Identify the logic gate given in the circuit :
  1. (A)NAND - gate
  2. (B)OR - gate✓ Correct
  3. (C)AND gate
  4. (D)NOR gate

Answer: (B)

Solution

Each input and first passes through a NOT gate, and the two outputs feed a NAND gate, so

By De Morgan's theorem, .
So , which is the OR operation.
