ternary selector gate

views updated

ternary selector gate (T-gate) A combinational ternary logic gate that is important as a building block in the synthesis of ternary logic circuits (see multivalued logic). A T-gate has four inputs {a0, a1, a2, s}

and one output {t}, all of which can take values represented by elements of the set {0,1,2}. The function of the T-gate is given by t = as. It thus acts as a ternary selector, the choice from {a0, a1, a2}

being selected by the value taken by the s input.
