“A 1-bit full adder with inputs A, B and Cin: two XOR gates for Sum, and two AND gates into an OR gate for Cout.”
그렇다면Chain four of them into a 4-bit ripple-carry adderRebuild it using only NAND gates
1-bit full adder built from XOR, AND, and OR gates — the foundational building block of every arithmetic logic unit, from a functional description.
