The paper describes the High Precision Stochastic Digital Measurement Method that takes the advantage of fast electronic components in order to simplify and cut the costs of hardware used for electric energy measurements, whereas reducing the number of error sources in instruments. It is shown that the key element in this system is the fast Flash ADC. For every new bit of Flash ADC resolution, its hardware is consequently doubled in complexity, as the standard price for that additional new bit of resolution. A definition and a solution for the fundamental problem of optimal (maximum) increase of Stochastic Flash ADC precision and equivalent technology speed at the standard price of hardware doubling are given. Resolution increase from two to three bits is found to be optimal, giving the precision increase of three times and the speed increase of nine times, compared to the two-bit version. All other cases give precision increase of around two times and 5-6 times increase of the equival...ent technology speed.
