Ib qho tsis thiab lub inverter yog ob qho tib si tseem ceeb hauv cov khoom siv hluav taws xob digital. Qhov sib txawv tseem ceeb ntawm ob qho no yog txoj hauv kev uas lawv tswj cov teeb liab tawm tswv yim.
Ib qho tsis yog ib qho cuab yeej uas ua kom pom cov teeb liab tawm tswv yim thiab tswj nws qib qub. Nws muaj lub siab input impedance thiab qis tso zis impedance, ua rau nws muaj txiaj ntsig hauv kev xa cov cim tsis muaj degrading lossis distorting lawv. Buffers feem ntau yog siv nyob rau hauv circuits qhov twg lub input teeb liab yuav tsum tau dhau los ntawm ntau yam khoom siv tsis tau poob nws thawj lub teeb liab zog.
Ntawm qhov tod tes, ib qho inverter yog ib qho khoom siv uas hloov cov txiaj ntsig ntawm cov teeb liab tawm tswv yim. Nws hloov lub teeb liab "siab" lossis "qis" mus rau theem rov qab. Yog li, lub logic '1' dhau los ua '0' thiab vice versa. Inverters feem ntau yog siv nyob rau hauv digital circuits los ua ntau yam haujlwm xws li moos teeb liab shaping, teeb liab inversion, thiab logic ua haujlwm.
Lwm qhov sib txawv ntawm ib qho tsis thiab lub inverter yog lawv cov teeb liab tso zis. Lub teeb liab tso zis ntawm ib qho tsis yog zoo ib yam rau lub teeb liab input, tab sis cov teeb liab tso zis ntawm lub inverter yog qhov cuam tshuam ntawm lub teeb liab input.
