Abstract

The model consists of independent frequency-channels the amplitude-frequency characteristics (AFC) of which are assigned by the investigator. The phase characteristics are computed. Concrete minimum-phase model is described and illustrated. The temporal and frequency characteristics of this model are consistent with experimental data on peripheral auditory system. The AFC can be easily reformed, so the model is convenient for investigation of functional models of peripheral auditory analysis.

摘要

该模型由独立的频率通道组成,研究人员可指定其幅频特性(AFC)。相位特性通过计算得出。文中描述并说明了具体的最小相位模型。该模型的时间和频率特性与外周听觉系统的实验数据一致。AFC可轻松进行调整,因此该模型便于对外周听觉分析的功能模型展开研究。
