC tseem ceeb npaum li cas? ib qho zoo dac nce qhov zoo, thiab ntim. Nws pib siv txoj haujlwm ntawm kev hloov mus rau analog daim ntawv ntawm PC lub suab paj nruag rau ib qho khoom siv sawv ntsug. Qee zaum siv AMP yam tsis muaj a dac tej zaum yuav ua rau lub suab nrov dawb nyob ntawm qhov zoo ntawm koj daim npav suab.
Tib neeg kuj nug tias, siv DAC yog dab tsi?
Txoj haujlwm ntawm DAC yog coj ib tug digitally storedrecording thiab tig nws rov qab mus rau hauv ib tug analog teeb liab. Ua li ntawd, nws yuav tsum tau txhais cov khoom ntawm cov ntaub ntawv los ntawm cov ntaub ntawv digital mus rau hauv lub teeb liab hluav taws xob ntawm ntau txhiab lub sij hawm ib ob, txwv tsis pub hu ua cov qauv.
DAC txhais li cas?
Ib tug digital-rau-analog converter ( DAC ) yog ib qho khoom siv, feem ntau muaj ib lub nti, rau kev hloov binary ordigital code rau hauv lub teeb liab analog. A DAC ntaus ntawv converts anabstract finite tus naj npawb, feem ntau yog ib tug taag-point binarynumber, mus rau hauv ib tug meej lub cev sib txawv xws li voltage orpressure.

Rau cov khoom tsis sib xws hauv ib daim ntawv teev npe (raws li hauv Nieuwenstein & Potter's thwmsim, 2006) tag nrho daim ntawv tshaj tawm raug cuam tshuam los ntawm tag nrho cov khoom hauv ib ntu, qhov kev tshaj tawm ib nrab tsuas yog cuam tshuam tsawg kawg nkaus los ntawm tag nrho cov khoom, yog tias tsuas yog ob qho yuav tsum tau ua. qhia
Dab tsi yog tag nrho cov kab kev sib txuas lus uas xav tau rau kev sib txuas tag nrho rau taw tes network ntawm tsib lub khoos phis tawj rau lub khoos phis tawj?
Tus naj npawb ntawm cov kab sib txuas lus uas yuav tsum tau muaj rau kev sib txuas tag nrho ntawm qhov taw tes rau-taw tes ntawm yim lub khoos phis tawj yog nees nkaum yim. Ib tug tag nrho txuas cuaj lub computer network yuav tsum tau peb caug rau kab. Ib tug tag nrho txuas kaum lub computer network yuav tsum tau plaub caug tsib kab

Dab tsi yog qhov txawv ntawm daim ntawv pov thawj tus kheej thiab daim ntawv pov thawj CA?
Qhov kev ua haujlwm tseem ceeb ntawm daim ntawv pov thawj tus kheej kos npe thiab daim ntawv pov thawj CA yog tias nrog tus kheej kos npe, tus browser feem ntau yuav muab qee yam yuam kev, ceeb toom tias daim ntawv pov thawj tsis tau muab los ntawm CA. Ib qho piv txwv ntawm qhov yuam kev daim ntawv pov thawj tus kheej tau pom nyob rau hauv lub screenshot saum toj no
Daim ntawv tag nrho ntawm SMPP yog dab tsi?
Cov Lus Qhia luv luv Peer-to-Peer (SMPP) hauv kev lag luam kev sib txuas lus yog qhib, kev lag luam tus qauv raws tu qauv tsim los muab cov ntaub ntawv sib txuas lus hloov tau yooj yim rau kev hloov cov ntaub ntawv luv luv ntawm Sab Nraud Short Messaging Entities (ESMEs), Routing Entities (REs) thiab SMSC
