Hi all,

If we are implementing the SOP and POS form of the same function using NAND gates,will they give the same result?

Or will the result be complement to each other?

whats the role of implementing using NOR here?

hello vivek.
The duality principle is a simple equivalence relation.
If you have a set of SOP terms giving a boolean expression, if you take the POS terms of the complement of the SOP terms you'll get the same expression.
POS(f)=SOP(f`)
NAND gives you SOP. with NOR its easy to implement POS.
Hope this helps.

Satan helps those that do their own homework.

Same for Jesus, Buddha and Thor. It's mostly a placeholder for "you" really. So what fine attempts have you done so far for this assignment and where are you stuck?
