摘要
离散傅立叶变换是信号分析中的一种重要手段,它将时域信号转换成频域信号。本文主要介绍离散傅立叶变换的两种算法,即时域抽取法,频域抽取法,并对两种算法进行比较。
The Discrete Fourier Transform（DFT）, which can convert signal-In-Time to signal-In-Frequency, is a very important method in signal analysis. This paper mainly introduces two algorithms realizing the DFT, i.e.Decimation-In-Time and Decimation-In-Frequency. The comparison between them is also made.
