Analog vs Digital Circuits
Analog circuits thiab digital circuits yog ib txoj hauv kev faib cov hluav taws xob hluav taws xob. Lub tswv yim ntawm analog piv rau digital yog ib lub tswv yim tseem ceeb uas tau tham txog hauv physics, engineering, electronics, xam, instrumentation, lej thiab ntau yam hauj lwm. Hauv tsab xov xwm no, peb yuav tham txog dab tsi analog circuits thiab digital circuits yog, thiab qhov txawv ntawm analog circuits thiab digital circuits.
Analog Circuits
Feem ntau ntawm cov chaw uas peb ntsib hauv peb lub neej niaj hnub yog cov koom haum analog. Analogue Circuit Court yog ib lub voj voog uas tswj los yog ua haujlwm ntawm cov ntaub ntawv analog. Nyob rau hauv physics, raws li zoo raws li electronics, analog yog ib lo lus uas siv los piav txog ib tug teeb liab los yog ib tug muaj nuj nqi uas yuav coj ib tug nqi ntawm ib cheeb tsam. Lub teeb liab analog yog txuas ntxiv. Lub teeb liab sinusoidal voltage yog ib qho piv txwv zoo heev rau cov teeb liab analog. Ib qho analog teeb liab muaj ntau qhov tseem ceeb ntawm ob qho txiaj ntsig. Qhov no, txawm li cas los xij, txwv los ntawm kev muaj peev xwm thiab kev daws teeb meem ntawm cov cuab yeej siv los ntsuas cov teeb liab no.
Cov cim qhia analog tuaj yeem kuaj pom thiab tshuaj xyuas siv cov cuab yeej xws li cathode ray oscilloscopes, voltmeters, ammeters thiab lwm yam khoom siv kaw. Yog hais tias lub teeb liab analog yuav tsum tau soj ntsuam siv lub computer, nws yuav tsum tau hloov mus rau hauv cov teeb liab digital. Qhov no yog vim cov khoos phis tawj tsuas muaj peev xwm tuav cov teeb liab digital. Analog suav tuaj yeem ua tiav siv cov khoom siv xws li kev ua haujlwm amplifiers thiab transistors.
Digital Circuits
Lo lus "digital" yog los ntawm lo lus "digit" uas txhais tau hais tias tus lej tshwj xeeb. Lub voj voog digital yog ib lub voj voog uas ua haujlwm thiab ua haujlwm ntawm cov ntaub ntawv digital. Txawm hais tias lub voj voog digital ua haujlwm ntawm cov ntaub ntawv digital, cov khoom siv raws li cov khoom siv hluav taws xob analog. Lub teeb liab digital tuaj yeem siv cov txiaj ntsig tsis sib xws. Piv txwv li, qib logic ntawm 1 thiab 0 yog cov txiaj ntsig digital. Lub logic theem ntawm 1 thiab 0 los yog "tseeb" thiab "false" tsis muaj nyob. Yog hais tias lub teeb liab digital yog digitized nrog qhov tseem ceeb ze rau ib leeg thiab nrog ntau tus nqi, nws tuaj yeem hais tias lub teeb liab yog qhov kwv yees zoo rau cov teeb liab sib xws.
Computers siv cov teeb liab digital hauv lawv cov circuits sab hauv tab sis feem ntau ntawm lwm cov khoom siv siv cov cim analog. Qhov tsawg kawg daws teeb meem digital muaj ob qhov txiaj ntsig tsis sib xws. Qhov hluav taws xob tiag tiag ntawm cov no nyob ntawm lub cev siv hluav taws xob. Ob theem teeb liab no hu ua binary signals. Lub teeb liab decimal muaj 10 voltage theem, thiab lub teeb liab hexadecimal muaj 16 qib voltage. Lub analog circuit lub luag hauj lwm rau tuav cov ntaub ntawv digital yog tsim kom muaj ntau tshaj qhov tseeb digital tus nqi raug kuaj pom raws li tus nqi analog nws tus kheej. Qhov no yog vim qhov yuam kev ntawm lub teeb liab thiab deformation los ntawm cov khoom.
Qhov txawv ntawm Digital Circuit thiab Analog Circuit Court yog dab tsi?
• Analog circuits ua haujlwm ntawm cov ntaub ntawv analog whereas digital circuits ua haujlwm ntawm cov ntaub ntawv digital.
• Analog circuits feem ntau muaj kev daws teeb meem ntau dua li digital circuits.
