Description

This invention relates to modeling random processes and is intended to generate random impulse streams with a linearly decreasing distribution density of durations.

A random pulse generator with a linearly increasing duration density distribution is known, comprising a random pulse generator with a uniform distribution of durations with three outputs, the first of which is connected to one input of a coincidence circuit, the second input of which is connected to one of the inputs of a probabilistic binary element, the output of the coincidence circuit is connected with one of the inputs of the circuit assembly.

The purpose of the invention is to increase the reliability of the generator.

For this, the second and third outputs of the random pulse generator with a uniformly first distribution of durations are connected via an additionally introduced coincidence circuit, the control input of which is connected to the second output of the probability binary element and connected to the second input of the assembly circuit.

The second and third outputs of the random-tone generator with a uniform distribution of durations can be connected to the input of the newly introduced coincidence circuit.

through the finally inserted build scheme. In the drawing, the presentation of 1a block diagram of the proposed generator.

The generator 1 random pulses with a uniform distribution of durations has three outputs, one of which is connected to one input of the circuit 2 coincidence. The second input of the coincidence circuit is connected to one of the inputs of the probabilistic binary element 3. The output of circuit 2 is connected to one of the inputs of circuit 4 of the assembly. The second and third outputs of the generator 1 are connected to the second input of the assembly circuit 4 through the coincidence circuit 5, the control input of which is connected to the second output of the element 3. The assembly 6 of the assembly 6 and the assembly 5 of the assembly is connected to the assembly 6.

Generator 1 in each clock cycle but gives three channels fixed on the front and

rear fronts n: pulses with a uniform fi (t) distribution of durations. VertiHHTHbni binary element 3 at the beginning of each clock cycle is set to one state with a certain probability q or

in the zero state with probability 1-q and, respectively, connects to output 7 the output of circuit 2 or 5. From the output of circuit 2, random emulsions with uniform F (/) distribution of durations arrive. From the output of circuit 5, an impulse arrives, which is longer in duration from two input pulses. The larger pulse algorithm corresponds to the operation of multiplying the distribution functions of the original random pulses with a uniform Fj {i} distribution of durations. At the output of the coincidence circuit 5, we obtain a random stream with a distribution function of durations F, {t) Fl (t}.

Uchntyva that output 7 receives (1-1) - part of the pulses from the output of circuit 5 of coincidence and q - part of pulses from the output of circuit 2 of coincidence, for the distribution function of the output random flow is true

F (qF, (t) + (l + q) Fl (t),

which corresponds to LNPI age, its density of distribution.

If we exclude assembly circuit 6, it is possible to obtain at the output of circuit 5 a coincidence stream with a distribution function

F, (f) 2F, (f) + Fl (f).

In this case, the distribution function of the output random flow can be expressed through the operation of stochastic superpositions

F (f) qF, (+ (1+ q) 2f, (t) - Fl (i).

which corresponds to a linearly decreasing distribution density.
