>How would a DIY person measure the purity of a sine wave beyond using a
spectrum analyzer?  To give a figure of sine purity, of distortion (THD?) ?

I got some good info on this when I asked about it earlier this year.

Search here: http://search.retrosynth.com/synth-diy/

Yes, apparently I spelt 'techniques' wrong :)
