Examples of frequency spectra used for analysis for CFAE with two closely-spaced frequency components at the high end of range. Panels correspond to those in Figure 3. The synthetic frequency components reside at approximately 8.5 Hz, and are resolved by the new technique (panel B). Measurement parameters are shown. The synthetic frequency components are not resolved by Fourier analysis (panel D).
