aspcore.fouriertransform.rfft

aspcore.fouriertransform.rfft(time_sig, n=None)

Computes the real FFT

Parameters:

• time_sig (ndarray) – The signal to be transformed. The last axis should correspond to time

• n (int, optional) – length of the FFT. If None, the length is the length of the last axis of time_sig

Returns:

freq_signal – The transformed signal

Return type:

ndarray

Notes

Corresponds to numpy.fft.rfft, but with the time convention used in this package.
