Abstract
Methods and systems are disclosed for determining an amplitude of one or more stimulation signals corresponding to a subject signal for use by a stimulating medical device having a first group of stimulation channels mapping to a second group of electrodes, respectively. Such a method, for example, includes: obtaining the subject signal; filtering the subject signal with a first plurality of band-pass filters (BPFs) having substantially contiguous pass-bands, respectively, to obtain a first set of one or more signals; selecting at least one of the stimulation channels based on the first set; filtering the subject signal with a second plurality of BPFs having significantly overlapping pass-bands, respectively, to obtain a second set of one or more signals; and determining at least one stimulation amplitude for the at least one selected stimulation channel, respectively, based on the second set of signals.
