Abstract: A filter design method isolates parasitic zeros in a modelled response by comparison with a representation of a target response, and computes an adjusted representation of the target response corresponding to an implementation of the adjusted target polynomial representation according to a desired filter type and incorporating the parasitic zeros thus isolated. The Parasitic zeros are then removed from this adjusted target polynomial representation, and also from the polynomial representation of the modelled response, and the two resulting representations used as the basis of an error function. This error function may then drive an iterative convergence minimising the error function, for example based on a stepwise convergence of parameters such as dimension values in a three dimensional model implementing each representation.
