scipy.signal.triang

scipy.signal.triang(M, sym=True)[source]

Return a triangular window.

Parameters :

M : int

Number of points in the output window. If zero or less, an empty array is returned.

sym : bool, optional

When True, generates a symmetric window, for use in filter design. When False, generates a periodic window, for use in spectral analysis.

Returns :

w : ndarray

The window, with the maximum value normalized to 1 (though the value 1 does not appear if the number of samples is even and sym is True).
