Wavelet Amplitude Spectrum and Phase

Method: wavelet amplit. spectrum & phase

Compute the averaged wavelet spectrum using different wavelet functions and display the amplitudes and phases.

Morlet

This button selects the type of wavelet used for the transformation. Press the button to change the wavelet function. The wavelets Morlet, general Gaussian, Laplace, f0-deriv. Gaussian, Mexican Hat, Goupillaud and Morlet II are implemented.

f0

The fundamental wavelet frequency for diladation 1.

window width

The cutoff sigma value for the Gaussian wavelet windowing function.

spectrum bins

Number of spectrum bins equally distributed over the full frequency range. Note: The (maximum) analysis frame length is computed automatically because it depends on the frequency of the first (lowest) bin.

coef.

Exponent for the general Gaussian wavelet.
