source: /scipy/signal/_spectral_py.py :2346

Signature

   def     _fft_helper (    x    ,    win    ,    detrend_func    ,    nperseg    ,    noverlap    ,    nfft    ,    sides      )

Summary

Calculate windowed FFT, for internal use by scipy.signal._spectral_helper.

Extended Summary

This is a helper function that does the main FFT calculation for _spectral helper. All input validation is performed there, and the data axis is assumed to be the last axis of x. It is not designed to be called externally. The windows are not averaged over; the result from each window is returned.

Returns

result : ndarray: Array of FFT data
