The circuit given below represents which of the logic operations?

A

`AND`

B

`NOT`

C

`OR`

D

`NOR`

Text Solution

Verified by Experts

The correct Answer is:
a
Let two inputs are `A` and `B`. The circuit can be shown as:

The two gates shown are `NAND` gates.
The output of gate `,1,Y_(1)=bar(A.B)`
The output gate `2, Y=bar(Y_(1).Y_(1))`
or ` Y=bar(bar(A.B).bar(A.B))`
`=bar(bar(A.B)`
`A.B`
Thus, the combination behaves as it is an `AND` gate.
