令 ,w(n)为高斯窗函数。试用matlab软件,取不同长度的窗函数,分别求x(n)的离散短时傅里叶变换,并进行信号重构。试讨论窗函数长度对时频分辨率、重构精度的影响。-Order, w (n) is Gaussian window function. Try matlab software, takes a different length of the window function, respectively, find x (n) short-time discrete Fourier transform, and signal reconstruction. Discuss the frequency resolution when the window function length on Reconstruction Precision.
