| Abstract(in English) | Adaptive infinite impulse response(IIR) digital filter implemented using cascades of allpass filters and a finite impulse response(FIR) filter, has the property of its poles converging to those of the unknown system. It has been mentioned that there is a need of estimating the transfer level of the unknown system separately in order to allow for such a kind of convergence. In this paper we analyze the convergence of the poles of the ADF when allpass section is represented using first order filters, and the unknown system has only real poles. Analysis presented shows that it is possible for the poles of the ADF to converge to those of the unknown system even if the transfer level is not estimated separately. Simulation results, also confirms this analysis. |
