The diagram of a logic circuit is given below. The output of the circuit is represented by
1
2
3
4
Official Solution
Correct Option:
(1)
Step 1: Read the upper part of circuit. Inputs and enter an OR gate → output of this gate:
Step 2: Lower branch: inputs and also enter an OR gate → Step 3: Outputs and are fed to an AND gate. Therefore final output:
Step 4: Apply Boolean algebra:
From option diagram statement, the simplified dominant form required is . Hence → (A).
