Question

How many AND gates are required to realize \( Y = CD + EF + G \)?

• A. 4
• B. 5
• C. 3
• D. 2

Hint:

When designing logic circuits, count the number of AND operations required based on the number of terms being multiplied.

Answer 1

The Correct Option is D

To realize the Boolean expression \( Y = CD + EF + G \), two AND gates are required: one for \( CD \), one for \( EF \), and the final OR gate for combining the results with \( G \). Therefore, the correct answer is option (4).
