Claim:
1. A system for activating electrodes, the system including: a multi-channel electrode array; and a stimulator for activating electrodes in the electrode array using channel specific sampling sequences, each channel specific sampling sequence associated with a channel in the multi-channel electrode array, and having a predefined duration, pulse amplitude distribution, and number of pulses, the pulse amplitudes of the channel specific sampling sequence derived by sampling a sinusoidal signal, wherein the stimulator is configured to apply a weighting factor to each channel specific sampling sequence so as to create a weighted channel specific sampling sequence for each electrode in the electrode array, the weighting factor based, at least in part, on an acoustic representative electrical signal, and wherein the stimulator is configured to simultaneously activate at least two electrodes in the electrode array using sign correlated pulses, the sign-correlated pulses based on:
