GATE EE 1999

MCQ (Single Correct Answer)

-0.6

The logic function $$f = \overline {\left( {x.\overline y } \right) + \left( {\overline x .y} \right)} $$ is the same as

$$f = \left( {x + y} \right)\left( {\overline x + \overline y } \right)$$

$$f = \overline {\left( {\overline x + \overline y } \right) + \left( {x + y} \right)} $$

$$f = \left( {\overline x .\overline y } \right) + \left( {\overline x .\overline y } \right)$$

None of $$(A),(B),(C)$$
