Résumé
The task of distinguishing nerve type for the activity acquired using the multi-electrode cuff presents a big interest in the possible applications of prosthesis control or functional electrical stimulation. In this paper, a method to evaluate the maximum expected performances of filters using two-dimensional spectral analysis is presented and tested on simulated extracellular potentials. These later are the result of a realistic model of an acquisition system developed from biophysiologic parameters and electrode/preamplifier model. The method is thus appropriate for characterizing filter based on velocity selective recording (VSR) method.
