Design a combinatorial circuit that generates 9's complement of a BCD number.[10]
The 9's complement of a BCD digit N is defined as: 9's complement = 9 - N Since BCD uses 4 bits to represent digits 0 through 9, we need a combinational circuit with 4 inputs (A, B, C, D) and 4 outputs (W, X, Y, Z). --- The BCD input represents digits 0-9. States 1010 to 1111 are invalid (don't c...
