[sdiy] filters with independent resonance 'location'

[John Potter]

Interesting - Yeah, you do always see resonant peaks at the cutoff freq.
(ie. http://www.doepfer.de/a100_man/a120_d2.gif).  I bet two cascaded
resonant filters or a parametric EQ before a filter would give you that
effect - unfortunately, I don't have a scope to verify.  Interested to hear
what others have to say.

Subject: [sdiy] filters with independent resonance 'location'


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
