Give the dual form of: 1. 0.X + X.Y + 1.X 2. X.(Y+Z) = X.Y + X.Z

Question

Give the dual form of:

1. 0.X + X.Y + 1.X

2. X.(Y+Z) = X.Y + X.Z

3. X + X’.Y = X + Y

4. 1 + X = 1

Answer 1

The dual form of

1. 0.X + X.Y + 1.X is 1 + X’. X’ + Y’. 0 + X’
2. X.(Y+Z) = X.Y + X.Z is X’ + (Y’.Z’) = X’ + Y’. X’ + Z’
3. X + X’.Y = X + Y is X’. X + Y’ = X’. Y’
4. 1 + X = 1 is 0.X = X.
