Figure 4From: WAVOS: a MATLAB toolkit for wavelet analysis and visualization of oscillatory systemsSynthetic signal A. Synthetic signal A; decreasing period from 24 to 18 hours, stable baseline, decaying amplitude. Shifting periods are not effectively detectable by the Fourier transform, and will lead to poor estimates of the period. In contrast, analysis by the CWTyields local estimates of the period.Back to article page
