Find 'X' in the circuit below :
f1(A, B, C, D) = Σ(6, 7, 13, 14);
f2(A, B, C, D) = Σ(3, 6, 7);
f3(A, B, C, D) = Σ(5, 6, 7, 14, 15)
f1(A, B, C, D) = Σ(6, 7, 13, 14);
f2(A, B, C, D) = Σ(3, 6, 7);
f3(A, B, C, D) = Σ(5, 6, 7, 14, 15)
Answer: Option
Explanation:
f1(A, B, C, D) = ∑(6, 7, 13, 14)
f2(A, B, C, D) = ∑(3, 6, 7)
f1 ⊕ f2 = ∑(3, 13, 14)
f3 x (f1 ⊕ f2) = ∑(14) = y
X = f1 x y ⇒ ∑14.

I also think that the answer is '0'.

Cam someone explain it clearly?

Here,
X = (f1 + y')' = 0.
X = (f1 + y')' = 0.
