Question

State the principle of duality gibe the dual of the boolean relations
1 A+(A'B) =A+B. 2 A+0=A

Answer 1

Answer:

The principle of duality states that starting with a Boolean relation, another Boolean relation can be derived by :

1. Changing each OR sign(+) to an AND sign(.).
2. Changing each AND sign(.) to an OR sign(+).
3. Replacing each 0 by 1 and each 1 by 0.
4. The dual of (X + Y).(X’ +Z’).(Y + Z) is XY.
