Return the discrete Fourier Transform sample frequencies for use with rfft() and irfft().

The returned array contains the non-negative frequency terms in the range [0, floor(n/2)].

Parameters:

  • n (int) – Window length.

  • d (float, optional) – Sample spacing. The default is 1.0.

Returns:

The sample frequencies as a one-dimensional array of type float32.

Return type:

array
