Mcq 5 answer is S=1, Cout=1 Sum (S) = A ⊕ B ⊕ Cin = 1 ⊕ 1 ⊕ 0 = 1 (where ⊕ denotes the XOR operation) Carry out (Cout) = (A ⋅ B) + (Cin ⋅ (A ⊕ B)) = (1 ⋅ 1) + (0 ⋅ (1 ⊕ 1)) = 1 + 0 = 1 (where ⋅ denotes the AND operation) So, the output sum (S) is 1 and the carry out (Cout) is also 1.
Mcq 4 answer is function
Mcq 5 answer is S=1, Cout=1
Sum (S) = A ⊕ B ⊕ Cin = 1 ⊕ 1 ⊕ 0 = 1 (where ⊕ denotes the XOR operation)
Carry out (Cout) = (A ⋅ B) + (Cin ⋅ (A ⊕ B)) = (1 ⋅ 1) + (0 ⋅ (1 ⊕ 1)) = 1 + 0 = 1 (where ⋅ denotes the AND operation)
So, the output sum (S) is 1 and the carry out (Cout) is also 1.
