Any logic gate that gives this result?

[fractal]

T T -> T
T F -> T
F T -> F
F F -> T

Obviously the usual (NOR, XOR) ones don't. But any combination that might give this?

square root of 3?

I just finished taking a symbolic logic class

But we didn't study what you are asking about

Sorry brah

I don't think so... the last statement, I believe, is not congruent with the other 3.

yeh bro you just gotta combine the inputs into a NAND/ then take that output, and AND it with the second input. Output of the second AND meets your stated truth table. see below showing the exact outcome for an A,B 0,1 pair - all other input combinations result in a T/1 output.

p.S fuck you for making me think back 10 years to university days :sniper::sniper::sniper:

It's more math than logic.. If it's anything.

haha, what? Of course it's math.... "logic gate" has a specific meaningful definition, its not the general verb form of the word logic. it's just maths in a base-2 as opposed to base-10.

I made it to precalc and statistics. So I'm out.

yeh sorry man, re-reading my post makes me sound like a pretentious douche bag, I was really just LOL'ing at the "if its anything" part of your post... I mean of course it's "something", the shit does exist.
The whole logic thing might look hard or smart, but its not really. its just a little unusual and beyond the ken of the day-to-day. anyone could be taught it and just knowing some basic crap like this doesn't make you smarter than someone who doesn't

Well this got more replies than I expected.

Actually, (A | !B) gets that result. Friend answered it elsewhere. Couldn't believe how simple it was.

The easy answer is (A | !B), or (!A & B)

But you are saying (!(A & B) & B) ?
T,T, that gives (!(T & T) & T) -> !T & T -> F & T -> F. Which is wrong unless I'm missing something.

You're welcome. The only useful thing I learnt in uni.

It just boils down to T|*->T, and F&*->F

And how do you draw that as a logic gate diagram? You've just written the annotations

I'm just saying logic boils down to it, it's not the answer for my original question. As in, anything OR'ed with T, gives T. And anything AND'ed with F gives F. Just agreeing with you in that it's simple in essence and can be taught to anyone.
