Description

The invention relates to computing and can be used in static modeling.

The purpose of the invention is to show the accuracy of reproducing a random process by taking into account and reproducing its Markov properties.

The drawing shows the structural scheme of the proposed generator.

The generator contains a source of I-start signal, a generator of linearly varying voltage, a source of noise 3, keys 4, functional converters 5, integrators 6, comparison circuit 7, keys 8, counters 9, comparators 10, adder 11, memory blocks 12 , the 13 delay elements.

The generator works as follows.

The device is started by a signal from source 1 output. The generator 2 and source 3 are turned on simultaneously, keys 8 are locked, and accumulator 11 is reset, since counter 9 (operates at the first signal received at its input, from source 1, and counters 9 - 9 | do not work, the signal from 1 generator 2 through an open signal from counter 9, key 4 is sent only to the input of the functional converter 5,.} The formation of a random number with a given distribution law by blocks 5,6,, 7, and 3 is started.

In fact, the growing voltage from the generator, -, of torus 2 is transformed into a functional1) by its own converter 5 | is integrated by the integrator 6, and the first input of the comparison circuit 7 enters the increase of its voltage. At the second input of circuit 7, a random number is received from source 3. At the time when the voltages are equal, the signal opening key 8 is given to the two inputs of circuit 7 of comparison BE.1. The signal from generator 2, proportional to the designation of the first generated Markov process via key B, receives the fia input of comparator 10 (and the first input of adder 11. At the same time, the signal from circuit 7, comparing the set; ze-1 to the starting state of the IGtegra mountains 6, through Element 1 3 (delays counter H, and closes key 4, in the chalisimos of HZ from all the reasons of the displaced K on the command) on the signal noiiB UK - i sspl on one ei o go out, then i- Of iiC M and asch by. eiine

to the control plates of the functional-Fioro converter 5, corresponding to the output of the memory block 12 approximating the conditional density of probability. The next beat begins.

generator work. The signal from source 1 reads the first value of the formed random process from the output of adder 11, and it resets O to zero. At the same time, keys 8 are closed, the readings of all counters 9 increase by one, and blocks 2 and 3 are started.

In the second cycle, counters 9 and 9 5 open the keys 4, and that ensures the formation of the values of two Markov processes. Adder 11 receives two new ones. A corresponding adjustment is made to the 20 settings of the memory blocks 12 and a new cycle of operation of the generator begins. At the output of the generator, the second value of the implementation of the two processes appears. Thus, the realization of a random Process of length K is formed and the formation of the next realization automatically begins.
