Default thd analyzer-on-a-chip

this looks like it would make an interesting project..... a diy thd analyzer..........

i prefer the subtractive type (like the HP analyzers) or spectrum analysis, but this looks interesting. it's a filter type analyzer on a chip. i think it uses switched capacitor filters, since the measurement frequency is determined by the clock frequency.

oops pdf is too big.... here's the link:
