Two-pole Lowpass Filter, -6 dB Resonance (LOPAS2)
Using this filter is the same as using two one-pole lowpass filters in successive algorithm
blocks. Since its resonance is fixed at -6 dB, it’s also the same as using 2POLE LOWPASS with
the resonance set to -6 dB. You’d use this filter when you want a 12 dB per octave rolloff but
don’t need to set a resonance level. This would leave you free to use another DSP function in
the algorithm, since it’s a one-stage function.
