The 9's complement of a decimal digit d (0 to 9) is defined to be 9 - d. A logic circuit produces the 9's complement of an input digit where the input and output digits are represented in BCD. Label the inputs A, B, C, and D, and label the outputs W, X, Y and Z. (a) Determine the minterms and don't-care minterms for each of the outputs. (b) Determine the maxterms and don't-care maxterms for each of the outputs. The 9's complement of a decimal digit d (0 to 9) is defined to be 9 - d.
