A new IIR adaptive filter design using Tellegen's theorem

An IIR (infinite impulse response) adaptive filter algorithm which allows the use of arbitrary network structures is presented. The gradients are derived using a digital network extension of Tellegen's theorem which allows the use of exact instantaneous gradients. The algorithm is compared, by simulation, with the IIR LMS (least mean square) algorithm of Widrow (1975) and Stearns (1976).<
