Question

Which logic gate is represented by the following combination of logic gates?

  1. OR    
  2. NOR    
  3. AND    
  4. NAND    

The correct answer is: AND


    Output of gate-1,

    Output of gate-2,
    Output of gate 3 Y subscript 1 end subscript equals stack A with minus on top
    Y subscript 2 end subscript equals stack B with minus on top
    Y equals stack Y subscript 1 end subscript plus Y subscript 2 end subscript with minus on top equals stack stack A with minus on top plus stack B with minus on top with minus on top equals stack A B with ̿ on top equals A B
    which is the output of AND gate.
