Detailed Description

template<class Numeric, class Coeff = float_type>
class SPUC::iir_allpass1< Numeric, Coeff >

Template Class for IIR Filter using 2 1st order sections.

The filter is a combination of 2 Allpass sections of the form G(z) = (a*z*z + 1)/(z*z+a) so that the overall H(z) is H(z) = 1/z*G(z,a0) + G(z,a1) The combination of these two allpass functions result in a lowpass/highpass complementary pair. The class only uses the low pass filter. This class needs the allpass_1 class
