Synchrosqueezed STFT phase transform
Synchrosqueezed STFT paper, Synchrosqueezing based Recovery of Instantaneous Frequency from Nonuniform Samples, defines STFT phase transform as:
$$
w(u, \xi) = \xi - \frac{\partial_tS_{g}f(u, \xi)}{j2\...

Why does a synchrosqueezed wavelet transform show oscillating behavior?
This question came up in the context of the ssqueezepy library. As a basic experiment I did compute the synchrosqueezed wavelet transform of three basic signals:
A ...

How to Map CWT to Synchrosqueezed wavelet transform?
I don't understand the mapping time-scale plane to the time-frequency plane in synchrosqueezed wavelet transform, i.e. $(3)$. You can find the paper here.
For the given signal of $x(t)$ and mother ...
