The simulator works as follows.

The switches 36 in the driver 3 establish the signs (letters, numbers) that the learner must learn (remember), and in the driver 4, the same signs in a random sequence.

Turn on the power. Registers 11 and 12 are set to the initial state, decoder 38 counters and counters 10, 26, 27 and 46 are set, and trigger 16 is set to the second position (the unit potential is at the second output).

The simulator is ready to go.

The student presses the button 24 "Start. The impulse from its output through the element 36 enters the input of the element 17, to the control input of which a unit potential is supplied from the output of the trigger 16. The impulse from the output of the element 17 enters the input of the block 14, providing a single potential at the output of the trigger 5b, which is applied to the control input of the element 57 and passes the clock pulses to the input of block 14 from the output of the generator 5, to the shift input of the register 11, to the input of the counter-decoder 38 and through the element 44 to the input of the element 42. The impulse received to the input of the counter-desh fratora 38 causes the appearance at its output a logic "1 which is input to the first member 45 and through the first switch 39 to the corresponding input of encoder 40 by providing on its output forming the Morse code symbol formalized as a binary number. The same impulse from the output of element 42 enters the input of register 41, translates the latter into parallel recording mode, and passes through element 43, enters the input of register 41, ensuring parallel recording into it through the first inputs of a binary formalized number from the outputs of the encoder 40. Clock the pulses from the output of the generator 5 to the input of the register 41 extend the sign recorded in it to the control input of the key 48, ensuring the passage of the audio frequency of the generator 50 into the electroacoustic converter 52.

The student, having listened to the presented sound image of the Morse code symbol, identifies it and memorizes it.

At the same time, the code combination from the output of the imaging unit 3 is fed to the input of the register 11, in which it is recorded by clock pulses, and in block 8 for the selection of pauses. At the end of the code combination, a pulse appears at the output of block 8, which enters the input of shaper 14, ensuring that a zero potential trigger 56 appears at the output, which, applied to the input of element 57, stops the arrival of clock pulses

to the input of register 11 (determines the length of the code combination) and to the input of element 32. The pulse from the output of element 32 through element 37 enters the input of shaper 15, ensuring the appearance at the output of trigger 56 a unit potential that is applied to the input of element 57 and passes clock pulses from the output of the generator 5 to the input of the register 12 and to the input of the generator 4, providing the supply from its output, as described for the generator 3, the code pattern of the first character of the sequence, which through the key 49 and element 51 enters the electroac An oral transducer 52 is presented to the student.

At the same time, the code combination from the output of the imaging device 4 enters the register 12, by registering there the clock pulses from the output of the imaging device 15, and in block 9 for the allocation of pauses

If the student believes that the presented sound image of the Morse code mark does not correspond to the reference one, then it does not take any action. The impulse from the output of block 9 through the element 37 enters the input of the imaging unit 4 and provides the following code combination to its block 7 and to the register 12 from its output, displacing previously recorded information from the latter.

Sequence marks are presented until the learner recognizes a reference mark in the next one.

If the learner believes that the sound image of the mark is a reference mark, then he presses button 25. Impulse from button 25 output through element 23 enters the inputs of elements 53 and 54 and the input of delay element 19. If the code combination recorded in register 11 is the same as the code combination recorded in register 12, i.e. the trainee correctly recognized the sign, then the potentials 53 and 54 fed the same potentials to both inputs of each element 55. Zero potential at the outputs of the elements 55 does not change (zero potential at the output of the element 21). The response pulse through the element 30 (the delay time is equal to the sum of the response time of the elements 23, 53 (54), 55, 21, (28) and the element 29 passes into the counter 26, because from the output of the inverter 28 to the input of the element 29 enters the unit potential and captures the correct answer.The pulse from the output of element 19 returns registers 11 and 12 and counter-deflector 38 of generator 4 to its original state and, having passed through elements 34 and 36 and element 17, enters the input of generator 3, ensuring the delivery of the second reference sign.

If the code combinations are different, and the student has decided that they are the same, i.e., he has incorrectly recognized the sign, then when the button 25 is pressed, the impulse from its output, entering the node 13, causes the appearance of its sign

the output of a single potential (pulse). This pulse from the output of the element 21 enters the counter 27 and captures the wrong answer, and passed through the element OR 22,

enters the input of the trigger 16 and provides the appearance at its output of a single potential. At the same time, entering the input of the inverter 28, false triggering of the counter 26 is prevented.

The delayed pulse from the output of the element 19 returns the registers 11 and 12 and the counter-decoder 38 of the former 4 to its original state and, having passed through elements 34 and 36, enters the input of the element 18. The pulse from the output of the latter enters the input of the element 20 and the inputs of the elements 45 , ensuring fixation in the counter 46 incorrectly recognized the first character. From the output of element 20 (the delay in which is necessary for reliable operation of the counters 46) pulse

0 is fed to the input of imager 3 and provides for the re-presentation of the reference mark. Then, presented, as described, a sequence of characters from which the student must recognize the reference character.

 If the student in the sequence presented again recognizes the reference mark incorrectly, the process is repeated, and the repetition of each sign is recorded by the corresponding counter (of the given sign).

0 If the trainee did not recognize the reference mark when presenting the entire sequence, then he does not take any action. After the presentation of a sequence consisting of ten characters, the counter-decoder 38 of the imaging unit 4 moves to the eleventh position. A single potential from the eleventh output of the counter-decoder 38 enters counter 10, in which unidentified signs (missing answers) are fixed, to the input of element 22, preparing the circuit for repeated presentation of an unidentified sign, and through element 23 - to the input of element 19, impulse from the output of which, sets the initial state of registers 11 and 12 and re-submits the reference mark.

5 At the end of the cycle, from the outputs of the formers 3 and 4 (respectively, from the tenth and eleventh outputs of the counters-decoders 38) positive potentials are fed to the inputs of the element 35, which provide the appearance at its output of

potential and ignition of transparency

The cycle is completed in the indicator 31 of the console 1. The student (the teacher) takes readings from counters 10, 26 and 27, according to which the success of the training is judged, and according to 5 readings of the counters 46 they determine which Morse code characters are most difficult to master (memorized) .

Use of the invention in devices for training radio telegraphs to receive

by hearing, it allows to increase the accuracy of the simulator and reduce the training time due to repeated presentation of a sign that is incorrectly perceived or completely unrecognized by the melody, while repeated presentation of the sign is made before it is recognized correctly. Accounting for the number of repetitions of each particular character perceived with an error, and taking into account the number of unrecognized characters from the first time during one cycle, allow the student to assess the capabilities of the Morse code. This allows the teacher to divide the group of students into subgroups with approximately the same individual abilities of the students, adjust the training program for each subgroup, providing a gradual transition from working out more easily recognizable and remembered characters to difficult to remember, allowing us to make fuller use of the motivational factor forcing the learner to work with passion.
