Functions

func Kaiser

func Kaiser(M int, beta float64, sym bool) ([]float64, error)

Kaiser returns the Kaiser window Parameters:

• M: the number of points in the window
• beta: the beta parameter, used if sym is false.
• sym: if true, generates a symmetric window, for use in filter design. Otherwise, generates a periodic window, for use in spectral analysis.

Returns:

• out: the window, with the maximum value normalized to 1 (though the value 1 does not appear if sym is True)

func KaiserBesselDerived

func KaiserBesselDerived(M int, beta float64, sym bool) ([]float64, error)

KaiserBesselDerived returns the Kaiser-Bessel window Parameters:

• M: the number of points in the window
• beta: the beta parameter, used if sym is false.
• sym: if true, generates a symmetric window, for use in filter design. Otherwise, generates a periodic window, for use in spectral analysis.

Returns:

• out: the window, with the maximum value normalized to 1 (though the value 1 does not appear if sym is True)
