Design a circuit that decrements a four bit binary number. Assume that decrementing 00002 (010) should give the output 11112 (1510). Use Karnaugh maps for simplification.

Show: (i) the truth table(s)

(ii) Karnaugh maps (K maps) for each output function

(iii) simplified formulas for each function derived from the K maps

Please see that the circuit is decrements and NOT increments.
