Description

(54) GENERATOR OF FLOWS OF RANDOM EVENTS

tane (a positive outcome of a random test corresponds to the generation of a pulse at the output of the coincidence circuit, opened by a potential input at the moment a pulse signal from block 1 arrives at its second input) a clock pulse generator 3, generating clock pulses and thereby setting the duration of a random test; trigger 4, connected at the counting input with generator 3 (controls random testing by detecting potential to match the circuit of block 2, and also controls the formation of the output signal of the random event flow generator), register 5, the single set inputs of which are connected to the outputs of block 2 And elements (remembers the outcomes of random testing in each of the coincidence schemes of block 2); block 6 of elements And, containing coincidence circuits having two direct inputs and inverse inputs (allocates the most senior of those bits of register 5 into which units were written during random testing, and thus generates the output signal of the random event streams generator); generator polling circuit 7 connected to generator 3 and register 5 (serves to start generator 3 and update register 5), interlock circuit 8 connected to zero output of trigger 4 (intended to disable generator 3).

The generation of random event streams works as follows.

The signal entering the generator polling circuit 7 zeroes the register 5 and starts the clock 3.

The first pulse, given by the clock pulse generator 3 to the counting input of the trigger 4, triggers the unit to one state and opens the coincidence circuitry of the unit 2 for the potential inputs. The pulses of block 2 are fed to single setting inputs of register bits 5. A second pulse, driven by generator 3, sets trigger 4 to the zero state. At the same time, the passage of pulses through the coincidence circuits contained in block 2 is prohibited, the second direct inputs of the coincidence circuit of block 6 are opened and the clock pulse generator 3 is turned off through the block B circuit. Register bits 5 are numbered one to N discharged, and boldly younger. Block 6 allocates the most significant bit of those bits of register 5 into which units were recorded during random testing by issuing a prohibitory signal from the corresponding coincidence circuit of block 6 elements AND to the inverter inputs of all the coincidence circuits of the same block connected to the least significant bits O .. master 5

The potential at the output of one of the coincidence circuits of block 6 corresponds to the appearance of one of the values of a random variable distributed in space. After the next polling signal arrives, the process repeats.

A random variable obtained at the generator output, distributed in space in accordance with a given law, can be easily transformed into a random time interval, a number, etc.

The switchboard can operate in a continuous flow of random events (for this, polling circuit 7 must be connected to the zero output of trigger 4 through a delay element), and also random variables distributed according to a given law can be added to the request.
