NOT logic. Question.

00:53:13

Don't be mean. I've not been to school for this stuff, just a hobbyist. 
 So... what exactly is the purpose of these NOT gates? It appears to be converting AC to DC. In what type of device would i find these? Sorry for the dumb question.

You can see NOT gates in almost all digital circuits. Just look up de-morgan's theorem to get an idea behind how it's used.

Increase sinusoidal voltage to 5volt and see in oscilloscope (eye symbol) than you can see as input goes high output goes low and vice versa and connect resistor before led .

A logic gate (NOT, AND, OR and the rest) isn't usually used with an AC voltage. They're used with DC, where a voltage means a binary "1" and a lack of a voltage means "0". Specifically, NOT will invert its input, so an input of "0" gives an output of "1" and vice versa.
