Examples of frequency spectra used for analysis for CFAE with two closely-spaced frequency components at the low end of range. A. The power spectrum using the new technique in the range 1–12 Hz. B. A close-up of the power spectrum with a range of 2 Hz. The parameters used to determine whether the synthetic frequency components are resolved are shown. C. The Fourier power spectrum in the range 1–12 Hz. D. A close-up of the Fourier power spectrum with a range of 2 Hz. The synthetic frequency components are not resolved in the Fourier spectrum.
