What I want to create is a simple logic gate that doesn't actually perform any logic, but instead simply repeats the given signal. I want to do this so that I can have a one-way wire.
Some ideas that I've thought of, but I'm not sure if they're efficient, or which one is more efficient:
A NOT gate plugged into a NOT gate.
An AND gate with both of the inputs as the same wire
An OR gate with both of the inputs as the same wire.
