Sorry if you don't like questions. :)

I write AudioUnit plugins that utilize oversampling techniques, I design DSP-based hardware that runs with sample rates as high as 6 MHz, and I design PCBs with pure analog circuits. All of my questions are driven by serious, hands-on knowledge - and a desire to learn about things I haven't tried yet. I also try to understand how the gear that I buy works, because I don't have time to design things that have already been mass-produced. None of this is courtroom or Wikipedia focused.

Just so's ya know...
