Quote:as for filter done with high Q components - if you can not get it in the real world, whats the point of designing it in the first place?
whats the point? Its a necessary step to understanding the order/ realizability .
You should be saying, "if it does not work with ideal Q components whats the point of designing it with real world components? "
Even Zeverev uses ideal Q to develop the prototype filter prior to scaling. Its a necessary step to make an ideal filter then add the reality of self resonance and Q degradation.
