The logic operations of two combinational circuits in Figure-I and Figure -II are
Figure : 1
(x + y')' ===> [ (x + (x + y')']' ===> x'(x+y') ===>xx' + x'y' ===> x'y'
Figure : 2
(x+(x + y')')'=x'.(x+y')=x'y'
Ans.A entirely different
Although the answer is still same but a small confusion in the diagram ?
