counter 55 correct answers, counter 56 answers, counter 57 cycles and indicator 58 First stage, Second stage. The panel 14 of the test includes a button 59 Control and buttons 60 and 61 Answer.

When working with the device, the subject is asked to first listen to the control (main) sequence of characters of a given length, and then two simultaneously transmitted sequences of Morse code characters, differing in transmission speed, should be determined from the sound samples of characters i and the control transmission speed, indicating the location of the character sequences by pressing the corresponding button.

Preparing the device for operation is reduced to installation in each driver 6 and 7 using a switch (not shown) of sequences of Morse code characters, one of which, presented with a transmission speed equal to the reference speed, is the main one, and the other has a lower or a high transfer rate that interferes. Using the manual controller, the pulse frequency of the former 2 is set equal to the control sign transmission speed; on the former 3 and 4, the transmission speeds are respectively smaller and larger than the control one.

The device works as follows. .

Previously, the supervisor (the subject) determined (sets) the time during which the subject must memorize the transmission rate of the characters of the control sequence, set the switch (not shown) of the time relay 20 to the appropriate position.

When the power is turned on, the counters 55, 56 and 57 are reset to the first position — shifting registers 15 and 16, indicators 17 and 18, trigger 2 to the second position (at the first output) zero. The generator 12 starts up, giving the sound frequency to the inputs of blocks 10 and 11. On indicators 17 and 18, the first light bulbs indicate the difference between the control and interfering signal transmission rates of 5 g / min. A device 28 indicates that the device is ready for operation.

The head (subject) presses the button 59 Control. The impulse from its output goes to the first input of the trigger 23, transferring it to the first position, while the indicator 28 goes out, and a single potential from the first output of the trigger 23 is applied to the control inputs of the element 21

the key and the key 29, to the input of the relay 20 time, running the last at the time set by the switch, for example 30 s, with the unit potential from the output of the relay 20

time is applied to the control input of the prohibition element 22, and the input of the element OR 34, the pulse from the output of which the shaper initiates 2 clocks and, affecting the first (informational) input of the shaper 6 Morse codes, prepares the last for the character to be extended. Clock pulses from the output of the imaging unit 2, arriving at the clock input of the imaging unit 6, advance the character code combination from the output, which is fed to the input of the imaging unit 35 of the unit 8 and the inputs of the elements 40 and 41 of the unit 9.

If trigger 44 is currently in the first position, then the unit potential from its first output goes to the second input of element AND 40. The code combination of the sign from the output of element AND 40 is fed through element OR 45 to

5, the control input of the key 47 of the block 10, to the information input of which the tone frequency is supplied from the output of the generator 12. In the electroacoustic converter 48, a melody of the sign with the control transmission speed is heard. Subject, having listened, remembers the control transmission rate of the sign.

After the end of the sign at the output of the imaging unit 35, an impulse appears that goes to the inputs of the And 37 and 38 elements. The impulse from the output of the And 38 element goes to the first input of the imaging unit 2, turning off the last one, and to the information input of the key 29, to the control input which is given a single potential from the first output of the trigger 23. An impulse from the output of the key 29, passed the delay element 26, goes to the information input of the prohibition element 22, and passed the delay element 25, will go to the input of the OR element 34, ka, extension is carried out ET. with as described.

At the end of the time set for memorization (30 s) from the time 20 relay output, a zero potential will be applied to the control input of prohibition element 22. Upon receipt of the next pulse from the output of block 8 to the information input of the key 29.

5 pulse from the output of the latter will go to the input of the element 26 delay. The delayed pulse will pass through the element 22 of the prohibition on the second input of the trigger 23, ensuring the appearance at its first output of a zero potential, which is fed to the control

the input of the prohibition element 21, preparing the circuit for passing signals that control the interfering sequence (interference), and the control input of the key 29, stopping the supply of subsequent pulses from the output of block 8 to the second input of the driver 2. The unit potential from the second output of the trigger 23 lights the indicator 28 Answer, instructing the subject to select a check mark from the two presented melodies of characters from a given point in time.

The delayed pulse from the output of the element 25 through the element OR 34 will go to the second input of shaper 2, launching the last, at the first input of shaper 6, preparing the circuit for extending the control sign and through the prohibition element 21, at the first input of shaper 7, preparing the circuit for extending the interfering mark, and on the information inputs of keys 30 and 31.

Let at a given moment of time at the first output of the 2p trigger there is a unit potential that is applied to the control input of the key 30 and the second input of the element 32. At the output of the key 30 there is a pulse that will go to the second input of the imaging unit 3 and start it. The clock pulses from the output of the imaging unit 3, the frequency of which is lower than the frequency of the pulse following from the output of the imaging device 2, through the OR 19 element arrive at the clock input of the imaging device 7 and will advance the binary code combination of the interfering sign.

Code combinations of characters from the outputs of the formers 6 and 7 are fed to the inputs of the formers 35 and 36 and the first inputs of the And 40, 41 and 42, 43 elements, respectively. Since the unit potential from the output of the trigger 44 is fed to the second inputs of the And 40 and 42 elements, then the output of the last two. The combination of characters goes to the control inputs of the keys 47, to the information inputs of which the tone frequency is fed from the output of the generator 12. In the electroacoustic transducers 48, the melodies of various transmission speeds sound.

The subject, listening to both signals at the same time, determines in which converter 48 the melody of the Morse code symbol sounds with the reference transmission rate and presses the corresponding button 60 or 61.

When the answer is correct (the main signal is fed to block 10), the pulse from the button bb output goes to the first input of the element 49, to the second input of which the unit potential from the first output of the trigger 44 is fed and through the element OR 52 to the input of the counter 55, which will fix the correct answer. At the same time, the pulse from the output 5 of the button 60 passes through the element OR 53 and enters the information input of the prohibition element 54 and the input of the counter 56. The counter 56 will record the answer.

During the pause between the signs at the outputs of the formers 35 and 36, pulses appear that go to the inputs of the elements And 37 and 38, the pulse from the output of the element And 38 turns off the formers 2, 3 and 4. If at this time from the output of the driver

5 39 also receives 1 at the input of element AND 37, then a single potential appears at its output, which, arriving at the counting input of flip-flop 44, changes its state: at the first output it will be O, at the second output 1.

Since the control input of the element 54 is fed to the zero potential of the output of the counter 56, after the respondent’s response, the pulse from its output goes through the IL-34 element to

5 inputs shapers 2, 6 and, through the element of the prohibition 21 - to the input of the key 30, connected by the output to the shaper 3, and the input of the shaper 7, having transferred them to the following position and ensuring the extension

0 from the outputs of the formers 6 and 7 second characters. In this case, the sign of the control sequence will be given to the second, and interfering - to the first electroacoustic converter.

5 The subject, listening to the signals of both sequences, again locates the main character and presses the appropriate button. If the subject correctly identified all the characters.

0 of the control sequence, then at the outputs of the counters 55 and 56, in tf, the overflow pulses that are applied to the inputs of the And 51 element, ensuring the appearance of a pulse at its output. The impulse from the output of the element And 51 enters the input of the element 27 of the delay and passes through the first input of the element 32 to the input of the annular shift register 15, having transferred its second position. Indicator 17 lights up

0 the second light bulb, which indicates that the transmission rate of interference from the driver 3 increased by 1 g / min, i.e. driver 3 is prepared for operation in a subsequent cycle.

5At the same time overflow pulse with

the output of the counter 56 enters the control input of the prohibition element 54, prevents the starting of the formers 2 and 3 and the translation of the formers 6 and 7 into the first

position, and also returns the counters 55 and 56 to the initial state.

The delayed pulse from the output of the element 27 will go to the input of the trigger 24 and translate its second position. The unit potential from the second output of the trigger 24 is applied to the control input of the key 31 and the second input of the element 33, the output of the last pulse will not be, because the delay time of the element 27 is longer than the pulse duration. The key 30 is closed, the key 31 is opened by a single potential from the second output of the trigger 24. In the indicator 18, the first light is on. The device is ready to present the test subject with a transmission rate of the check mark at 5 g / min.

To resume the next cycle after correct recognition (difference) of the previous sequence, you must press button 60 and 61. The answer that was pressed last in the previous cycle, Let button 60 be pressed last in the cycle. The unit potential from the first output of trigger 44 of switch 9 is fed to input element AND 49 block 13.

The subject repeatedly presses button 60. The pulse from its output is detected by counters 55 and 56, i.e. the results of the indications of the indicators do not change and from the second output of the block 13 are fed to the second input of the block 1, ensuring the extension from the output of the block 5 of the control and interfering characters as described. The interfering code combination is advanced by the clock pulses of the driver 4.

With the correct answer, the latter will be recorded only by the counter 56. At the end of the cycle (presentation of the entire sequence). Consequently, the trigger 24 in block 1 is not transferred, the test subject is repeatedly presented with control signs with interfering signs of the same transmission rate.

At the end of the training, the manager (the subject) for a specified time to memorize the control signal, set on the timer (time relay) 20 of block 1 and illuminated by indicators 17 and 18, determines the degree of preparedness of the subject (s).
