Question

We want to design logic circuits to convert the 4221 codewords of Problem P7.71 to BCD codewords. a. Fill in the Karnaugh map for A, placing x’s (don’t cares) in the squares for 4221 codes that do not occur in the table. Find the minimum SOP expression allowing the various x’s to be either 1s or 0s to make the expression as simple as possible. b. Repeat (a) for B. c. Repeat (a) for C. d. Repeat (a) for D.
