The device works as follows.

Pre switch (not shown) on the counter 43 of block 6 is set to the appropriate position, for example, in the fifth (cycle of five pseudo-random sequences of 160 letters).

Turn on the power. The counters and distributors are set to their original position, the trigger 16 of the driver 2 is set to the zero position (Fig. 11a): the trigger 20

switch 3 and trigger 30 of block 4 - to the second position (zero on the first output, and one potential on the second), on the display 58 of the remote control 9 a number is lit

2, indicating the presentation of two control characters (letters) to the student.

Clock pulses from the output of the generator 12 of the driver 2 through the prohibition element 14, to the control input of which zero potential is supplied from the output of the OR element 17, are received (Fig. 116) to the input of the generator 13 through the prohibition element 15, yn. the equal input of which is fed zero potential from the output of the element OR 25 switch 3, and through the element 31 of the prohibition of block 4, to the control input of which the zero potential is fed from the output of the trigger

30, to the input of the distributor 26 (FIG. 11c). At the outputs of generator 13,

0 binary code patterns that are applied to the inputs of the elements E 50 and Or 55 of block B, and to the inputs of the decoder 10 of block 1.

Upon receipt of each clock pulse, a single potential moves along the outputs of the distributor 26 of block 4, being applied alternately to the inputs of the corresponding elements AND 28.

With the appearance of the generator outputs

0 13 units 1111Г at the output of the element And 50 of the block 8 in accordance with the unit potential (fig. 11 g), which through the inhibit53, has a zero potential at the control input from the first output

5 switch 3, enters the entrance of the banner 56 Presentation, illuminating the latter.

At the same time, a pulse from the output of the element 53 will transfer the trigger 16 of the driver 2 (Fig. 11a), the unit potential from whose output through the OR element 17 goes to the control input of the element 14, stopping the supply of clock pulses from the generator 12 (Fig. 116, c).

5 When pressing the button 60 Starting the console 9, the impulse from its output (Fig. 11d) will transfer the triggers 16 and 30 to the second position. The zero potential from the output of the trigger 16 (Fig. 11a), fed through the element OR 17 to

0, the control input of the element 14 will provide the clock pulses (Fig. 116) to the input of the generator 13. The zero potential from the second output of the trigger 30, applied to the control input of the element 32, will provide

5 supply of clock pulses to the input of the distributor 27 (FIG. Lie), and the unit potential from the first output of the trigger 30, applied to the control input of the element

31, will block the entrance of the distributor 26 (Fig. 11c).

Clock pulses from the output of the element 14 are fed to the input of the delay element 18, to the input of the generator 13, providing a change of the binary combination and the transparency 56 of the console 9, and to the input of the distributor 27 of block 4, moving the unit potential at the outputs of the latter.

When an element 28 appears at the second (informational) input, at the first input of which there is a single potential from the output of the distributor 26, a single potential at its output is a pulse (Fig. 11g) that goes through the element OR 33 to the input of the counter 19 of the switch 3, produced a unit reading, and to a separate input of the one-shot 34 block 5, causing a pulse with a duration of 1 s at its output (Fig. 11h).

The pulse from the output to the control input of the element 14 will stop the binary code combination (Fig. 115) at the outputs of the generator 13, which is applied to the inputs of the decoder 10 of block 1 and to the input of the block former 29.

The code of the letters from the output of the decoder 10 is fed to the information inputs of the indicator 11. A pulse from the output of the one-shot 34 (Fig. From) fed to the ignition input of the indicator 11 will ensure that the reference sign is displayed for 1 s.

At the end of the pulse from the output of the one-shot 34 at the output of the shaper 29 of the block 4, a short pulse is received (Fig. 11i), which returns the distributor 27 to its initial state. At the same time, blocking is removed from the generator 12 and the clock pulses (Fig. 116) through the element 14 are fed to the input of the generator 13 and through the elements 15 and 32 of the prohibition on the input of the distributor 27 (Fig. Not).

The appearance of a single potential at the second input of the AND 23 element from the output of the distributor 27 (Fig. 11 g) will ensure the submission of the second test letter to the subject.

At the second output of counter 19, a single potential is applied to the first input of the element AND 21. Thus, at the second input of the element 21 there is a single potential from the second output of the trigger 20, then the output potential of the element OR 25 shows a single potential that is applied to the first input element And 23, preparing the circuit to control the duration of the presentation of characters, and to the control inputs of the elements 15 of the imaging unit 2 and 53 of block 8, blocking the outputs of the latter.

When a single impulse appears at the output of an element 50, (fig. 11 g), the latter

enters the input element And 51 and through the element 54 of the prohibition on the input element And 23 switch 3. The pulse from the output element And 23 is fed to the input element 39

delays of block B and to the information input of register 36. The pulse from the output of element 39 will pass through the element OR 37 to the control (clock) input of register 36 and record the unit to its first digit

0 (Fig. 11 k).

The unit potential from the output of the first bit of register 36 will go to the control input of the key 35i. A clock pulse from the output of element 18 of generator 2 passes through element I 52 of block 8 to the second (informational) inputs of keys 35. Since the first (control) input of key 351 has a single potential, the pulse from its output (Fig. 11l) will pass to the input of the new vibrator 34 and launch the latter.

A single potential from the first output of the register 36 through the element OR 38 is applied to the input AND 51 of the block 8, preparing a circuit for the passage of pulses from the output of the element

5 and 50 at the inputs of the element 40 of the delay and counter 43 of block 6.

The pulse from the output of the oscillator 34 of block 5 (fig. 11z) through the element OR 17 is fed to the control input of the element

0 14, providing a double code from the output of the generator 13 through the decoder 10 to the indicator 11. A pulse from the output of the single-switch 34, applied to the control input of the indicator 11, will highlight the information

5 letter for 0.8 s.

At the end of the pulse from the output of the one-shot 34, the glow of the letter on the indicator 11 is briefly stopped, the prohibition element 14 is opened, since a single

0 pulse output element) OR 17 terminated.

From the output of the generator 12 enters the clock pulse, which through the element 14 is fed to the input of the generator 13, forming

5 at its output is the following code combination. At the output of the element OR 55 of block 8, a pulse appears that goes to the first input of element AND 52. The delayed pulse from the output of element 18 (the delay time is equal to the duration of the pulse) applied to the second input of element AND 52 through the key 35i of block 5 will pass to the input of the one-shot 34, running the latter.

The following information sign (letter), etc., is presented to the subject. The test subject appearing among the information letters is a check mark in the memory.

After the presentation of 32 characters at the output of the element And 50 of the block 8, a pulse is observed.

which, through the element AND 51, enters the input of the counter 43 of the block 6. fixing the presentation of the first sequence and the input of the delayed AO element, ensuring the appearance at its outputs of a sequence of two pulses that through the OR 42 element arrives at the input of the forward count of the reversible counter 44 blocks 7.

Fixing the fifth sequence will provide a pulse at the output of the counter 44, which will illuminate the transparency 57 Response at the console 9, and fed through the OR 17 element to the control input of the element 14, will stop the delivery of clock pulses to the generator 13.

The test number of counted control letters held in the memory, one by one using the button 61 The set (single pulse shaper) feeds the countdown input of the reversible counter 44, and at the end of the input presses the button 62 Result.

If the subject correctly determined the number of control letters in the cycle, then at the output of the element 49 of block 7 there is a pulse which, through the element OR 37 of the block 5, goes to the shift input of the register 36, converts the unit to the second output, and to the converting input of the counter 43 of the block b . returning the latter to its original state. The time for presentation of information signs in the next cycle will be 0.4 s. With correct answers, the presentation time is reduced by gradations: 0.2: 0.1; 0.05 s,

If the subject correctly identified the control characters in the sequence at the time of presentation of the 0.05 s sign, then the correct response impulse from the output of block 7 will go to the input of the element OR 37 and move the unit to the last output of register 36, the unit potential from the last output of register 36 goes to trigger input 20 of switch 3, transferring it to the first position (unit potential at the first output), and AND 24, the pulse from which output will return counter 19 to the initial position, to the second input of the element. A zero potential is supplied to the control input of the element 41 of the block 6 from the second output of the trigger 20, and to the control inputs of the elements 15 and 53 is a zero potential from the output of the OR 25 switch 3.

Clock pulses from the output of the generator 12 are fed through element 14 to the generator 13 and the distributor 26. From the output of the generator 13, the binary combination enters the decoder 10, the elements AND 50 and OR 55. There are five 11111 units in the binary code sequence

At the same time, the element 50 and Wits pulse, the transparency 56 and the indicator 59 3 light up, i.e., in the next cycle, the subject must distinguish three different control

letters, which he will then have to reveal in the presented information sequence.

If the subject incorrectly determined the number of control letters given in

In the loop, the information from the output of the counter 44, attached to the decoder 45, when the control pulse arrives at its input from the output of the button 62, will indicate on the indicator 46 the number of errors.
