| 摘 要： | 在频谱分析实现方法的基础上,设计出一种基于FFT算法的频谱分析系统。本系统以ADμC812为核心,在Quick Start环境下以C语言编程实现频谱分析算法。系统通过快速傅里叶变换运算将被测信号分解成分立的频率分量,并采用数字方法直接由模拟/数字转换器（ADC）对输入信号取样,再经处理后获得频谱分布图。文中给出了该系统的总体结构框图,部分硬件电路及软件算法流程图。仿真实验结果表明这种设计方法具有高精度、低功耗、实时反应迅速和可靠性强等特点。

| Abstract: | An spectrum analysis system is designed based on depth research of DFT realization. ADμC812 is used as core processor in the system, and the analysis program is compiled by using C language based on Quick Start. spectrum of sub-device operation will be measured through the Fourier decomposition signal frequency components of the legislation weight based on fast Fourier transform, and used directly by the number of analog/digital converter （ADC） to the input signal sampling, and then treated Access to the spectrum distribution. The article presented the general structure scheme, a part of hardware circuit and software flow chart. The result of the simulation proved that the system was equipped with advantages such like high precision, low power dissipation, quick real-time response, great reliability and so on. |
