ABSTRACT:
An improved processing approach is disclosed in order to allow for different rates of stimulation to be used for different electrodes in a multi-electrode cochlear implant. When the incoming signal is processed by filter array (35), each channel is processed to determine amplitude (37) and to estimate the period of the signal in that channel (39). The amplitude and period information is used to determine which electrode is stimulated, and the timing of that stimulation.
