Question

Identify the gates P and Q shown in figure. Write the truth table for the combination of the gates shown.
Name of equivalent gate representing this circuit and write its logic symbol

Answer 1

Here the gate $P$ is $AND$ gate and gate $Q$ is $NOT$ gate. The truth table for the combination of the gates is as shown in the figure.

The equivalent gate will be a $NAND$ gate and its truth is shown in the figure.
