用8098单片机实现FFT运算

Calculation of FFT by Singl Chip Controller 8098

本文讨论用８０９８单片机实现快速富里叶变换（ＦＦＴ）的方法。文中的算法程序用３２点复函数的变换计算６４个实函数样本点，并采用Ｈａｎｎｉｎｇ窗加以处理。

This paper discusses how FFT can be calculated using 8098 microcontroller, how to perform the FFT of two real functions at the same time by using the imaginary input values to the FFT for the second real function, and how to use the Hanning window to reduce spectral leakage。
