root mean square (plural root mean squares)
(mathematics, of a set of numbers or values) The square root of the arithmetic mean of the squares.
As a result, voltage for alternating current almost never refers to the voltage at a particular instant, but instead is the root mean square (RMS) voltage, which is a way of defining an effective voltage when calculating power (RMS voltage × RMS current). Source: Internet
Jitter can be quantified in the same terms as all time-varying signals, e.g., root mean square (RMS), or peak-to-peak displacement. Source: Internet
Estimating the parameters The most common choice in optimization of parameters is the root mean square criterion which is also called the autocorrelation criterion. Source: Internet
If rather the fields are described in terms of their root mean square (rms) values (which are each smaller by the factor ), then the correct average power flow is obtained without multiplication by 1/2. Source: Internet
Mathematically the radius of gyration is the root mean square distance of the object's parts from either its center of mass or a given axis, depending on the relevant application. Source: Internet
One property of root mean square voltages and currents is that they produce the same heating effect as direct current in a given resistance. Source: Internet
