The output of an OR gate is connected to both the inputs of a NAND gate. The combination will serve as a

A

NOT gate

B

NOR gate

C

AND gate

D

OR gate

Text Solution

Verified by Experts

The correct Answer is:
B
`(bar(A + B))`= NOR gate
When both inputs of NAND gate are connected, it behaves as NOT gate
`OR + NOT = NOR`
