SU373718A1 - GENERATOR OF RANDOM PROCESSES - Google Patents

Description

The invention relates to the field of computing and can be used in solving problems of statistical modeling on computers.

Known sources of random processes, containing a group of independently operating pulse generators, logical and storage elements, make it possible to solve the problem of forming a generalized telegraph signal with certain statistical characteristics. If there is a need for a large number of generalized telegraph sigals, these known solutions lead to a significant increase in equipment.

The aim of the invention is to create a device that allows synthesis of FiaTb by relatively simple means of a gamma of binary random processes (a multidimensional process).

The goal is achieved by the fact that the pulse generator in each channel is connected to the first input of the OR circuit, the second input of which is connected to the output of the differentiating chain, the output of the OR circuit is connected to the counting input of the trigger, the output of which is connected to the output terminal of its channel chain of the previous channel, the output of the trigger of the first channel is connected to the input of the differentiated chain of the n-th channel.

A block diagram of a device for generating a three-dimensional random process is depicted.

in the drawing.

A group of identical pulse generators / through logic circuits OR 2 is connected to the counting inputs of triggers 3. The triggers are sequentially connected to a ring scaling circuit through differential plots 4 and logic circuits 2. On single outputs 5 triggers, a gamma of generalized telegraph signals is formed, the number of which is determined by the number channels from adements /,

2, 3, 4.

The scheme works as follows. The next signal from one of the pulse generators / through logic circuit 2 changes the state of the corresponding trigger 3

on the opposite. If this trigger was in the zero state, then with the signal, it will be tilted to a single unit. If this trigger was in a single state, then with the arrival of the signal on the account

the input will be tilted to the zero state, the II will pass through the ring through the elements 4 2 of the next channel a transfer pulse.

If all channels are identical, then the generated binary random processes on the outputs, 5 will be statistically equivalent.

A pack like no other channel has the “advantages” over the others.

The most important characteristics of the generated random processes are the average pulse rates X, Xz,
