And-Or-Invert Gates

Common forms of two-level logic gates are and-or-invert (AOI) and or-and-invert (OAI) gates.

and-or-invert sum of products AOI-21 = [AB+C]' 2+1 = 3 inputs

AOI-231 = [AB+CDE+F]' 2+3+1 = 6 inputs

or-and-invert product of sums OAI-21 = [(A+B)(C)]' 2+1 = 3 inputs

OAI-231 = [(A+B)(C+D+E)(F)]' 2+3+1 = 6 inputs

and-or-invert	sum of products	AOI-21 = [AB+C]'	2+1 = 3 inputs
		AOI-231 = [AB+CDE+F]'	2+3+1 = 6 inputs
or-and-invert	product of sums	OAI-21 = [(A+B)(C)]'	2+1 = 3 inputs
		OAI-231 = [(A+B)(C+D+E)(F)]'	2+3+1 = 6 inputs
