electricpy.math.rfft(arr, dt=0.01, absolute=True, resample=True)[source]

RFFT Function.

This function is designed to evaluat the real FFT of a input signal in the form of an array or list.

Parameters:

  • arr (numpy.ndarray) – The input array representing the signal

  • dt (float, optional) – The time-step used for the array, default=0.01

  • absolute (bool, optional) – Control argument to force absolute values, default=True

  • resample (bool, optional) – Control argument specifying whether the FFT output should be resampled, or if it should have a specific resampling rate, default=True

Return type:

FFT Array
