#X text 103 370 Windowing functions are used with FFTs. These transform
the signal block-by-block into a spectral representation whose resolution
in both the frequency and time domains are proportional to their size
(as a power-of-two in PD). The different windows have different characteristics
in terms of stopband attenuation and noise bandwidth.;
