mlx.core.blackman

blackman(M: int, *, stream: None | Stream | Device = None) → array

Return the Blackman window.

The Blackman window is a taper formed by using the first three terms of a summation of cosines.

\[w(n) = 0.42 - 0.5 \cos\left(\frac{2\pi n}{M-1}\right) + 0.08 \cos\left(\frac{4\pi n}{M-1}\right) \qquad 0 \le n \le M-1\]

Parameters:

M (int) – Number of points in the output window.

Returns:

The window, with the maximum value normalized to one (the value one

appears only if the number of samples is odd).

Return type:

array
