Discrete Fourier series
http://dbpedia.org/resource/Discrete_Fourier_series
In digital signal processing, the term Discrete Fourier series (DFS) is any periodic discrete-time signal comprising harmonically-related (i.e. Fourier) discrete real sinusoids or discrete complex exponentials, combined by a weighted summation. A specific example is the inverse discrete Fourier transform (inverse DFT).

离散傅里叶级数（DFS）与连续傅立叶级数相比有很大的区别。最大的不同在于离散时间傅里叶级数的系数序列是周期的。
