Summary:The main purpose of this paper is to present some experimental results concerning the adaptation of the pole position of the lattice version of the Laguerre filter. Basically, we propose the adaptation of the Laguerre-lattice parameters with the GAL-L algorithm, and the adaptation of the pole with a suitable sign algorithm. An example and suggestions about how to attempt to avoid local minima (with respect to the pole position) are also given.
