I read online that if we have a set of SOP terms giving a boolean expression, then the POS terms of the complement of the SOP terms will give the same expression. POS(f)=SOP(f').
This is called taking the dual of the expression. How does this work?
If I have: f = BD + AC + CE
Its complement: f' = (B' + D')(A' + C')(C' + E')
What is meant by taking the dual of f, and how do we get f in POS form?
