Image text transcribed for accessibility: Use this comparator to design a circuit that takes two 4-bit inputs A and B and outputs A xor B if A < B, A' if A = B, (A' + B) if A > B. HINT: You may (and should) design a smaller circuit and use multiple copies of it in your overall desi (Note: these are bitwise computations; that is, [A xor B] should be interpreted as f3f2f1f0, where f_1 = a_i xor b_i, and similarly for the others.)
