8. The dual of the switching function x + yz is:1) yzx 2) zyx 3) zyx 4) z
Question
- The dual of the switching function x + yz is:1) yzx 2) zyx 3) zyx 4) z
Solution
The dual of a switching function is obtained by swapping '+' with '.' and vice versa, and swapping '0' with '1' and vice versa.
The switching function given is x + yz.
To find its dual, we swap '+' with '.' and vice versa.
So, the dual of the switching function x + yz is x . (y + z).
Therefore, the answer is (y + z) . x, which corresponds to option 3) zyx .
