Abstract :
The relative amplitudes of sinusoids are determined by calculating the ratio of the amplitudes of the Morlet continuous wavelet transform (CWT) at one time and only at the scales that are the inverse of the signal frequencies and multiplying that ratio by the square root of the inverse ratio of the scales
