ABSTRACT
In this paper we design a Finite-Impulse-Response (FIR) fil-
ter to enforce the so-called Strictly-Positive-Realness (SPR)
condition in an adaptive Infinite-Impulse-Response (IIR)
filtering context. The paper results may then be used to
guarantee the convergence of pseudolinear regression IIR
adaptive algorithms.
1. INTRODUCTION
Many of the adaptive IIR filtering approaches can be clas-
sified into two categories: (1) the equation-error formula-
