The appearance at the control input is the elec tronic ones (letters).

Ment 21 of the zero potential generator 1 from the one-shot 29 output provides clock pulses from the generator 17 output through element 21 to generator 20 input, register 19 input and AND 34 element to And 36 and 38 element inputs. Since the second inputs of And elements 37 to 38 served a single potential from the second

symbols), and the single potential from the second output goes to the control input of the element 72, preparing a circuit to turn on the generator 68, and turns on the indicator 67 Information on the console 11, notifying the operator that information is present in which he must distinguish ( control) and signal (information) The alternating appearance of zero potential at the control input of element 21 (Fig. 14, a) ensures that clock pulses pass from the output of generator 17 (Fig. 14.6) to the input of generator 20 (Fig. 14, c ) and on one input of the register 19, and the binary sequence The information from the output of the generator 20 to the other input of the register 19 is the last. At the same time, the code combination from the outputs of the register 19 is fed to the first inputs of the elements And 57.

The fixing of the sixth clock pulse by the counter 18 ensures the appearance of an overflow pulse at its output (Fig. 14, d), which triggers the one-shot 29 (Fig. 14, a). Single potential output from one-shot

29 stops the advancement of the binary sequence in register 19, providing a flashing of the information symbol, and, having passed through the information input of the And 72 element, post ™ goes to the first input of the generator 68, including the last one (Fig. 1, e). the time stamps from the first output of the generator 68 through the element 70, to the second input of which the unit potential is fed from the second output of the trigger 69, are sent to the information input of the register 82, recorded in it by clock pulses from the output of the element OR 85, entering the input of the register 82,

If highlighted on the indicator. If the symbol (letter) is not a control unit, then when a pulse arrives Poll from the output of the imaging unit 31 (Fig. 14, e) through element 42, to another input of which the unit potential from the output of trigger 39 is fed, the inputs of blocks 7 and 8 to the second the outputs of the latter appear pulses that arrive at both inputs of the element And 80. The pulse from the output of the element And 80, applied to the input of the trigger 75, causes the appearance at its first output

a single potential that arrives at triggers 74 and 75 by switching (is placed at one input of element AND 79. The zero potential from the second output of trigger 75 is applied to the control input of element 7 7 of the prohibition.

The operator, recognizing the signal symbol, presses the button 64 No remote 11. The pulse from its output (Fig.14, g) delivers; c to the information input of the prohibition element 76, but does not go any further, since a unit potential from the second output of the trigger 74 is fed to its control input, to the other input of the I 79 element, the pulse from whose output goes to the input of the counter 48, fixing the correct answer , and, passing through the element OR 73, is fed to the input of the trigger 69, providing the appearance of a single potential at its second output. The delivery of timestamps from the first output of the genator 68 to the inputs of register 82 is stopped (, e).

Time marks from the second output of the generator 68 (Fig. 14, h) with a frequency one hundred times greater than the frequency of the time marks at the first output go through the element OR 84 to the input of the register 82, pushing its contents (units) through the element And 8 C , on the first input of which unit potential is applied

from the output of the element And 79, to the counting input of the counter 86., recording the duration of the response (selection time) to the signal symbol.

At the end of the advancement of information pulses (time stamps) from the output of the register 82, the zero potential appears at the output of the OR 85 element (Fig. 14, and). Due to the potential drop, a single pulse (Fig. 14, k) appears at the output of the generator 83, which is fed to the second input of the generator 68, including the last, and

to the trigger input 69, switching it to the first position (at the first output is a single potential), i.e. preparing the circuit for supplying timestamps from the first output of the generator 68 to the regisp 82;

Upon completion of the presentation of the symbol, a pulse appeared at the output of the one-shot 22 (FIG. 14, l) passage through an element 43, to the second input of which

5, a single potential is supplied from the output of the trigger 39, to the counting input of the counter 44, which determines the cycle time (100s 150, 200 presentations), fixing the symbol presentation, and confirming them to the second position (the second potentials are single potentials).

If the control symbol is displayed on the indicator of block 10, the code combination at the output of register 19 is the same as the code combination of one of the registers 55, for example, block 7. When a pulse arrives Poll from the output of the forcing .31 to the third input of block 7 at the first output the last appears a pulse, which through the element OR 47 enters the input of the trigger 74, causing the appearance at its first output of a single potential, which is applied to the first input of the element And 78, to the input of the counter 50, fixing the presentation of the control letter, and to the trigger input 45, switching it to one state.

If the operator correctly identifies the control symbol and presses the 63 Yes button on the remote control 11 in time, then the pulse from the output through the element 41 enters the input of the counter 49, fixing the correct answer, and the second input of the element 78.

Simultaneously, the pulse from the output of the button 63 is fed to the input of the counter 48,

20

fixing the answer, through the element OR 73 - to the input of the trigger 69, providing the appearance of a single potential at its second output. The zero potential from the first output of the flip-flop 69 stops the filing of time stamps from the first output of the generator 68. Recording in the register 82 stops.

The time stamps from the second output JQ of the generator 68 are received through the element 71 and the element OR 84 at the input of the register 82, providing information advancement (timestamp pulses) from its output at the input of the counter 86, fixing the response time to the check symbol. The rear edge of the pulse from the output of the element OR 85 provides for the appearance at the output of the imaging unit 83 of a single pulse that goes to the second input of the generator 68, turning off the last one, and to the input of the trigger 69, switching it to the first position.

Upon completion of the presentation of the symbol on the indicator of block 10, the falling edge of the pulse from the output of the one-shot 29 triggers the one-shot 22. The pulse from the output of the one-shot 22 transfers the triggers 74 and 75 to the initial (zero) position.

If a control symbol is presented - at the first output of the trigger 74 there is a single potential, and the operator pressed the button 64 No, then the pulse from its 35 output passes through the element 76 prohibiting the input of the I L element, ensuring that the register 82 is overwritten into the counter 86 2, which fixes the invalid response to control character.

If a signal (information) symbol is presented, then there is a unit potential at the first output of the trigger 75, and the information of the counters 49 and 50 is not shown. indicators 53 and 54, coming from the outputs of the decoders 51 and 52, and information of counters 86 on indicators 88, coming from the decoders 87. The pulse from the output of block 9 enters the trigger input 16, turning off the generator 17, and through the element OR 94 to the input. trigger 90, confirming its zero state.

By the number of control symbols presented and the number of correct answers, attention concentration is judged, and by 15 (the number of time marks is probably an inverted control and signal (information) symbols — the selectivity of attention determined by the speed of choice.

If the binary combination at the output of counter 49 corresponds to the binary combination at the output of counter 50, then the output of block 9 is a pulse that arrives at the input of element 46, at the input of divider 26 and at the input of trigger 90, switching the latter. A single potential from the output of the trigger 90 includes a generator 89 interference.

In the next (second) cycle, information is presented to the operator against the background of sound interference, switched on periodically (after four clock pulses). The delayed pulse from the output of element 46 returns the counter 44 to the initial state.

At the end of the second cycle, a pulse appears again at the output of the counter 44, which is fed to the control input of the block 9.

If the operator in the second cycle (with noise) correctly identified all control characters, then the pulse from the first output of block 9 is fed to the input of trigger 90, confirming its position,

If the binary combination at the output of counter 49 corresponds to the binary combination at the output of counter 50, then the output of block 9 is a pulse that arrives at the input of element 46, at the input of divider 26 and at the input of trigger 90, switching the latter. A single potential from the output of the trigger 90 includes a generator 89 interference.

In the next (second) cycle, information is presented to the operator against the background of sound interference, switched on periodically (after four clock pulses). The delayed pulse from the output of element 46 returns the counter 44 to the initial state.

At the end of the second cycle, a pulse appears again at the output of the counter 44, which is fed to the control input of the block 9.
