Resonant Filter Equalizer

The Resonant Filter Equalizer creates unique tone control by combining a high pass filter, low pass filter, and middle equalizer. Both filters have their own resonance control, allowing a bump at the cutoff frequency, accentuating the effect of the filters. The semi-parametric middle eq includes a variable frequency control. The resonance of the filters ranges from -3dB all the way up to +15dB. The -3dB setting is what you would expect from a standard, non-resonant filter. Adding resonance to the filters boosts the level of the cutoff frequency. The filters have a slope of -12 dB/octave. The filters are the same in performance to the other standard Broughton filters, with the added ability of increasing resonance.
