5 Block 10 has a decoder and an indicator similar to block 6.

The device works as follows.

Turn on the power. Counter 26, registers 3 and 4, valve 9 are reset, and triggers 47.71 and 72 are set to zero. With the help of button 41 (without arrietir) of unit 5, a test program is compiled, for example, the numbers

5 in sequence: first 01 green: second 24 red; third 02 green; the fourth 23 is red, etc., the forty-seventh is 24 green, the forty-eighth is 01 red, the forty-ninth is 25 green.

0 When button 511 of block 5 is pressed, a single impulse from its output is fed to the corresponding input of the encoder 42, causing the appearance at its outputs of a combination corresponding to the code number 01. At the same time, this pulse through the OR element 51 is fed to the control input of the indicator of unit 10 and input V2 of register 3, translated the latter into parallel recording mode, and after passing through delay element 48, enters input C2 of register 3, ensuring parallel recording of the formalized binary number from the output of the encoder to register 3. On the indicator block 10 and 00 is illuminated, signaling his

5 being in the initial state.

The pulse from the output of the element 48, through the information input of the element 44 of the prohibition, to the control input of which the potential of the element 0 is output

0 14, and the element OR 52, is fed to the input of the generator 43, causing at its output the appearance of a series of eight clock pulses, which through the prohibition element 45, to the control input of which from the output of the element

5 OR 53 is applied to zero potential, fed to the input Ci of register 3, shifting the code combination from 1 to 8 bits (the last output of the group) to 9 to 16 bits (the penultimate output of the group). Binary combination of a number from the output of the penultimate group

register 3 is fed to the inputs of the decoder unit 10, the output code of which is fed to the indicators. The number 00 is replaced by the number 01, confirming the correctness of the input of the first number.

The next press of the nponsi- button 4124 records and advances the register 3 of the binary combination, the code of which corresponds to the number 24, since on the indicator of block 10 the number 01 changes to the number 24. Further program input is done in a similar way.

When entering the last but one number of the program, after displaying the number 01 on the indicator of block 10, the unit potential is applied to the control input of the element 44 of the block 5, from the first bits of register 3 (the first output of the group).

Pressing button 4125 of the last program number will not change the light of the monitored number 01 on the indicator of block 10, warning you that the program has been entered.

To present the program in random order, it is copied to register 4. To do this, the subject presses button 33 of block 1. The pulse from its output, entering the second input of timer 11, sets the last to its original position, passes through element 32 and the element OR 29 and starts a single vibrator 25, a single pulse from the output of which throws the trigger 47 of block 5 into one state, is fed to the input of the imaging unit 46 and to the second input of the element 28 of block 1, ensuring the passage of pulses from the generator 24, through elements 28 and or 30, on ix One counter 26 translates the latter into a random state. At one of the outputs of the decoder 27, corresponding to the given state of the counter 26, when a pulse arrives at its control input from the output of the shaper 46 of block 5 (after the pulse ends from the output of the one-vibrator 25), the potential that flows to the corresponding input of the block 2 - to the inputs of the imaging unit 34 and the element 36. The pulse from the output of the element 36 through the block of elements OR is fed to the third group input of block 8 - the second inputs of the corresponding elements AND 62, to the third inputs of which, through the element OR 68, from the output of the trigger 47 blocks 5 and served unit capacity, and to the first inputs, the first group is propelling input unit 8 is supplied with binary combinations output register 3 groups.

The code combination from this random exit of the group (elements 62), through

elements OR 63 and prohibition elements 66, on the control inputs of which the zero potential is applied from the output of the element OR 15, goes to the information inputs of the register 5.

The rear edge of the pulse from the output of the single-vibrator 25 of block 1 causes the appearance of the shaper 46 of the block 5 of a short pulse, which is fed to the input Q V2 of the register 4, having transferred the latter to parallel recording mode, and the delay element 49 passes to the input C2 register 4, ensuring parallel recording of the code combination from the outputs of the case group 5 of register 3 to register 4.

A pulse from the output of element 49, fed through element OR 52 to the input of generator 43, causes the appearance at its output of a series of eight clock pulses, which through element I 50, to the second input of which a unit potential from the output of trigger 47 is fed, is fed to the input C1 register 4, moving the binary combination from 1–8 to 9–16 bits, and received through

5, element 31 of block 1 and element OR 29 at the input of the one-shot 25, triggers the last one, removing the unit potential from the input of the shaper 34 of block 2, causing a pulse at the output of the pulse, which turns trigger 35 into one, providing writing to register 4 next random number.

If a random signal is reintroduced at the same output of the cipher torus 27 of block 1, then through the element 37 of block 2, to the second input of which a unit potential from the output of the trigger 35 is passed, passes to the input of the element OR 39. An impulse from the output of the element OR 39 will shift the contents of the counter 26 by one bit. This movement will take place until an unused output of the decoder 27 is detected. The unit potential supplied through the element 38 of the block 2 to the control

5 input element 36, prevents re-reading the binary combination with the outputs of the polled groups of the register 3.

When code combinations appear at the outputs of the first group of register 4, the unit potential through the OR 15 element is fed to the R input of the trigger 47 of block 5, transferring the latter to the zero state and preventing the last binary combination from progressing

5 input element 31 of block 1, blocking the path of the trigger pulse to the input of the one-shot 25, to the control inputs of the elements 66 of block 8, and blocking the information inputs of the register 4 through the element OR 53 block 5 to the control input of the element 45,

blocking the output of the generator 43 to the register 3, to the input of the generator 70 of block 8, a short pulse from the output of which establishes (confirms) the initial state of the counter 12 and triggers 71 and 72 of the block 19 and through the element 20 prohibiting the input of the key 18, applying the ignition voltage (single potential) to the control inputs of the indicators 56 of block 6.

A single potential from the output of the key 18 starts the timer 11. The subject is presented with a scoreboard of two-digit luminous numbers placed in a random order, green from 01 to 25, red From 01 to 24 on indicators 56 of block 6. In accordance with a given test program - | The user finds the number 01 - green and presses the button 61 of the switch 7 below him. The impulse from its output allows the code combination from the corresponding group of outputs of the register A to pass through the elements 57 and OR 58 to the outputs of the switch 7. The code composition of this number is out The switches 7 are fed to the second group input of block 8 — the first inputs of elements AND 65. At the same time, the pulse from the output of button 61 through the element OR 60 starts the shaper 59, the pulse from the output of which is fed to the first input of the distributor 9, ensuring the appearance of a single output on its first output potential, which through block 13 elements OR enters the second inputs of elements H62i

At the same time, the polling pulse from the generator 59 output through the OR element 68 is fed to the third inputs of elements AND 62, and through element 67, the delay time of which is equal to the response time of the element OR 63, to the second inputs of elements 65 and having read the information from the outputs of the first register group 3 and the outputs of the group of register 4 corresponding to the pressed button 61 on the switch 7, to the corresponding inputs of the elements OR 54.

When the number of subjects to test is determined at the outputs of the EXCLUSIVE OR 64 elements, the zero potentials, at the output of the element OR 69 is zero, if the answer is incorrect (the number is determined) at the outputs of elements 64, the potential potency at the output of the element OR 69 is the single impulse on the counting input of the counter 12, fixing the wrong answer.

If the subject in the test cycle made no more than one wrong answer, then none of the counter outputs

12 impulse (unit potential) is not in accordance with WITS.

After pressing the last button 61 of block 8 at the output of the distributor 9, a single potential (pulse) is applied to the control input of the element 20 and through element 21. a zero potential from the output of the trigger 72 of the block 19 is applied to the control input of

is fed to the register setup input 4, returning the latter to its original position. The zero potential from the output of the element 20 closes the key 18, the numbers on the indicators 56 of block 6 go out, and the timer 11 fixes the time

determine the numbers in this cycle.

At the same time, a single potential from the output of the distributor 9, through element 73 of block 19, to the control input of which zero potential is applied from the output of the IL-77 element, enters the input of indicator 78 and lights up a Successful signaling the implementation of the first (uncomplicated) part of the program and prescribing It is difficult for the experimenter (the subject) to complicate the task: for example, enter green numbers into the program for an odd number of 1, 3, 5, 49, and red numbers, in the order of 1, 2, 3, ... go to the study of the complicated program.

If the subject in the cycle allowed two or more incorrect answers, then when the second impulse of the first output of the block 8 received an incorrect response to the counting input of the counter 12, the first output of the last

in accordance with the standard potential that goes to the S-input of the trigger 71 of block 19 and translates it into a single state. A single potential from the output of the trigger 71 is applied to the first input of the element AND 74

and through the element OR 77 to the control input of the element 73, blocking its output.

The unit potential, which appeared after pressing the last button 61 of block 8 at the output of distributor 9, will ensure the return of register 4 to its original position, block the output of element 20, the zero potential from the output of which closes key 18, extinguishing the numbers on indicator 56 of block 6, and stopping timer 11 which will fix the time to determine the numbers.

At the same time, a single potential from the output of the distributor 9 will go to the second input of element And 74 of block 19, will pass to the input of indicator 79 and light a transparency. A training signal indicating that the subject has not more than five errors and a subsequent change in location

To switch to the Training mode, the subject presses the Start button of the block 33

I, providing similarly described, a new random arrangement of two-digit numbers on the scoreboard of block 6.

If the subject in the cycle allowed the sixth wrong answer, then at the second output of counter 12 there is a pulse that will go to the S input of the trigger 72 of block 19, throwing it into a single position. A single potential from the output of the trigger 72 through the OR element 76 enters the R input of the trigger 71, returning the latter to the zero position (blocking the output of the AND 74 element), through the And 77 element is applied to the control input of the element 73, blocking its output, and applied to the control inputs of the element 21, the element 32 of block 1 and the element 40 of block 2, block the outputs of the latter.

When you press the last button 61 of switch 7 in this cycle, the pulse from the output of the distributor 9 will block the output of element 20 by closing key 18, the zero potential from the output of which will quench the numbers on the indicators 56 of unit 6 and stop the timer

I1.fixing the time to determine the numbers. A pulse from the output of the distributor 9 will not pass through the element 21 to the obnu ing input of register 4, the information at the outputs of the register groups 4 will remain the same.

At the same time, the impulse from the output of the distributor 9 through the second input of element 75 of block 19, to the first input of which the unit potential is supplied from the output of trigger 72, will be fed to the input of indicator 80, having covered the Repeat banner warning the subject of assuming more than five incorrect answers and presentation in the next cycle of information on the display of block 6 without change.

The subject presses the button 33 of block 1. The pulse from its output goes to the input of delay element 22, to the second input of timer 11, setting the latter to the initial state, and through the OR 16 element to the second input of the distributor 9, returning it to its original position. Transparent Snooze Extinguished. The lock from key 18 is released, the ignition voltage is applied to the control inputs of the indicators 56 of unit 6 and timer 11 is started.
