摘要
快速傅立叶变换(FFT)是将离散的数字信号信号从时域变换到频域的一种常用方法,广泛运用于各种数字信号系统。本文介绍了FFT算法的原理,并结合Microchip公司的dsPIC33系列芯片,阐述了基于硬件DSP模块的FFT算法的实现。
Fast Fourier Transform Algorithm (FFT) is a common method for transforming discrete digital signals from time domain to frequency domain, which is widely used in all kinds of digital signal system. This paper introduces the principle of FFT Algorithm and combined with the chip of dsPIC33 series from Microchip Company, it elaborates the realization of FFT Algorithm based on hardware DSP.
