The invention relates to computing technology and can be used to generate random events with a given distribution law occurring in complex systems in a statistical study of the mathematical models of these systems on an electronic computer in order to determine quality characteristics, such as reliability indicators.

Devices are known for generating streams of random events distributed in space. With this law, this law represents the numbers corresponding to the numbers of the events generated, or the time intervals between pulses and containing the dial field, the source of the primary flow, logic elements 1 ..

However, these devices have one output and do not allow to form one of the m signals.

The closest technical solution to the present invention is a probabilistic (l, k) pole containing a source, a primary stream of pulses, a one-shot, element I, a counter, a decoder, a switch, a block of flip-flops 2,

This device allows receiving; a signal at one of the m outputs, but does not allow receiving signals at k from m outputs.

The purpose of the invention is the extension of the functionality of a probabilistic (k, m) -port grid due to the formation of signals at the m outputs of the probabilistic (k, t) -bag with k 1,2, ..., m.

To achieve this goal, in a probabilistic (k, m) -polar, containing a decoder, a random flow of pulses, the output of which is connected to the first input of an And element, the second input of which is connected to the output of a single vibrator, whose input is t) -polar, introduced the memory register and random number generator, the input of which is connected to the output of the element I, the group of outputs of the random number generator through

The decoder is connected to a group of memory register inputs, respectively, the input of which is combined with the input of the one-shot, and the m outputs of the memory register are the m outputs of the probabilistic (k, t) -port. On the line e is a block diagram of a probabilistic (k, ro) -port. The probability (k, t) polarizer contains a generator 1 of a random stream of pulses, a one-shot 2, an AND 3 element, whose inputs are connected to the outputs of the generator 1 and one-to-switch 2, and the output to the input of a generator of 4 random numbers, the outputs of which through de-equiprator 5 connected to the inputs of the memory register 6, the output of which are the outputs of a probability {k, t) -portr, the input of which is connected to the input of the one-oscillator 2 and to the input of the register b of the memory; . The interrogation signal resets the memory register b to the initial state and starts the one-shot 2, which opens AND 3 for a predetermined time t. During this time, the pulses from the generator 1 of a random stream of pulses arrive at the input of the generator 4 of random numbers and start it. At the same time, with the arrival of each triggering pulse, a random number is generated at the output of the generator 4, for example, in a binary code that goes to the inputs of the decoder. This number is decrypted and on the corresponding bus from the output of the decoder 5 reverses the 6 register trigger, the number of which corresponds to the number of the decoder input bus 5 The law of distribution of the number of simultaneously occurring elementary events (the number of random impulses that passed through the element I 3) is given, based on a priori known intensity n rvichnogo stream of random pulses X biruyuschego tup for this time interval t A. For a Poisson flow, the probability of k points (events occurring) on a segment of length u, t is determined by the well-known Poisson formula). Elementary events (passing through an AND 3 pulse) are generated by the triggering of a random number generator 4, in which the distribution law is specified as the probabilities of each of these events. So, during one operation cycle of the device (the interval between neighboring polling pulses), so many elementary events, how many impulses pass through the element 3 for the start of generator 4. These events are recorded in memory register 6, i.e. at the end of the cycle the triggers with numbers will be knocked over, respectively elementary events. With the arrival of the next interrogation pulse, the operation cycle is repeated.
