Blake canonical form Blake canonical form In Boolean logic, a formula for a Boolean function "f" is in Blake canonical form (BCF), also called the complete sum of prime implicants, the complete sum, or the disjunctive prime form, when it is a disjunction of all the prime implicants of "f". The Blake canonical form is a disjunctive normal form. The Blake canonical form is not necessarily minimal, however all the terms of a minimal sum are contained in the Blake canonical form. It was introduced in 1937 by Archie Blake, who called it the "simplified canonical form"; it was named in honor of
