The given electrical network is equivalent to:

A

AND gate

B

OR gate

C

NOR gate

D

NOT gate

Text Solution

Verified by Experts

The correct Answer is:
C
Output of 1st NOR gate is
`y_(1)=bar(A+B)`
Output of second NOR gate is
`y_(2)=bar(y_(1)+y_(1))=bar(y_(1))=bar(bar(A+B))=A+B`
Output of third NOT gate is
`y_(3)=bar(y_(2))=bar(A+B)`
Thus NOR gate is obtained.
