Are you sure this is so bad, compared to a good CD player? You have to be careful with these number - jitter has a spectrum, so it can't be quantified completely with a single number. In this case, the low numbers he quotes are the root-mean-square values. That is, take a clock edge, subtract the time it occurred from the ideal time (in picoseconds), square that, sum over all edges, and then take the square root. That's almost certainly the standard number you'd see quoted anywhere, and it's very low, from what I've seen. The peak-peak values are the largest values of the deviation from ideal that occur anywhere in the sample set (he doesn't say how long it is, but it's probably very very long). So when you compare, make sure you're comparing apples to apples! -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=25188 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
