Analog thiab Digital signals yog cov hom teeb liab nqa cov ntaub ntawv. Qhov loj qhov sib txawv ntawm ob leeg teeb liab yog tias analog signals uas muaj hluav taws xob tsis tu ncua, thaum digital signals hluav taws xob tsis tu ncua.
Ua li no, qhov sib txawv ntawm analog thiab digital yog dab tsi?
Digital Cov teeb liab yuav tsum muaj qhov kawg ntawm cov txiaj ntsig tau. Tus naj npawb ntawm cov nqi hauv teeb tuaj yeem nyob qhov twg nruab nrab ob thiab ib-ntau-loj-ntau-uas-tsis-infinity. Qhov ntawd yog qhov loj Qhov sib txawv ntawm analog thiab digital nthwv dej. Analog nthwv dej yog du thiab nruam, digital nthwv dej yog stepping, square, thiab discrete.
Tsis tas li ntawd, qhov txawv ntawm analog thiab digital voltage yog dab tsi? Analog teeb liab yog nthwv dej tsis tu ncua uas hloov pauv mus rau lub sijhawm. Digital teeb liab yog discrete nyob rau hauv qhov. Qhov tseem ceeb Qhov sib txawv ntawm analog thiab digital teeb liab yog tias analog teeb liab yog sawv cev los ntawm sine waves whereas, lub digital teeb liab yog sawv cev los ntawm square waves.
Ua li no, piv txwv li analog thiab digital teeb liab yog dab tsi?
Muaj ib tug tsis tu ncua sawv cev ntawm teeb liab hauv analog signals . Muaj ib tug discontinuous sawv cev ntawm teeb liab hauv digital signals . Piv txwv ntawm analog signals yog Human Voice, Thermometer, Analog xov tooj thiab lwm yam. Piv txwv ntawm digital signals yog Computers, Digital Xov tooj, Digital pens lwm.
Cov piv txwv ntawm analogue yog dab tsi?
Piv txwv ntawm analogue systems suav nrog; Cov xov tooj cua qub, megaphones thiab tswj lub ntim ntawm cov xov tooj qub. Digital signals: Cov khoom siv hluav taws xob niaj hnub xws li khoos phis tawj thiab xov tooj ntawm tes nyob ntawm cov teeb liab digital.

Dab tsi yog qhov txawv ntawm ib qho digital thiab analog tov khoom?
Cov Mixers Digital tau nrawm nrawm tau piav qhia hauv cov ntsiab lus yooj yim tshaj plaws, qhov sib txawv ntawm analog thiab digital mixers yog tias lub suab teeb liab tau ua tiav hauv lawv daim ntawv analog lossis hloov mus rau thiab ua tiav daim ntawv indigital
Dab tsi yog qhov txawv ntawm qhov sib txawv hauv zos thiab thoob ntiaj teb hauv SQL Server?
Qhov sib txawv hauv zos tau tshaj tawm hauv ib qho kev ua haujlwm whereas Ntiaj teb hloov pauv tau tshaj tawm sab nraum lub luag haujlwm. Cov kev hloov hauv zos tau tsim thaum lub luag haujlwm tau pib ua tiav thiab ploj thaum lub luag haujlwm xaus, ntawm qhov tod tes, Ntiaj teb hloov pauv yog tsim raws li kev tua pib thiab ploj thaum qhov kev pab cuam xaus
Dab tsi yog qhov sib txawv ntawm lub thawv thiab lub thawv ntawv thiab lub thawv ntawv yog dab tsi?
Ib lub thawv thiab cov ntawv nplawm (qee zaum hu ua boxplot) yog ib daim duab uas nthuav tawm cov ntaub ntawv los ntawm tsib lub ntsiab lus. Nyob rau hauv ib lub thawv thiab whisker zajlus: qhov kawg ntawm lub thawv yog lub sab sauv thiab sab quartiles, yog li lub thawv spans lub interquartile ntau yam. qhov nruab nrab yog cim los ntawm ib txoj kab ntsug hauv lub thawv
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
Dab tsi yog qhov sib txawv ntawm qhov ntsuas qhov ntsuas thiab qhov ntsuas thib ob?
Primary index: nyob rau hauv ib tug sequentially order file, qhov Performance index uas nws search key qhia cov sequential order ntawm cov ntaub ntawv. Kuj hu ua clustering index. Secondary index: ib qho Performance index uas nws qhov tseem ceeb tshawb nrhiav qhia qhov kev txiav txim sib txawv ntawm qhov kev txiav txim ntawm cov ntaub ntawv. Kuj hu ua non-clustering index
