Question

Show how can you make an OR logic using AND and NOT logic gates.

Answer 1

(x+y)=`(`x*`y)

Step-by-step explanation:

We have to apply some properties of logic gates (as involution and DeMorgan's law) in order to get the answer:

``(`x)=x\\and\\`(x+y)=`x*`y`

applying the last two properties:

`(x+y)=`(`(x+y))\\(x+y)=`(`x*`y)`

So if we negate x and y, multiply them and then negate them again, it will be equal to a logic sum.
