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

Question

Aicharya · Accepted Answer

y 1 = A - , y 2 = B - y = y 1 + y 2 ¯ = A ¯ + B ¯ ¯ Using De-Morgan's theorem y = A ¯ + 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

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
