Abstract :
Convergence of a recently developed frequency-domain adaptive pole-zero infinite impulse response (IIR) filtering algorithm by J.J. Shynk and R.P. Gooch (1986) is studied. A technique using ordinary differential equations (ODE) is modified and applied to this algorithm. It is shown that under certain statistical conditions the algorithm converges in probability to an associated ODE which in turn converges to a local minimum of its performance surface
