mindspore.ops.hamming_window

mindspore.ops.hamming_window(window_length, periodic=True, alpha=0.54, beta=0.46, *, dtype=None)[source]

Hamming window function.

\[w[n]=\alpha − \beta \cos \left( \frac{2 \pi n}{N - 1} \right),\]

where \(N\) is the full window size, and n is natural number less than \(N\) :[0, 1, …, N-1].

Parameters

window_length (int) – The size of window.
periodic (bool, optional) – If True , return a periodic window. If False, return a symmetric window. Default True .
alpha (float, optional) – The coefficient α. Default 0.54 .
beta (float, optional) – The coefficient β. Default 0.46 .

Keyword Arguments

dtype (mindspore.dtype, optional) – The data type specified. Default None .

Returns

A 1-D tensor.
