This guy has a lot more "snow" in his decay signal than mine has, but it is suitable to demonstrate the principle. Looking over his site, it looks like he is using a similar approach as I am thinking of taking, as far as using a MPU to analyze the signal for discrimination principles.

I wish. I have an old non-digital 100mhz quad channel B&K, and it doesn't have storage features. I used to use an old Emerson digital camera to take screen shots, but it has gone the way of the dodo. My new one just catches screen glare.
I keep thinking I have seen some shots online though...
3VO pointed out something to me in chat. The decay lasts for a few milliseconds on the short decay signals. (Unless I misread my scope). For a short decay, there are usually 20-30 oscillations. Therefore, I would need to take a sample at least 30 times per millisecond. (Again, thank you 3VO. I...
First, I know that it is next to impossible to provide a solution, without first knowing what is being attempted. Therefore, I will give a heads up of my project.
I do not know how many here are familiar with metal detection circuits, but a common problem with these circuits is discrimination...
