A Sound Processor for Cochlear Implant Using a Simple Dual Path Nonlinear Model of Basilar Membrane

<table>The frequency response of the proposed SDPN model when the center frequency is set to 1500 Hz. When the input amplitude is low, the contribution of the nonlinear pathway is relatively large so that the overall response shows a sharp frequency selectivity determined by the tip filter. As the amplitude increases, the contribution of linear pathway becomes dominant, and the overall frequency response therefore becomes broader.</table>
