Question
Which logic gate is represented by the following combination of logic gates ?
Options
A.NAND
B.AND
C.NOR
D.OR
Solution
y1 = 
, y2 = 
,
y =
(using De-morgan′s theorem)
y = A . B
Hence this logic gate represents AND gate.
Hence option (2)
, y2 = ,y =
(using De-morgan′s theorem)y = A . B
Hence this logic gate represents AND gate.
Hence option (2)
