Abstract:Few formal comparisons between fast Fourier transform (FFT) and digital period-amplitude (DPA) analyses of all-night electroencephalographic (EEG) data have been reported. However, the uses of both approaches have been reported widely in the sleep literature.
Objectives.We sought to quantitatively model the temporal dynamics of sleep EEG using FFT and DPA derivations of spectral estimates applied to the same set of raw data, then to determine the degree of statistical similarity or difference between the two s… Show more
