The Measurement of the Mean Square Value of Certain Random Signals†
O.L.R. Jacobs · Journal of Electronics and Control · 1960
Some practical methods of measuring the mean square value of a common class of random signals are analysed. It is shown that for averaging operations an integrator is more efficient than a low pass filter. The variance of estimates is given for certain simple cases when an integrator is used in conjunction with either a squaring device or a rectifier.
