Computer Science for IGCSE & O level - Boolean Logic (Section 1 - No. 12)
Which of the following logic circuits represents the given Boolean expression: Y = A OR (B AND C)?
A circuit with an AND gate, whose inputs are B and C. And the output of this gate is fed in an OR gate along with A.
A circuit with an OR gate, whose inputs are A and B and the output of this gate is fed in an AND gate along with C.
A circuit with an OR gate, whose inputs are A and C and the output of this gate is fed in an AND gate along with B.
A circuit with an AND gate, whose inputs are A and B, and the output of this gate is fed in an OR gate along with C.
Explanation
The correct circuit structure aligns with the order of operations dictated by the expression: B and C are AND'd first, and then the result is OR'd with A.
