WA Analytic Wavelet Transform Details

The AWT is a special case of the CWT with the complex-valued Morlet wavelet, also called the Gabor wavelet. The following equation defines the complex-valued Morlet wavelet:

where is the standard deviation of the Gaussian envelope of the mother wavelet, and is the central frequency of the mother wavelet, which is in this VI.
