| Abstract(in English) | Adaptive infinite impulse response (IIR) digital filter implemented using a cascade of second order direct form allpass filters and a finite impulse response (FIR) filter, has the property of its poles converging to those of the unknown system. In this paper we propose a different way of implementing the adaptive allpass-FIR digital filter using an allpass filter with minimum number of multipliers. We then derive an adaptive algorithm, which does not increase the overall complexity of the adaptive digital filter (ADF). The proposed structure and algorithm exhibit a kind of orthogonality, which ensures convergence of the poles of the ADF to those of the unknown system. Simulation results confirm this convergence. |
