Question

A logic gate circuit has two inputs $A$ and $B$ and output $Y$. The voltage waveforms of $A,B$ and $Y$ are shown below.


The logic gate circuit is :

Answer 1

From waveforms, if we draw the truth table we have

A	B	Y
0	0	0
1	1	1
0	1	0
1	0	0

So, it is AND gate
Hence, option $\left(A\right)$ is correct.
