AddWindowDFT
- 加窗离散傅立叶变换，用DFT对离散信号进行谱分析，通过选用不同的加窗函数来抑制信号截断造成的频谱泄漏-windowed discrete Fourier transform, DFT right discrete signal spectral analysis, the increase in the alternative window function to curb the disconnect signal leakage spectrum
window.m
- This scr ipt calculate the Fourier transform of a Rectangular window of 64 points using an aproximation with a DFT of 1024 points,as well as calculates for differents values of f0 and f1 the module of the frecuency response of the windowed signal.
