In digital circuits, a logic level is one of a finite number of states that a digital signal can inhabit. Logic levels are usually represented by the voltage difference between the signal and ground, although other standards exist. The range of voltage levels that represent each state depends on the logic family being used.A logic-level shifter can be used to allow compatibility between different circuits.

rdfs:comment	Logická úroveň je reprezentace logické hodnoty v číslicové technice určitým stavem elektrického obvodu, nejčastěji úrovní elektrického napětí vůči společnému vodiči. Mimo elektroniku mohou pro reprezentaci logické úrovně sloužit i jiné fyzikální veličiny (tlak v pneumatických systémech, intenzita světla v optoelektronice). Digitální signál (binární) V naprosté většině případů rozlišujeme dvě úrovně, Vysokou úroveň (H-level a High, H) a Nízkou úroveň (L-level, Low, L). (cs) Logikpegel bezeichnen in der Digitaltechnik die meist zur Repräsentation der Logikwerte verwendeten elektrischen Spannungen. Es kann sich aber auch um andere physikalische Größen handeln (Druckpegel in der Pneumatik, Lichtstrom bei der Optoelektronik). Bei digitalen, üblicherweise binär codierten Signalen sind zwei Spannungsbereiche erlaubt, die High-Pegel (auch H-Pegel, High, H) bzw. Low-Pegel (L-Pegel, Low, L) genannt werden.
