Expand description
A collection of window functions.
Functions
A Bartlett window of a given length.
A Blackman window of a given length. If periodic is true a periodic
window is returned, otherwise a symmetric window. See gen_cos for more details.
A Gaussian window of a given length with width factor alpha, which is
inversely proportional to the standard deviation.
Note that sometimes, the width of a Gaussian window is specified in terms of
a parameter that is proportional to the standard deviation (inversely proportional to alpha).
A generalized cosine window of a given length with coefficients coeffs.
If periodic is false, a symmetric filter is returned, which is suitable for
filter design. If periodic is true, a perfect periodic window is
returned, which is useful for spectral analysis. The periodic window is generated
by computing a window of length len+1 and then truncating it to the first len taps.
A Hamming window of a given length. If periodic is true a periodic
window is returned, otherwise a symmetric window. See gen_cos for more details.
A Hann window of a given length (sometimes also referred to as Hanning window).
If periodic is true a periodic window is returned, otherwise a symmetric window.
See gen_cos for more details.
A Kaiser window of a given length and shape parameter.
A rectangular window of a given length.
