Then the next question is of course: in those cases where

Provided that what you want is the same phase angle on
Hi Fons,
Thanks for the reply, and from vacation no less.

To understand why you can't chage the phase of DC at an even more

Hi all,
During the last days, I looked into phase-ration: components of a signal
are delayed differently depending on their frequency.
A good write up on the subject can be found at [1], and a commercial
tool is available from [2].
The interesting aspect is that phase rotation does not alter
