$OR$ gate

Vedclass · Answer

(D) Using the distributive law of Boolean algebra,the expression can be simplified as follows:$P + \overline{P}Q = (P + \overline{P}) \cdot (P + Q)$Since $(P + \overline{P}) = 1$,the expression becomes:$1 \cdot (P + Q) = P + Q$The expression $P + Q$ represents the output of an $OR$ gate.Alternatively,we can construct the truth table:$P$$Q$$\overline{P}$$\overline{P}Q$$P + \overline{P}Q$$0$$0$$1$$0$$0$$1$$0$$0$$0$$1$$0$$1$$1$$1$$1$$1$$1$$0$$0$$1$The output column for $P + \overline{P}Q$ matches the truth table of an $OR$ gate. Thus,the correct option is $D$.

The Boolean expression $P + \overline{P}Q$,where $P$ and $Q$ are the inputs of the logic circuit,represents
