Which logic gate is represented by the following combination of logic gates?

NEET 2015 (Phase 1)

Options:

Answer:

Solution:

$y_{1} = \bar{A}, y_{2} = \bar{B}$

$y = \bar{y_{1} + y_{2}} = \bar{\bar{A} + \bar{B}}$

Using De-Morgan's theorem

$y = \bar{\bar{A} + \bar{B}} = A . B$
So, it is AND gate
Truth table:

A	B	$y_{1}$	$y_{2}$	y
0	0	1	1	0
0	1	1	0	0
1	0	0	1	0
1	1	0	0	1
