and are the second input of the block, the inputs of the elements 32,33 and 34 are the third, fourth and fifth inputs of the block.

The test console 8 contains a keyboard 39 with buttons, single-pulse generators 40 and 41, triggers 42-44, the inputs of which are combined and the input of the block, trigger codes 44.43 and 42, the first, second and third outputs, respectively, the generator 40 output the fourth output of the block, and the generator output the 41st output of the block. The device works as follows. When the Start button on the remote control 8 and the output from its output is turned on, its signal goes to the second switch start switch 27 of the distributor 10 and sets the trigger 27 to the zero state. The same pulse includes the encoder 17, the signal from the output of the second, depending on the installed switches on the switch 16, selects the corresponding sign on the electronic Morse code sensor Former 4. The Morse code sign from the Former A output goes to the electroacoustic transducer 5 and presents and the form of the sound image to the subject, as well as to the first inputs of elements 18, and 19 I. The signal from the output and the encoder 17 through element 2 S1I is also fed to the count input of trigger 3, which is preset to zero This is a vision (not shown), and translates it into a single position. The unit potential from the direct output of trigger 3 goes to the second input of element 18 I, and the zero potential from the inverse output goes to the second input of element 19 I. Consequently, the Morse code sign from the output of shaper 4 passes through element 18 I and element 11 IZH to input A count of 13, which counts the number of incoming elementary sums (made up of a mark) and ensures that the incoming information is stored. When the next signal arrives at the output of the encoder 17, a second indicator of the programmed pair order is selected in the Morse code electronic sensor edovateLnsti which is output from shaper A on yostupaet electroacoustic transducer 5 and pred is in the form of the sound image of the subject. At the same time, this signal is fed to the primary inputs of elements 18 and 19 I. The signal from the output of the encoder 17 is also fed through element 2 of the ILNG to the counting input of trigger 3 And transfers it to the zero state. The unit potential 5 from the inverted output 3 enters the second input of element 19 I, and the zero potential from the direct output goes to the second input of element 18 I. The second sign of the Morse code from the output of shaper 4 passes through element 19 AND and element 12 OR on the input of the counter 14, which counts the number of received elementary mark of the mark and will provide information storage. The capacity of the counters 13 and 14 is equal to six (selected, based on the maximum number of elementary order in the sign of the Morse code). The subject, having listened to the sound images of both signals, makes a decision about the ratio of the elementary parcels to them. If the number of elementary sacks in both signs is the same, for example, four toppings, and the test subject has the same solution, he presses the button on the remote control 8, thereby ensuring the supply of the unit potential from trigger 44 to the first and last Then presses a Key. Enter an answer. A single pulse from the output of the generator 41 turns on the generator of 15 pulses, and pulses from its output go through the second inputs of elements 11 and 12, OR to the information inputs of counters 13 and 14. When the third pulse from the output of the generator 15 arrives, counters 13 and 14 overflow and an overflow pulse appears at their outputs. An overflow impulse from the input of the counter 13 enters the first (informational) input of the prohibition element 28, the first entry of the element 31 I, the second (“forbidden” input) the input of the prohibition element 29 and the element 35 OR ha in the code of the generator 15, obayychiv it yklyu 1, to the second inputs of the counters 13 and 14, ensuring their Installation and the initial state, and to the input of the element 38 NOT. At the same time, the impulse overflows from the output of the counter 14 hotty to the second input of the prohibition element 28, the second input of the element 31 And and the first input of the prohibition element 29. The elements 28 and 29 pass through the impulse, since an impulse (unit potential) is applied to the prohibiting signals, and from the output of element 31, it goes to the second input of element 33, and the first (control) input of KOTOjporo is given a single gutane. From the output of the element 33 And the pulse through the element 36 OR comes to the input of the counter 20 and records the correct answer. If the subject made a decision that the number of elementary dressings in the first character is greater, then he presses the More button. Thus, 7110 feeds a single potential from Trigger 42 to the first input of the 32 I element. Then he presses the Enter Answer button Since the second input of the 32 element And the impulse does not come, then from the output of the element: nta 36 OR to the input of the element 37 a logical zero is NOT supplied. The logical unit from the output of the element 37 is NOT fed to the first (informational) input of the prohibition element 30. With occurrences and overflows at the output, the counts of hooks 13 and 14 last through element 35 OR arrive at the input of element 38 of the NOT, from the output of which the logical zero of the second (prohibition) input of element 30 is opened, which opens it. At the exit of element 30, a pulse appears, which is fed to the input of counter 22 and captures the wrong answer. If the number of elementary parcels in the first character is greater than in the second, and the subject made the correct decision, i.e. pressed the More button after pressing the Enter Answer button, the first appears to be an overflow pulse at the output of counter 13. 3f IMPulse through the first (informational) input of prohibition element 28, (informational) input of element 32 AND, element 36 OR enters counter 20 and at the same time, the impulse from the code of element 35 OR, captures the input of element 38 NOT, from the output of the latter fixes a logical zero to the second (prohibiting) input of element 30, but the output 30 does not work, since simultaneously with output element 36 OR enters mpuls on V54od NOT element 37 that supplies a logic zero at the first (data) input member 30 ban. Consequently, with the correct answer, an impulse appears at the first output of the analysis unit 7, and if wrong, at the second output. This impulse, regardless of which output it goes through, will go through element 25 OR distributor 10 to element 23 AND, to the second input of which a unit potential is supplied from the output of inverter 26. The impulse from element 23 output enters through the second input of unit 1 to the control input of the encoder 17, which issues a command to the electronic sensor, the driver 4 for the presentation of the next (second) pair sequence. At the same time, the pulse from the output of element 23 I enters the inputs of the flip-flops 42-44 and sets (confirms) them to the zero state. The cycle is repeated. If the subject makes a certain number of correct answers, for example 10, then the output of the counter 20, corresponding to the given number of answers, removes the signal, which will turn the trigger 27 into a single state and provide the appearance of the output element 24 of the signal AND. This signal, having arrived at the switch 16, disconnects it from the encoder 17 and stops outputting the signals from the latter, and affects the third input of the test recording unit 21, highlights the test results on the scoreboard (not shown). According to the test results shown in accordance with the developed methodology, the test subject's suitability for radio telegrapher testing is determined. The use of the device in the selection of entrants to educational institutions makes it possible to increase the accuracy of the device and improve the quality of selection for teaching a radio telegraphist specialty by detecting the subjects' presence of certain inclinations of aural perception of the structure of Morse code characters. The structure of each signal in the listened pair of signs is evaluated and compared by a melody by means of a holistic perception by the auditory body of each radio telegraph sign and detecting their difference, which speeds up the process of developing the skill of hearing radio reception for students, shortens their preparation time and ensures maximum operator efficiency. activities of radio telegraphists.
