A jet has 4 engines, A and B on the left wing, C and D on the right wing. Each engine gives a FAIL signal which is TRUE if the engine is broken, and is FALSE if the engine is working fine. The plane can fly as long as at most 1 engine on each wing is broken. We want a signal EMERGENCY, which is true if the plane can no longer fly.
a.) Would the Sum of Minterms or Product of Maxterms be smaller for this circuit?
b.) Write the Boolean equation for EMERGENCY. It should be in the format identified in 4a above (Sum of Minterms or Product of Maxterms, whichever is smaller)
