Bits can be implemented in abounding forms. In best avant-garde accretion devices, a bit is usually represented by an electrical voltage or accepted pulse, or by the electrical accompaniment of a flip-flop circuit.
For accessories application absolute logic, a chiffre amount of 1 (or a analytic amount of true) is represented by a added absolute voltage about to the representation of 0. The specific voltages are altered for altered argumentation families and variations are acceptable to acquiesce for basic crumbling and babble immunity. For example, in TTL and accordant circuits, chiffre ethics 0 and 1 at the achievement of a accessory are represented by no college than 0.4 volts and no lower than 2.6 volts, respectively; while TTL inputs are defined to admit 0.8 volts or beneath as 0 and 2.2 volts or aloft as 1.
