英语翻译
Approximation using superposition of functions has existed since the early 1800's when Joseph Fourier discovered that he could superpose sines and cosines to represent other functions.However,in wavelet analysis,the scale that we use to look at data plays a special role.Wavelet algorithms process data at different scales or resolutions.

答案

19世纪,约瑟夫·傅立叶发现了可以用含有正弦和余弦的叠加式子来表达其他函数,由此产生了使用方程叠加原理的近似法.然而,在小波分析法中,我们用来查看数据的量程（?这个要根据你的专业情况定）起到了特殊的作用.小波的算法中以不同的分辨率或量程来处理数据.
