摘　　要：提出了一种非线性耳蜗滤波器组的设计方法,设计的耳蜗滤波器组结构简单,易于实现,能模拟因输入信号电平的不同而引起的耳蜗滤波器的非线性特性,而且其特征参数能随着更新实验结果的出现灵活地加以修正。文中给出了设计细节以及具体的数字实现方法。This paper proposed a design method for the nonlinear cochlear filter-bank. Using this method, the structure of designed cochlear filter is simple and easy to be implemented. The designed filter will have the nonlinear characteristics in the responses of different input levels, and its parameters could be modified flexibly with some revelation of new experimental results. The design details and digital implemen tatien for the coehlear filter are also presented.
