(a) Use logic simulation to verify that the circuits described in implement the BCD–to–seven-segment converter correctly.

(b) Design the converter assuming that the unused input combinations (minterms 10–15) can be don’t cares rather than 0s. Simulate your design and compare it to your simulation from part (a).
