摘要
本系统为所研制的“喉动态观测分析仪”中重要组成部分,主要实现对声音信号的自适应放大和滤波功能,提供给单片机主控系统所需信号,以提取声音的基频,控制闪光观察声带振动的动相和静相。系统包括硬件电路和软件系统。
As the most important part of the the Larynx Dynamic Observing and Analyzing System, this system performs the self-adapting amplifying and filtering of the voice signals. It also supplies the signals, which a single-chip microprocessor need to fulfill the digitize control of flash observing of the movement of vocal cords. It includes hardware and software systems.
