An Incompletely specified function is a Boolean function that only define output values for a subset of its inputs. Incompletely specified functions often make no guarantees as to the unspecified output whatsoever.
Overview
In many situations when working with combinational circuits, some combinations of inputs should not occur under normal working conditions. For those combinations the output can be disregarded allowing for possibly further logic minimization.
