I believe they are actually wrong there. Perhaps some information was taken out of the article. I believe that jitter above 40kHz but _below_ Fs/2 (8*44/2 kHz for an 8 times oversampling D/A) will be surpressed as it will be properly filtered out by the D/A. However, any jitter above Fs/2 will again fold down, but some of it will, of course, fold into the area which is filtered away). I'll check to see if I can find some more info on this. Interesting is the reasoning about one-bit DACs. Then we have interface jitter, which will allow very high frequency pollution to affect the clock. (Not the same as the jitter discussed earlier in that article which is jitter introduced directly at the clock.) -- P Floding ------------------------------------------------------------------------ P Floding's Profile: http://forums.slimdevices.com/member.php?userid=2932 View this thread: http://forums.slimdevices.com/showthread.php?t=32231 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
