The solution is to put a HP filter on the input and disable the input during transients. Similar circuit solutions existed in the early days of pi metal detectors. But I don't like this solution, partly because turning the input on and off itself causes transients.
I wonder if you have found a simple and elegant solution to this problem?
P.S. and in the picture, I think, high-frequency noise is depicted against the background of a voltage drop in the coil. I don’t know how this relates to low-frequency noise filtering.
