Compute output of following logic gates as combinational circuit.
A+B
To determine the output of the given logic gate circuit, we need to analyze the components step-by-step.
- The first gate is an OR gate with inputs \(A\) and \(B\). The output of the OR gate is: \(A + B\)
- The output of the OR gate is then passed to a NOT gate (inverter). The NOT gate inverts its input, so the output of the NOT gate is: \(\overline{A + B}\)
- Following the NOT gate, the output \(\overline{A + B}\) is passed through another OR gate, which is configured as a NOR gate due to the inverter, giving us the double inversion: \(A + B\)
The final output of the combinational circuit is therefore \(A + B\).
Conclusion: The correct answer is A + B.
