Hi,
I'm somewhat weak on filtering theory.
We're having a discussion in the office about using a moving average filter versus a low pass filter in RSLogix for an I/O input measuring pH.
If I run tests in the PLC I can see some of the differences in the results, but I don't know where/how to start when it comes to the language/math of comparing the two methods.
I also don't understand where one would use moving averages or low/high/band pass filters in an industrial application.
Thank you,
Chris
