+#X text 102 394 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.;
+#X text 102 258 SIGNAL: the height (amplitude) of the window is controlled
