基本英英例句
傅里叶级数
Noun:
the sum of a series of trigonometric expressions; used in the analysis of periodic functionsIf the floor were infinite in extent, the mathematical distribution of reflected light could be regarded in terms of a two-dimensional Fourier series.如果地板的广度是无限的，那么可以用一个二维傅里叶级数来表示反射光的数学分布。
This paper analyzes the spectral characteristic of the synthesized waveform by use of the Fourier Series,and discusses the spurious spectrum of the phase truncation errors.本文用傅里叶级数的方法分析了合成波形的频谱特性，并对由于相位截断引起的杂散谱作了讨论。
