[sdiy] Q and Synth Filters

[Glen]

Is the term "Q" always something that makes sense, and can always be
calculated, within the context of synth filters? I realize the concept of
"Q" applies very well to a bandpass filter, and probably to LP and HP as
well, but can the concept be applied literally to all the synth filter
topologies?

Finally, how is Q measured for the various filter types?


thanks,
Glen
