Solutions to Exercises in Digital Electronic Systems Unit 6
Solution – (Ex. 1)
The terms to which De Morgan’s theorems are applied are identified.
Assign
Then
Solution – (Ex. 2)
Solution – (Ex. 3)
The terms to which De Morgan’s theorems are applied are identified.
Assign
Recalling that
This yields
Now De Morgan’s Theorem is applied to the second term, as the first term cannot be minimised any further.
Assign
Recalling that

Solutions to Exercises in Digital Electronic Systems Unit 6
This yields
The overall function is
This can be rewritten in Sum of Products (SOP) form by applying the distribution rule
Solution – (Ex. 4)
As before we select the X and Y terms for application of De Morgan’s Theorem.
Recalling that
Thus
Now we apply De Morgan’s theorem to each of the terms in the brackets
This is the function expressed in Sum of Products (SOP) form.
Solution – (Ex. 5)
2
Note where line is split
