Q: One general doubt I m having is that can combinational circuit namely multiplexer, demultiplexer and decoder be implemented in POS ( Product of Sum) form??

If so what modification is required ?

is there any difference in represent one circuit in SOP and in POS form?

I think no.

Actually we are habituated in writing an expressin in SOP form. Same can berepresented in POS too

@Habib, I think we can do this.

1) Multiplexer

Multiplexers are universal circuit. So it can be definitely implemented in POS.

2) Demux and Decoder

In order to get POS form, connect the output to NOR gate and u will get POS form. I have assumed that the docoder is positive logic one. For negative logic decoder use AND gate.

Consider a $3-bit$ number $A$ and $2 bit$ number $B$ are given to a multiplier. The output of multiplier is realized using $AND$ gate and one-bit full adders. If the minimum number of $AND$ gates required are $X$ and one-bit full adders required are Y, then $X+Y = $ _______
