Type and conversion
window_table :: (Integral n, Fractional a, Enum a) => n -> Window a -> Table a Source #
Generate an n element table from a (0,1) normalised window function.
Math
Window functions
rectangular :: Window a Source #
Unit (id) window, also known as a Dirichlet window.
triangular :: Fractional a => Window a Source #
Triangular window, ie. Bartlett window with zero end-points.
