Answer the following questions:
1. Design a digital combinational circuit which compares two 2-bit binary numbers and produces results using a 2-bit binary number (please see the block diagram below). The output Z1Z0 depends on the inputs A1A0 and B1B0 according to the following criteria:
• If (A1A0 B1B0) the output Z1Z0 = 10
• If (A1A0 B1B0) the output Z1Z0 = 01
• If (A1A0 = B1B0) the output Z1Z0 = 11
