Tardigrade Admin · Accepted Answer

The boolean expression of this arrangement is, For NOT gate, Y1= barA and Y2= barB For NOR gate, Y= bar barA + barB = bar barA⋅ bar barB Y=A⋅ B Truth Table 0 Thus, the combination represents AND gate.

Q. Consider the circuit of logic gates shown in the above figure. This combination of logic gates can be replaced by which logic gate?

OR

NAND

AND

NOR

The boolean expression of this arrangement is, For NOT gate, Y1​=Aˉ and Y2​=Bˉ For NOR gate, Y=Aˉ+Bˉˉ​ =Aˉˉ⋅Bˉˉ Y=A⋅B Truth Table 0 Thus, the combination represents AND gate.
