---To which I can only respond "stuff and nonsense, slick".
First, any properly done sampling system HAS to have an output filter, so what you're measuring without one isn't anything meaningful.
However, if y'all look at the spectrum of the signal before the output filter, y'all see the tone, the images, and the noise. Y'all won't see any harmonics like y'all would see if the dither didn't work.
So, no, y'all don't need an output filter for dither to work, but you certainly do need one to get reconstruction to work properly.
Please, please, go study this, and stop spreading mythology.
