how do i implement nand using pos

Hi
I think its clear when you expand SOP and POS

SOP - Sum Of Products
POS - Product Of Sums

using nor to implement sop

Yes it has another reason:
it is because, we use NAND/NAND, insted using AND/OR.
in other word, we use one type of logic.
this is because we use demorgan law.
if you check circuit diagram , you will find them.

Davood.
