the output of the AND logic gate is F=A*B

in this tripple AND should be 0*C*D(bar) ?

whats the meaning of "0" ?

I need to take the logic integrand of a bigger combinative logic circuit and im stuck here.

 

With three inputs, F = A*B*C. Just satisfy the input conditions.

We know this because AND is commutative and associative.

If "0" means logic zero or false then the output can never be true. I'm guessing "0" means that something else is zero.

 

This thread is a duplicate of one I answered in the Projects forum early this afternoon:

Like Papabravo mentioned, I'd pointed out in the other thread that if the "0" input is indeed a logic low, the output will always be low/false no matter what the other inputs do.
