5. Design a combinational circuit with three inputs A, B, C and three outputs x, y, x. The output is one less than the input if the binary input is 1, 2, or 3. The output is one greater than the input if the binary input is 4,5,6. The output is equal to the input if the binary input is or 7. Implement with two-level NOR technology. a. Block diagram b. Truth table c. K-maps and simplified POS d. Logic diagram with NOR-NOR implementation
