Design a circuit with inputs A, B,C, and D. Let the two inputs AB represent a two-bit number with A as the high order bit, and CD represent another two-bit number. That is, the values on AB represent four values 00 (0), 01 (1), 10 (2), and 11 (3). The circuit has three outputs: G, E, and L. Output G, E, and L should be 1 only if the number represented by AB is greater, equal, and less than the number represented by CD, respectively.
