The RMS xrms is a measure of the average energy of the signal in a time slot on according to formula (2) can be obtained before and after the time t0 of the two-stage energy ratio.
Effective value of xRMS is the signal in a time slot on the average energy of the metric, so according to Eq. (2) can be in t0 moment before and after the two energy ratio.
XRMS is a signal of valid values in a time measure of the average energy of, in accordance with (2) are in the t0 moment of energy than both before and after.
