NO The DAC generates a stepped ladder function, the reconstruction filter turns this into the recovered waveform. In the case of many modern, oversampling DACs, the reconstruction filter is a simple 2nd order analogue filter. No limited number of calculations. Yes the transform theory for the filter is a set of infinite sums, but the filter is a filter. -- DaveWr ------------------------------------------------------------------------ DaveWr's Profile: http://forums.slimdevices.com/member.php?userid=9331 View this thread: http://forums.slimdevices.com/showthread.php?t=93990 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
