You are wrong. a ADC quantifies the amplitude of the signal at the processing time. They do not record the tangent or any derivitave. > The second is the time-related errors. Timing is critical, but I've not seen any evidence that an ADC is not accurate with regard to timing (really phase here). Most, if not all, of the so called digital distortion is either quantification errors, or, and most likely, the result of the brutal anti-aliasing filters in the analogue chain before the ADC sees the signal. But this thread seems to be more theology than reality. -- Pat Farrell http://www.pfarrell.com/ _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
