Combination of NAND gates is shown in the figure. It is equivalent to which gate:

Options

  1. ANOR gate
  2. BAND gate
  3. COR gate
  4. DX-OR gate

Correct answer

C. OR gate

Step-by-step solution

The two NAND gates whose two inputs are joined together behave like NOT gates. The truth table can be written as We see that the output y is ' 1 ' if A or B or both are ' 1 '. Hence it behaves as OR gate.
