ab: Summary: Direct synthesis of recursive digital filters, whose
    characteristic function belongs to the new IIR filters class, is
    described in this article. Attenuation characteristic in the passband
    lies between the Butterworth’s and the Elliptic’s attenuation
    characteristics. All zeros of transfer function are placed on the unit
    circle so that the condition for complementary decomposition is
    fulfilled. Complementary decomposition into parallel connection of two
    allpass filters is performed. Then, lowpass filter is obtained summing
    these two filters and its complementary highpass filter - by their
    subtraction. The main advantage of this kind of filters is its smaller
    sensitivity to digital word length change compared to standard filters.
