Hey,

I want to convert the following expression to NAND2 form, so all terms are in the NAND form

Z'W+Z'XY+WY'
= W(Z'+Y')+Z'XY

A partial solution:

w (z'+y')+z'xy

= (w (z'+y')+z'xy)''

= (w' + (z'+y')' (z'xy)')'

= w' + (z''y'') (z''+x'+y')

= w' + (zy) (z+x'+y')


Is that right so far?

Is the next step the use of two bars over the (zy)(z+x'+y') terms?

Thanks.

Hi,

If you have a logic template, try working it out as signals applied to NAND gates. Not very elegant, but you can at least see how it works. MIL-STD 806C forever!

They're easy to draw freehand, too.
