The training information presentation node 1 has a series-connected clock pulse generator 11 with an adjustable pulse frequency, a program block 12, which with the help of switches (not shown) sets the Morse code characters in the appropriate sequence (in accordance with the text provided by the learner), 1 that converts the signals from the output of block 12 to the signs of the Morse code, and the sensor 14 of the Morse code, from the output of which the posyks are removed with a tonal frequency. Moreover, unit 2 for evaluating responses by the first input is connected to the input of a telegraph key 6, block 4 for discontinuing pauses is connected, by input to the inputs of a telegraph key 6 and sound generator 7, to the first inputs of trigger 5 and unit 2 for evaluating answers, the first input of which is connected to the first output node 1 presentation of educational information, the second output associated with the input of headphones 8 and the output of the sound generator 7, while the input of node 1 presentation of educational information is connected to the output of the imaging unit 3 single pulses, the input connected to the output dy trigger 5, a second input coupled to the first output of the separating unit 4 breaks, the second output associated with the first input of the counter 9, a second input connected to the output of the unit 2 responses assessment, and the output of counter 9 is coupled to the output of the unit 10 error indications.

And the circuit code And connected to the first

counter input 9.

The simulator works as follows.

The learner, in accordance with the text, transmits the first character with a Morse code, the manipulator with a telegraph key 6. When forming the first element of the character (Fig. 2o), the trigger 5 is set

Q in one state. The positive potential from the output of the trigger 5 (FIG. 2S) is fed to the driver of 3 single pulses, and the pulse formed by its leading edge (FIG. 2B),

I act on the input of the block of 12 programs, provides a transmission from its output of a signal (in accordance with the installed program), converted by the encoder 13 into a sign, for example, the code

g Morse, i.e. the leading signal, which from the output of the encoder 13 through the sensor 14 is fed to the headphones 8 (figure 2). The elementary assignments transmitted by the student control the sound generator 7, i.e. form a predetermined slave signal (Fig. 10), which from the sound generator output, the torus 7 also goes to the headphones 8. The frequency of the sound generator 7 is selected above or below 100-200 Hz of the frequency generated by the Morse code sensor 14.

If the learner transmits a sign faster (slower) (Fig. 2, 1.2 II) than the leading signal is transmitted,

The 5 head phones 8 are heard the characteristic sounds of claps, which follow them in front of a uniform tone, while if the trainee shortened the sign, then in the last clap

 he hears the tone of the master (control) Signal (sign) j, and if he lengthened, then in the last pop you will hear the tone of the slave (your) signal

: (Fig.2e).

 At the same time, the elementary sendings of the master signal from the output of the encoder 13 arrive at the first input of the adder 15, the second input of which receives the signal from the output of the telegraph key 6 (Fig. 21k. If the master and slave signals at the inputs of the adder 15 are not equal, at its output pulses (fig.2j), which, acting on the control

5 input element And 16, provide prokadoenie pulses timestamps from the generator 17 to the input of the counter (Fig.2i) connected to block 10

indications. The display of block 10 displays the value of the error admitted by the student.

Consequently, along with the hearing control of the transmission on the key, the student visually perceives the magnitude of the error} caused by a violation of the proportionality of the elementary premises.

Upon completion of the transfer of the first character of the text in the block 4 in the gap, a pulse is formed (Fig. 2k), which is fed to the second input of the trigger 5 and the installation input to the initial state of the counter 9, returning them to the initial state and preparing the simulator for transmitting the next character . If the student transmits (forms a driven signal) in tempo and rhythm, the same as the leading signal (Fig. 2III), then in the head bodies2

In the backgrounds 8, a signal of the same pitch is listened to - a uniform background and there are no pulses at the output of the adder 15.

The student by ear and visually perceives the correct transfer. In this case, the supervisor or the student himself can increase the transmission speed on the key by increasing

the frequency of the clock pulses from oscillator.11 to block 12 programs.

The use of the invention in devices for training and training of radio telegraphs allows to increase the accuracy of the device due to the visual (along with the auditory) perception of the mistakes made due to the violation of proportionality, and to improve the quality and effectiveness of training at the initial stage of training.
