Output of following logic circuit is

Step-by-step solution

In the given circuit, the outputs of all three O R gates is given to the input of A N D gate. Inputs to the first O R gate are A ¯ and B as a N O T gate in between the input from A . Similarly, inputs to second O R gate are A ¯ and C ¯ . And to third O R , inputs are B and C ¯ . We know the output of an O R gate is the sum of inputs. Then, the outputs of the three O R gates are A ¯ + B , A ¯ + C ¯ and B + C ¯ . Now, we know that the output of the A N D gate is the multiplicat
