摘　　要：介绍了一种低成本基于８０９８单片机的实时周期信号频谱分析系统，分析了其硬件组成和各部分功能。该系统采用基于同步采样的ＦＦＴ测量方法，频率范围为１６．７－１００Ｈｚ。通过对比实验表明，该方法可以准确地分析出周期信号中所含有的谐波分量。此系统已被应用在某振动时效装置。A type of spectrum analysis system of periodic signals based on 8098 single chip microcomputer is designed, which has low-cost and real-time property. Its hardware circuit and function of component are presented. The method of fast Fourier analysis based synchronous sampling is used in this system. By the comparison test, it is verified that this method can correctly analyzes spectral component of periodic signals. The system has been applied into vibratory stress relief devices, which has acquired satisfied results.
