AND Gate

[Dark_Sniper*]

Does anyone know here what a AND gate is ? I have to draw one for Tech-Systems class and i don't know what one looks like

My powers of GOOGLE-FU as come up with this :-

Check out http://www.c-sharpcorner.com/Code/2003/Feb/GAAdderDesign.asp
Scroll down a bit for
NOT,

AND,

OR

and XOR

I hope this helps

yea i know that one lol, i did not say it the right way like a circuit type of thing.

that kind of thing

You got me on that one............ Not sure.

It is a device used in digital circuitry. Lets say that if you have an and gate, as Harper showed, and you have a 1 (as in binary 1) on input a, and a 0 on input b, the output would be 0. Think of an and gate as a multiplication gate. If you have 1 and 1 (1 times 1), you will have a 1 as an output.

What else do you want to know about it? I seem to remember all this stuff from my college days Ask away!

yea i know that part im jsut looking for a diagram thingy lol. Such a pain.

Dude I'm taking electronics right now, they gave you all the advice I can think of, I have no idea what you're asking. That IS the diagram.

it is wrong to think of it as a multiplication gate because:

in multiplication 0 x 0 = 0
whereas in electronics 0 AND 0 = 1 (false AND false is TRUE)

Im lost here. My dad has degrees in that crap i dont lol.

it's a transistor. you put in 2 inputs, and it generates an output. the output depends on the transistor.

AND
INPUT --------> OUTPUT
0, 0 --------------> 0
1, 0 --------------> 0
0, 1 --------------> 0
1, 1 --------------> 1

other transistors:

OR
INPUT --------> OUTPUT
0, 0 --------------> 0
1, 0 --------------> 1
0, 1 --------------> 1
1, 1 --------------> 1

NAND
INPUT --------> OUTPUT
0, 0 --------------> 1
1, 0 --------------> 1
0, 1 --------------> 1
1, 1 --------------> 0

NOR
INPUT --------> OUTPUT
0, 0 --------------> 1
1, 0 --------------> 0
0, 1 --------------> 0
1, 1 --------------> 0

XOR
INPUT --------> OUTPUT
0, 0 --------------> 0
1, 0 --------------> 1
0, 1 --------------> 1
1, 1 --------------> 0

XNOR
INPUT --------> OUTPUT
0, 0 --------------> 1
1, 0 --------------> 0
0, 1 --------------> 0
1, 1 --------------> 1
