一种适合在单片机上运行的快速傅里叶算法，大量采用查表方法。理解这个算法对实现电力谐波分析很有帮助。fft算法的经典应用，需要一定的数学知识！-Fit on a single chip running at the fast Fourier algorithm, a large number of look-up table method used. Understanding of this algorithm to achieve useful power harmonic analysis.

这是一个简单的，基于51单片机的FFT运算程序。使用AD采集,做了64个点的FFT，可以使用两块简单的点阵屏来观看效果。-This is a simple, based on 51 single chip FFT arithmetic program. Use AD collection, made 64 point FFT, can use two pieces of simple lattice screen to see effect.

51单片机，信号分析，FFT,8位单片机进行信号分析的尝试-51, signal analysis, FFT, 8-bit microcontroller attempt to signal analysis

使用STM32F103C8T6单片机实现了使用内部ADC对电压采样，并计算FFT，通过串口发送至上位机。-Use STM32F103C8T6 MCU using the internal ADC sampling of voltage and calculate the FFT, first bit machine sent through the serial port.
