Muaj ntau txoj hauv kev los faib cov kev sib xyaw. Raws li seb lub Circuit Court puas zoo ib yam li digital lossis digital, nws muaj peev xwm muab faib ua: cov hluav taws xob sib txuas ua ke, digital txuas Circuit Court thiab teeb liab sib xyaw ua ke (Circuit Court thiab digital ntawm ib qho nti).
Kab hluav taws xob sib xyaw ua ke tuaj yeem muaj txhua yam, txij txhiab mus txog ntau lab qhov rooj laj kab, flip-flops, multiplexers thiab lwm cov kab hluav taws xob hauv ob peb square millimeters. Qhov ntsuas me me ntawm cov kev ua haujlwm no ua rau muaj kev kub ceev dua, kev siv hluav taws xob tsawg (saib Cov Qauv Hluav Taws Xob Qes) thiab kev tsim khoom qis dua piv rau pawg tswj hwm qib. Cov ICs digital, sawv cev los ntawm microprocessors, digital signal processors thiab microcontrollers, siv cov kab ke binary hauv lawv cov haujlwm los ua cov txheej txheem 1 thiab 0 teeb liab.
Analog sib xyaw ua ke muaj xws li cov ntsuas pa, tswj hluav taws xob, thiab ua haujlwm kom muaj suab nrov, uas ua cov cim kev sib txuas. Ua tiav cov haujlwm ntawm kev ua kom nrov dua, lim av, tsim tawm, thiab muaj kev sib xyaw. Los ntawm kev siv cov ntawv tso hluav taws xob txuas ntxiv tsim los ntawm cov kws tshaj lij nrog cov yam ntxwv zoo, lub nra ntawm cov tsim hluav taws xob raug txo qis, thiab txhua yam tsis tas yuav tsum tau tsim los ntawm cov pib transistors.
Cov kab ke sib xyaw ua ke tuaj yeem sib txuas ntawm cov hluav taws xob analog thiab digital rau ntawm ib qho nti los ua cov cuab yeej xws li cov hloov digital-to-digital thiab cov hloov digital-rau-analog. Qhov Circuit Court no muaj cov qauv me me thiab tus nqi qis dua, tab sis yuav tsum tau ceev faj txog teeb meem tsis sib haum.
