Abstract
In this paper we present a new stabilization procedure based on the spectral factorization capability of PLSI (planar least square inverse) polynomials of semicausal form. It is not involved with an intermediate PLSI polynomial since stabilization of an unstable filter is directly obtained from its autocorrelation function. We also introduce a measure of amplitude distortion due to stabilization. The new procedure offers a remedy for flaws in Shanks´ original procedure for stabilization.
