Hi
I would like to ask what is the best approach if I have to compare two dc signals with a lot of fluctuations on them. I have already checked the frequency spectrum and I see no high frequency noise. However the signal fluctuates around +- 5% of the mean reference.
So, is it enough if I compare the mean values of these signals or any other digital filtering technique is better ?
