Abstract
A hearing prosthesis, including receiver means for receiving a signal representative of a signal over a frequency range; a first filter bank, having a relatively higher resolution, adapted to process said received signal and produce a first set of channel outputs relating to a selected region or regions of said frequency range; and a second filter bank having a relatively lower resolution, adapted to process said received signal and produce a second set of channel outputs relating to at least the rest of said frequency range; combination means to combine the first and second sets of channel outputs, and processing means operative upon the combined outputs so as to produce a set of stimulation signals for said hearing prosthesis.
