The noise generator 1 generates noisewhere n is the dimension of the field of values of a random noise, Sn- number of outputs signal noise in each dimension, which simultaneously acts on n blocks of digital filters 2, are controlled from the control unit 7 signals. Due to the fact that each of the s-digital filter consists of a delay element, a multiplier unit and an adder, the output of the adder connected to the input of the delay element, the output of which appear detained on the sampling interval timing, and a variable multiplier multiplier device provides the operator with control unit 7, due to randomization (under the randomization refers to the random nature of choice of many alternatives according to some set of discrete probability distribution) of the generated random field at the output of each s digital filters 2-1 succeed si is Nala that are computed for each i-component, j-components as follows:

where ν - the number of coordinates of the field;

The control unit 7 controls the random number generator 6, and he in turn controls the operation of multiplexer 4. Outputs of the serial adders 3 signalsproceed to the appropriate multiplexers 4, are managed by using a random number generator 6 signals. Using signalsreceived from the random number generator 6, each multiplexer 4 selects and the all the input s of sequences, coming from the serial adders 3, only one λnsequence.

From outputs of respective multiplexers signals λnreceived by the device of visual output 5.

For synchronous operation is used by the master oscillator 7-3 in the control unit 7. The outputs of the master oscillator 7-3 associated with all registers 7-1 control unit 7, with blocks of serial adders 3, with the random number generator 6.

Each digital filter 2-1 from a block of digital filters 2, on each successive adder 3-1 from a block of consecutive adders 3 in the control unit 7 has a control pair, consisting of a register 7-1 and 7-2 encoder. In addition, the control unit 7 has two control pairs, consisting of a register 7-1 and 7-2 encoder to control the operation of the noise generator 1 and the random number generator 6.
