dqa.tasks.transformations.FFT#

class dqa.tasks.transformations.FFT(axis: int = -1, **kwargs)#

Performs the fast Fourier transform.

Returns an array of length (input_length) // 2 + 1 along the specified axis, as the fourier coefficients are symmetric for real-valued signals.

Parameters:: axis (int, default=-1) – The axis along which the fourier transform is performed.

Methods

finish()

Can perform actions that are required to clean up after the task has finished, e.g. close network connections etc.
