# Root mean square interpretation

i am working in control theory problem where at the end i get error signals and i am trying to classify this signals, i choosed easy implementation because of limitaion of microcontroller which i will program later. the easiiest way was to calculate the Root mean square of the random signals, and average (mean) by taking 10 samples from signals. as I remember from my old study mean calculation is the same as measuring the voltage by DC volt-meter and i found that RMS has some interepretaion in wikipedia regaerding power.

my question is if i have two rms values for two signals i.e. rms1 > rms2 what can i intrepret this?
