There are always a lot of discussions going on about the evils of phase
shift, eg. how much oversampling do I have to do to reduce my analog filter
to 30 dB/octave with phase shift < 10 degrees. Can someone tell us if it
might be possible, knowing what the phase shift of the analog filter
will be, to precompensate in the digital domain? ie. before the signal is
converted back to analog (and subsequently filtered) could we not shift
the phase appropriately in the `other direction'?
