[sdiy] filters with independent resonance 'location'

[Jeffrey Pontius]

In general, a typical lowpass or highpass filter has the resonance set
around the cutoff frequency.  Are there filters available, and if not
available could one be reasonable constructed, that would allow the
resonance 'location' to be set independently of the cutoff frequency?

This is certainly not a new idea, but I have not seen or read about such a
filter.
Thanks, Jeff
