Description

The invention relates to a decisive technique and can be used to model random numbers with a uniform distribution.

The aim of the invention is to expand the field of application of the generator by obtaining a uniform distribution.

The drawing shows a block diagram of the generator.

The generator contains a source of constant voltage 1, input Poll 2, keys 3-5, multivibrator 6, trigger 7, delay element 8, counters 9 and 10, elements OR 11 and output 12.

The generator works as follows.

In the initial state at the output of the waiting multivibrator 6, the voltage is absent, the switch 3 is closed. At one of the outputs (for example, connected to the control input of the key 4) of the trigger 7 there is a high potential, and on the other (connected to the control input of the switch 5) there is no voltage. Therefore, by assumption, key 4 is open, and key 5 is closed. A voltage is applied to the input of the key 3 from the power source 1.

The impulse received from the bus 2, starts the waiting multivibrator 6 and passes to the input of the element 8 delay. From the output of the multivibrator 6 for a short period of time (open) voltage is applied to the control input of the switch 3. This period of time should be sufficient to generate pulses on the discharge output counters 9 or 10. The power supply voltage from source 1 through public switches 3 and 4 enters the power bus of the counter 9. The triggers of the counter 9 spontaneously set to state 1 or 0 for the period of the open position of the key 3. With the end of the specified period, the voltage from the control input of the key 3 is removed - the key 3 voltage is removed from the power bar of the meter 9. Thus, the discharge

the outputs of the counter 9 through the corresponding elements OR 11 to the output buses 12 receive pulses of a parallel code - on the output wounds 12

we have some arbitrary number. At the same time, the pulse delayed by the delay element 8 arrives at the counting input of the trigger 7 and overturns it. The voltage is removed from the control input of the key 4 and a high potential is applied to the control input of the key 5. The key 4 is locked, and the key 5 is opened.

With the arrival of a new impulse on pulse start 2, the operation of the random number sensor repeats in the same way (instead of counter 9 and key 4, counter 10 and key 5 are interchanged).
