>Is that the basic operating principle of DC->AC conversion?

it's just one way to do it. it's very far from accurate, but it's popular coz it's easy and cheap.

>is there any way to generate a sin wave that doesn't involve processing another wave?

there are 1001 ways to do it. one very easy, and surprisingly accurate way is to put a microphone in front of your face and say a vowel.

Is there some super pure sinewave generator that has a huge range (tuneable with a potentiometer, not by changing caps)? I need one.
