Logic Gates

Identify the correct Logic Gate for the following output (Y) of two inputs A and B.

Show answer and solution

Answer: (b)

Read the waveform: $Y = 0$ only in the intervals where $A = 1$ and $B = 1$ .
For $(0,0), (0,1), (1,0)$ the output is 1, so $Y = \overline{AB}$ (NAND).
Option (b) is an AND gate followed by NOT, i.e. NAND.
So the answer is (b).
