The logic performed by the circuit shown in figure is equivalent to

The logic performed by the circuit shown in figure is equivalent to

The logic performed by the circuit shown in figure is equivalent to

Options

AAND
BNOR
COR
DNAND

Correct answer

A. AND

Step-by-step solution

All the gates used in the given configuration are $NOR$ gates. Thus, the output can be found as follows-

$\begin{cases}Y & = & \left(a + b\right) \\ & = & \left(ab\right) \\ & = & ab\end{cases}$

The output of the given configuration can also be verified by the following truth table:

$a$	$b$	$Outputfromfirstgate$	$Outputfromsecondgate$	$Y$
$0$	$0$	$1$	$1$	$0$
$0$	$1$	$1$	$0$	$0$
$1$	$0$	$0$	$1$	$0$
$1$	$1$	$0$	$0$	$1$

The calculation and the truth table clearly shows that the configuration represents $AND$ gate.
