Logic Gates

Intro
Logic gates are the meat and potatoes of digital electronics, and from them you can derive pretty much all digital chips (flip flops, counters, binary to decimal, 8 segment decoders etc..)

NOT
The NOT gate is the simplest of all logic gates. It inverts the input signal.

AND
The AND gate returns a positive signal if both inputs are positive

OR
The OR gate returns positive if either inputs or both inputs are positive.

XOR
The XOR gate returns positive if and only if either of the inputs are positive, and not both.

Gates prefixed with N-
Gates with 'N' before them act as if there is a NOT gate placed after the output of the standard gate. Be careful in noting that an NAND or XNOR gate is not a replacement for a AND OR or XOR gate with just one of the inputs negated by the NOT gate.

Advanced Concepts
When logic gates are combined in certain ways, special properties can be achieved (of which some of them are provided as chips in the app)
