Digital to Audio Conversion and Intro to Synthesis Powerpoint

This is the powerpoint I spent most of last week researching for. I think it can be improved upon/added to, so please leave any thoughts/comments you have!!

I was planning on doing Wavetables in this powerpoint, but I quickly realized that wavetables make much more sense when one knows the basics of music synthesis. So the next powerpoint will be on wavetables... or at least, that is once again the plan.
