AND gate
Just as we can create NOT logic from a NAND gate, without the AND conditions, we can create a circuit that exemplifies the truth conditions of AND just by discluding those of those of NOT.
When we attach two NAND gates in sequence connected to two switches as input this creates the following binary conditions:
A B Output
_ _ _____
1 1 1 (1)
1 0 0 (2)
0 1 0 (3)
0 0 0 (4)
Which is identical to the truth table for AND :
p q p & q
_ _ _____
t t t (1)
t f f (2)
f t f (3)
f f f (4)
An AND at 0 0 :
AND at 1 0 or 0 1 :
AND at 1 1
Symbol for AND gate
It's very similar to NAND so be careful not to confuse it
