Taylor, Professor Response For k=2, for example, the poles are at the location of the zeros of W122 which implies polezero calculation. However, even in floating point the production of W122 contains some error meaning that exact polezero is unrealistic. The pole maybe conditionally unstable. If a tone arrives at the 4th harmonic, your dead. It is for this reason that the poles of the resonator are force to be “slightly” interior to the unit circle. FFT#2  2...
