# tf.contrib.signal.hann_window

tf.contrib.signal.hann_window(
window_length,
periodic=True,
dtype=tf.float32,
name=None
)


Generate a Hann window.

#### Args:

• window_length: A scalar Tensor indicating the window length to generate.
• periodic: A bool Tensor indicating whether to generate a periodic or symmetric window. Periodic windows are typically used for spectral analysis while symmetric windows are typically used for digital filter design.
• dtype: The data type to produce. Must be a floating point type.
• name: An optional name for the operation.

#### Returns:

A Tensor of shape [window_length] of type dtype.

#### Raises:

• ValueError: If dtype is not a floating point type.
