Which of the following block circuit diagram is correct for F?
(A) Only 1
(B) Only 2
(C) Both 1 and 2
(D) None of these
Answer: (C)
Explanation: To draw the circuit diagram, we must know the Boolean function. We can find the Boolean function with the help of Knaurgh-map. From the given truth table it is depicted that F(A, B, C) = Σ(2, 3, 5, 6, 7).
Therefore, both given logic circuit structures are equivalent to given function F = B + AC.
So, option (C) is correct.
