Question

To compare the two binary numbers, first the most significant bits (MSBs) are compared. If the MSBs are equal, then the next significant bits are compared. However, if the MSBs are not equal, then either A is greater than or less than B hence further comparison is not needed. For example, when comparing two 2-bit numbers given by A A1A2 and B-B,B2. If Al B1, then A > B if A1 = 1, B1 = 0 or A < B if A.-0, B1 = 1. If the MSBs are equal, then the next significant bits Ao and Bo are compared to decide whether A B. The comparator overall generates three outputs, L, E and G, corresponding to whether A < B, A = B, A> B. Design a comparator that compares two 4-bit binary numbers. Use multiple 4-bit comparators to design a system that compares three 4-bit binary numbers considering what the possible outputs of a three number comparator would be.
