FIELD: electricity.
SUBSTANCE: digital-to-analogue noise generator comprises pseudo-random number generator as a source of initial digital noise; it is synchronised by the reference generator and loaded by a group of adjacent outputs to a set of identical controlled current generators, which outputs are jointed by a summing unit and the jointed second outputs are connected through a filter to output of the comparator; output buffer unit and converter of effective voltage value are also connected to the summing unit, at that the converter is connected to one input of the comparator, which second input, in its turn, is connected to the reference voltage clamp.
EFFECT: improved accuracy in reproduction of static noise characteristics, expansion of its energy spectrum.
