Two-pole Lowpass Filter, -6 dB Resonance (LOPAS2)
Using this Þlter is the same as using two one-pole lowpass Þlters in successive algorithm
blocks. Since its resonance is Þxed at -6 dB, itÕs also the same as using 2POLE LOWPASS with
the resonance set to -6 dB. YouÕd use this Þlter when you want a 12 dB per octave rolloff but
donÕt need to set a resonance level. This would leave you free to use another DSP function in
the algorithm, since itÕs a one-stage function.
