For each condition of dead region size, electrodes that are disabled (Disb.) or enabled (Enb.) are indicated in the first and second columns, respectively. Cutoff frequencies for enabled electrodes are shown in the third column for each condition of dead region size. The same analysis filter cutoff frequencies were used for the “redistributed” vocoder signal processing.
