digital logic
digital logic A methodology for dealing with expressions and
state tables containing discrete (usually two-state) variables: in this sense the term is synonymous with
Boolean algebra (see also
multivalued logic). The term is also applied to the hardware – components and circuits – in which such expressions and tables are implemented. See also
digital design,
logic circuit,
combinational circuit,
sequential circuit,
q-ary logic.
