Detailed Description

template<class T>
class HLowpassBiQuad< T >

Calculate the normalized coefficients for a generic lowpass biquad filter.

Given the required cutoff frequency, the sampling frequency and the required quality and passband gain, calculates the coefficients of a 2. order (biquad) IIR filter.

This is not a filter - use this type as the generic parameter BIQUAD when creating a HBiQuadFilter.
