Description

The invention relates to computing and can be used to simulate results in tests in a random event circuit.

The purpose of the invention is to expand the functionality of the device by reproducing the full group of incompatible events.

Figure 1 shows the block diagram of the device; figure 2 is a diagram of a composing floor; FIG. 3 is a diagram of the registration block; figure 4 is a temporary diagram of the operation of the device.

The device contains a generator of 1 clock pulses, a group of registers 2 shift, a group of typed fields 3, a sensor 4 random time intervals, a dial-up field 5, a group of elements 6I, a block 7 for recording the number of random events, a counter 8.

The dial pad 5 contains switches 9 and elements 10 OR.

Block 7 registration contains the elements 11 And the counters 12.

The device works as follows.

A typing field 5 sets the complete group of incompatible events at the first inputs of elements 6I. The typed fields 3 set the probabilities of these events.

When the generator of the I clock pulses is turned on, the pulses are fed to the inputs of the shift of the shift registers 2,

under the action of which in registers 2 shift codes of numbers circulate.

At the outputs of the first digits of registers 2 of the shift, direct impulses of duration Ij T and a period of T pT are formed (fig.Ab, 4c, 4d), which arrive at the corresponding first inputs of block 7 of registration and further to the first inputs of the group Elements 11, V .., Itz, Sensor 4 random time intervals are synchronized to the leading edges of rectangular pulses from the first output of the first shift register 2 and interrogated by pulses with an equalization period equal to T (FIG. 4e). After the next polling pulse from the output of sensor 4, after a random period of time distributed with a uniform density on the time interval T, a pulse appears (Fig. 4e), which goes to the second inputs of the registration unit 7 and then to the second inputs of the element group

Commerce And 11 ..., 11. The appearance of a pulse at the output of the sensor coincides in time with a rectangular impulse arriving at the first input of one and the Elements 11. Consequently, at the output of this element And 11, i.e. an i-oM (i 1,2, ..., k) output of the device appears a pulse (Fig. 4e), which characterizes the onset of the corresponding event A; with probability P; {1 to). The probability of the pulse at the 1st (1 1, k) output of the device is generally equal to

P T i i - J tG f n

about . Thus, the probabilities of the occurrence of events A,, correspond to the static probabilities of the occurrence of events

11 pulses (FIG. 4e) from the output of sensor 4 in random intervals, determining the implementation of the test, are fed to the input of the counter 8 of the total number of tests, and the pulses from the outputs of the MP, ..., 11 elements (FIG. 4G, 3, K) , determining the occurrence of corresponding events, arrive at the inputs of the corresponding counters of the 12th number of tests with a favorable outcome.

The readings of the counters 12 ,, ..., 12 to the counter 8 readings limit the values of the static values of the occurrence of events A, A2, ... ..., A, which form a complete group of incompatible events.
