Patent ID: 8639359

Claim:
A method of generating electrode stimulation signals for an implanted multi-channel electrode array of a cochlear implant, the method comprising: processing an acoustic audio signal with a bank of filters, each filter in the bank of filters associated with at least one channel having an electrode, the bank of filters including a first band pass filter that produces a broadband signal b(t) with frequencies that substantially cover at least one of a pitch frequency range of 100 Hz to 400 Hz and a first format range of 400 Hz-1000 Hz; and sampling the broadband signal b(t) while preserving temporal fine structure information associated with b(t); activating at least one electrode associated with the first band pass filter with electrode stimulation signals based, at least in part, on the sampled broadband signal b(t); and activating at least one electrode associated with one or more filters other than the first band pass filter, the one or more filters producing signals having higher frequencies than broadband signal b(t), wherein activating at least one electrode associated with one or more filters other than the first band pass filter includes using a Continuous-Interleaved-Sampling strategy (CIS).
