      X-OR gate has following truth table : It is represented by following logic relation Build this gate using AND, OR and NOT gates.
    A B Y
    0 0 0
    0 1 1
    1 0 1
    1 1 0
                   

    Answer:

                                      Given, the logic relation for the given truth table is                 Where  and    can be obtained as output of AND gate  for which one input is of A through NOT gate and another input is of B. y2 can be obtained as output of AND gate U for which one input is of A and other input is of B through NOT gate. Now y can be obtained as output from OR gate, where, y1 and y2 are input of OR gate. Thus the given truth table can be obtained from the logic circuit 9(EP).19.
