Greetings,
I think here you are looking for someone to fit data into bessel function. Familiar with lowpass signal filter.
I understood your project description.
I am an expert in Electronics, Matlab and Mathematica, Statistics, Electrical Engineering, Machine Learning (ML), and I am interested in your project.
I am confident that I can do this with 100% accuracy and ready to start now!
But I want to know more about your project. So, can we discuss more?
Regards.
