The Discrete Fourier Transform, Part 4: Spectral Leakage
By: Douglas Lyon
Abstract
Windowing modulates the input signal so that the spectral leakage is evened out (spreading on-bucket signals more and off- bucket signals less). Thus, windowing reduces the amplitude of the samples at the beginning and end of the window, altering leakage.
