ANORBANDCORDNAND

Show answer and solution▾

Answer: (B) AND

As shown in the figure the various logic gates have been mentioned.
Let the output before the $NOT$ gate be $Z$.
Using the expression for the logic gates, it can be written
$Z=\left(A+B\right)\cdot (A\cdot B)$
Hence, the output $Y$ is
$Y=Z=\left(A+B\right)\cdot (A\cdot B) \Rightarrow Y=A\cdot B$
Hence the digital circuit is equivalent to an $AND$ gate.
