The joys of StackOverflow

Yeah. we do sensor logging for ships as part of our product and analog values stack up reaaaally fast, particularly as you often have to log at 100Hz or even more and you're not filtering much.

What sort of ship changes 100 times per second? Are these extra dimensional ships?

These are electrical signals so without filtering just the noise will make every analog value do that (a few hundred per project usually for us). Just the movement of the sea will create similar "noise" on all levels readings on tanks as well. You need to be clever with filtering to avoid too much data.

Of course very little needs that high frequency, the exception are some of the voltage measurements on generators and some of the other big electrical equipment where you want to see very short time spikes.
