  This class is derived form the BiquadCascade-class. It implements a 
  biquad-cascade consisting of 6 biquad-sections with fixed coeeficients. The 
  coefficients were obtained with MatLabs fdatool with the following
  design-specifications:
  
  Filter-Type:     Elliptic
  Order:           12
  Frequency-Units: Normalized to 0...1
  wpass:           0.9*0.25
  Magnitude-Units: dB
  Apass:           0.1
  Astop:           96
