Question

Design a combinational circuit that converts a four-bit Gray code into a 4-bit Binary number. Implement this circuit using XOR gates only. As an example, see below the Gray code vs. decimal equivalent in Table Gray code Decimal Equivalent Gray Code Decimal Equivalent 0000 0 1100 8 0001 1 1101 9 0011 2 1111 10 0010 3 1110 11 0111 4 1010 12 0101 5 1011 13 0110 6 1001 14 0100 7 1000 15 Discuss a 2-to-4-decoder implementation including a truth table and present its logic diagram and equations using NOR gates only. Include an enable (E) input.
