Detailed Description

TTAllpass2c is a second-order building-block allpass filter.

Essentially the same as TTAllpass2a, but with some signs flipped. Based on Fredric J. Harris (2004): Multirate Signal Processing for Communication Systems, Prentice Hall, Chapter 10, Figure 43.

Difference equation:

y(n) = -e_2 x(n) - e_1 x(n-1) - x(n-2  -  e_1 y(n-1) - e_2 y(n-2)

Transfer function:

         -e_2  -  e_1 Z^(-1)  -  Z^(-2)
H(Z) = ---------------------------------
        1  +  e_1 Z^(-1)  +  e_2 Z^(-2)
