In the following circuit, the output `Y` for all possible inputs `A` and `B` is expressed by the truth table:

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
Gates-I and II are NOR gates. We can simplify the gate circuit as

The final output is
`Y=barbar(A+B)=A+B`
This is the Boolean expreesion of OR gate whose truth table is given below
