摘要

This paper presents the IIR adaptive digital filter. The maximum-phase shift component of the unknown system is estimated by an allpass adaptive digital filter. The impulse response of the residual part of the system is concentrate in the neighborhood of time n=0 and is then estimated by a transversal adaptive digital filter. As a first step the transfer function of the unknown system is represented by an orthogonal function that contains an allpass function and has poles only at the origin of the z-plane.
