Solution

The correct option is D XOR
In the given truth table, output is 1 when exactly one of the inputs is 1 and the other is 0. Output is 0 if both inputs are same (0 or 1). This is the characteristic of XOR gate.
$Y = A ¯ ¯¯ ¯ B + ¯ ¯¯ ¯ A B$

Q. Write the truth table for circuit given in Fig. 14.47 below consistingof NOR gates and identify the logic operation (OR, AND, NOT) whichthis circuit is performing.(Hint: A = 0, B = 1 then A and B inputs of second NOR gate will be 0and hence Y=1. Similarly work out the values of Y for othercombinations of A and B. Compare with the truth table of OR, AND,NOT gates and find the correct one.)
