22.
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).
