Example convert to NAND?

Hey,

We had a networking test yesterday, and this example came up. No one in the class knows how to solve it. The task is to convert this example to NAND (not AND). I need an explanation, please. The teacher is too lazy to explain it to us and just gave us a hint that we should use Morgan's Law.

thank you in advance

You can find this here:

Under laws, other notation, is virtually your example, just a little shorter.

This is already a NAND equation.

You have an AND gate with 7 inputs, with input B and C negated. The solid cross-section above the equation tends the whole again, i.e. the output of your AND gate is now also negated while the inputs remain as above.

Probably you should make a NOR or OR out of it. To do this, you always “cut” the long bar where the AND link sign stands (^ ), thus each variable gets its own cross-slot. If one was present before (as with B and C), they are additionally retained.

By the “snowing” you also converge the links, because from And (^ ) becomes an Or (v ).
