- CosineWindow is a window function typically used in signal processing applications where data needs to be processed in short segments.
- Window functions have a smoothing effect by gradually tapering data values to zero at the ends of each segment.
- CosineWindow[x,α] is equal to for and 0 otherwise.
- CosineWindow[x] is equivalent to CosineWindow[x,1].
- CosineWindow automatically threads over lists.
