the triggers 46 and 47, the element is NOT 48, the element OR 49, the generator of 50 pulses, the element And 51, the elements And 52 and 53, the element NOT 54, the element. And 55 „

The device works as follows.

They turn on the power. At that, the generators 11 and 12 random numbers of the block 1 are started. When ready, the subject briefly presses. One of the buttons on the switch 21 of the remote control 4 "Depending on which button is pressed, the list presented to the subject will be Two, three and five three-digit numbers, respectively. The order of the test's actions is determined by the instruction Depending on the position of the 24 Mode switch, the list is presented to the subject either for a certain time, which is set in the waiting multivibrator 40 of the block 5 (Fig. 2), or for the entire duration of this experiment sample.

Pressing one of the buttons of the switch 21 on the corresponding input of the register 38 of the block 5 sets a high potential (1). At the time of holding the button of the switch .21 1 (FIGURE 4a) is also set at the output of the element 37 OR and is fed to the input C of the register records 38 writing to the register 38 the corresponding code goes to the starting input of the standby multivibrator 40, to the inputs R of the installation in O of the trigger 47 of the block 5, the counters 25 --28 of the block 7, preparing them for operation, as well as the input of the register 13 of the block 2, with the last of the first generator 11 random numbers are recorded in five three-digit binary-decimal random numbers that make up a list of

When lowering the switch button 21 on the falling edge of a single pulse (Fig. 4a), the waiting multivibrator 40 of the block 5 generates a pulse with an adjustable duration equal to the list indication time.

The code from the output of the register 38 is fed to the first inputs of the node elements And 39, acting as keys. Depending on switch position30

pulse from the standby multivibrator 40o Accordingly, the code from the outputs of the elements And 39 is given to the indication input of the decoder 14 (FIG. 4b) and depending on the number of the pressed button of the switch 21, includes an indication of two, three, or five three-decade decimal numbers indicator 16, presented to the learner a list of

The pulse from the standby multivibrator 40 is fed to the recording input of the trigger 41, at the information input of which a high potential is constantly present. At the falling edge of the pulse at the output of the trigger 41 there is a high potential that will allow the passage of clock pulses from the generator 42 through the element I 44 o

In addition, the pulse from the output of the standby multivibrator 40 is fed to the first input of the element OR 49, to the second input of which an inverted signal of the generator 42 is fed through the element AND 44 and the element NOT 48. Thus, the output of the element OR 49, which is the output of block 5 control, a signal (FIG. 4d) arrives at the input to the record of a twelve-bit bottom register 18; In this case, a binary-decimal random number from the generator 12 is written to the register 18

At the same time, the code from the output of the register 38 of the block 5 of the form 100, 010 or 001 - depending on the series number (from the number of the pressed switch button 21) is sent to the address input of the multiplexer 43 of the block 5, while one of the binary numbers will pass to its output: 6, 9 or 15 and on a four-bit bus will arrive at the input of the counter 20 of block 3, giving it the counting coefficient (Fig 4).

The signal from the output of the element OR 49 is fed to the first input of the element AND 51, allowing the passage of pulses from the output of the generator 50 to the output of the control unit 5 (fig. 4). The resulting burst of pulses with an unstable tracking frequency (t, e. enters the input of the meter 20, with

The mode on the second inputs of this element will be formed at its output.

And 39 will either be permanently with a random four-digit code, there will be a high switching potential that arrives at the address input, or only for the time of the pro 19, part of the 12-bit inputs

pulse from the standby multivibrator 40o Accordingly, the code from the outputs of the elements And 39 is given to the indication input of the decoder 14 (FIG. 4b) and depending on the number of the pressed button of the switch 21, turns on the indication of two, three or five three-digit decimal numbers on the indicator 16, presented to the student a list of

The pulse from the standby multivibrator 40 is fed to the recording input of the trigger 41, at the information input of which a high potential is constantly present. At the falling edge of the pulse at the output of the trigger 41 there is a high potential that will allow the passage of clock pulses from the generator 42 through the element I 44 o

In addition, the pulse from the output of the standby multivibrator 40 is fed to the first input of the element OR 49, to the second input of which an inverted signal of the generator 42 is fed through the element AND 44 and the element NOT 48. Thus, the output of the element OR 49, which is the output of block 5 A control signal appears (FIG. 4d), a twelve-thirth bottom register 18 input to the recording. In this case, a binary-decimal random number from the generator 12 random number is written to the register 18

At the same time, the code from the output of the register 38 of the block 5 of the form 100, 010 or 001 - depending on the series number (from the number of the pressed button of the switch 21) is sent to the address input of the multiplexer 43 of the block 5, while one of the binary numbers will pass to its output: 6, 9 or 15 and on a four-bit bus will arrive at the input of the counter 20 of block 3, giving it a counting coefficient (FIG. 4).

The signal from the output of the element OR 49 is fed to the first input of the element AND 51, allowing the passage of pulses from the output of the generator 50 to the output of the control unit 5 (fig. 4). The resulting burst of pulses with an unstable tracking frequency (t, e. enters the input of the meter 20, with

8, 14, 15 are connected to the 12-bit output of register 3o. Switch 19, depending on the address code received at the input, passes either an accidental 3-bit binary-ten number or one of the numbers stored in the output to register 13o The described above connection-, the inputs of the switch 19, is due to the necessity of uniformly selecting numbers from the list in order to present them to the examinee among random numbers for identification. When connecting to an average of six presented numbers, four numbers will be random, and two numbers from a list (2, 3, or 5 three-digit binary-decimal numbers) are about

At time t, (Fig. 4), the presentation of numbers from the list is over (for mode 1 - switch 24 Mode in position 1), the final code is set at the address input of switch 19, and the output will be either a random number or list, which, in turn, goes to the input of the decoder 15 and to the input B of block 6 of the comparison.

At the same time, the signal from the output of the element OR 49 of the control unit 5 is fed to the recording input of the D-flip-flop 46, the high potential from the output of which permits the passage of the Signal from the generator 42 through the elements 44 and 45 to the output of the control unit 5. The high potential of the drive unit 5 is fed to the input of the indication of the decoder 15, while on the indicator 17 a 3-digit decimal number is displayed,

The input of block 6 comparison with the output of register 13 receives codes 2, 3 or 5 numbers of the list (depending on the number of the pressed button of the switch 21 Seri)

If the number at the output of the switch 19 (at the input B of the comparison unit 6) is at least one of the list, then the output of the comparison unit 6 will form a high potential that will go to the input of the control unit 5
