基于傅立叶变换的积分算法研究

Study on Integral Algorithm Based on Fourier Transform

在信号分析与处理中,常涉及的积分变换是傅里叶变换(FT)、傅里叶级数(FST)、傅里叶Z变换(FZT)及离散付里叶变换(DFT)。本文通过分析FT与FST、FZT、DFT的关系,提出一种基于FT计算FST、FZT、DFT的新算法,并通过例子说明这种算法的实用性。

In Linear system, Fourier Transform (FT), Fourier Series (FST), Fourier Z Transform (FZT) and Discrete Fourier Transform (DFT) are used to analyze and process signals. In this paper, a new algorithm based on FT has been proposed by analyzing the relationships among FT, FST, FZT and DFT. The practicality of the algorithm is illustrated.
