You might be used to drawing truth tables for the gates but in complex systems this becomes very ungainly so we’ll use the Boolean logic representation here. By far, the most common digital integrated circuits built today use CMOS logic, which is fast, offers high circuit density and low-power per gate. Logic redundancy can be removed by several well-known techniques, such as binary decision diagrams, Boolean algebra, Karnaugh maps, the Quine–McCluskey algorithm, and the heuristic computer method.
