(i) Identify the logic gates marked P and Q in the given logic circuit Fig. (ii) Write down the output at X for the inputs `A=0, B=0` and `A=1, B=1`.

Answer» Logic gate P is NOT gate and logic gate Q is OR gate.
The Boolean expression for this gate is
`X=barA+B`
The truth table for the given values of A and B of the above circuit is shown below.
`|{:(A,barA,B,y=barA+B),(0,1,0,1),(1,0,1,1):}|`
