Discrete Fourier Transform of Windowing Functions
Wolfram Demonstrations Project · 2007
This Demonstration illustrates the frequency domain properties of various windows which are very useful in signal processing.All the windows presented here are even sequences (symmetric about the origin) with an odd number of points. An -point discrete Fourier transform (DFT) is of length where is a positive integer. If the length of the input sequence is less than then it is padded with trai;
