傅立叶变换的数学再认识

Recognition Mathematics Based on Fourier Transform

由极限和微积分的观点对傅立叶变换进行阐述。以泰勒公式为引导,结合级数理论,从数学上介绍了傅立叶级数、傅立叶变换、频谱以及对频谱分析的指导意义。

Fourier transform is introduced from the perspective of the limitation and the expansion. By introducing Taylor formula infinite series theory is combined, the Fourier series, Fourier transform, the spectrum are presented. It is effective for the spectrum analysis.
