Recently, I have started implementing CWT on accelerometer signals. A method stated in an article stated that the signal is smoothed by integrating and then differentiating the signal using a Gaussian CWT. I am trying to translate that into a python code but I dont quite know how. How can we differentiate and integrate signal using gaussian CWT? Any help ?
