Question

How many two-input gates are needed for the logic circuit represented by X = C(A+B)?

A) One
B) Two
C) Three
D) Four

Answer 1

Three two-input gates are needed for the logic circuit represented by X = C(A+B).

Step-by-step explanation:

In the logic circuit represented by X = C(A+B), we have three inputs: A, B, and C. The logical operation being performed is an OR operation between A and B, and then ANDed with C. To perform this operation, we need two two-input gates: one for the OR operation and one for the AND operation. Therefore, the answer is C) Three.
