The disadvantage of this simulator is the low efficiency of the training of radio telegraphists, since simulators for developing the skills of transforming signals from trainees do not give a complete picture of the proportionality of elementary premises in Morse code signs. The purpose of the invention is to increase the effectiveness of training by developing proportionality by memorizing the melody and rhythm of the corresponding Morse code sign with subsequent reproduction (repeating method) and indicating the cause of the proportionality violation.

a clock pulse generator 26, the second input of the key 29 being connected to the sound generator 30, and the input of the second delay element 27

associated with the output of the imager 5 single pulses.

The simulator works in the following way.

On a block of 20 programs with switches (not shown), we set the sign of the code, for example A. At the same time, by dialing the combination of the sign of the code in block 20, the counter 15 is reset. The simulator is ready to go.

The learner presses the Start button. The signal from the output of button 18 through the first input of the element OR 4 goes to the driver 5. The front of the incoming signal generates a pulse (short), which from the output of the driver 5 goes to divider 14 and to the control input

block 20 programs. The impulse received in block 20 reads the signal .. code from the last one to the encoder 21, k6 the second transforms it into a sigil. Morse code sign (A).

From the output of the encoder, 21 characters of Morse code (unmodulated) nocTynaei to the first (informational) input of the And 12 element (but do not pass to the adder 8, since at its second input

there is no control signal) and through the sensor 22 to the electroacoustic transducer 7 (FIG. 2). The student listens to the sound image (melody) of the sign A, which he must reproduce. Having removed the melody and rhythm of the mark by ear, the student plays it with the help of a telegraph key 19 (Fig. 25). When the key 19 is pressed, the signal arrives at the first input of the adder 8, the control input of the element 10 and the leading edge of the first element of the sign ( In our example, the point translates trigger 2 from the zero state into a single state (Fig. 2b). The unit potential from the output of the trigger 2 through the second input of the element OR 4 enters the input of the former 5. The single pulse formed by the former 5 passes to the divider 14 and records in the counter 15 forms The student learns the sign of the Morse code and, acting on the control input of the 20 programs, provides a read from the last signal of the code to the encoder 21. Which converts the latter into a sign of Morse A. This sign (control) goes to the first input of the And 12 element ( Fig. 2 2) and through (Sensor 22 to the electroacoustic converter 7 (Fig. 2a). The learner has the ability, in the process of forming the sign, to listen to the control (predetermined) sign. At the same time, a single potential from the trigger code 2 enters the second (control) input of the element 12, ensuring that the control signal passes to the second input of the adder 8 and the control input of the element (11) (FIG. 22), eliminates the generator of 3 pulses, ensuring the flow time marks on the information input of the element AND 9 (fig.2d). If the learner generates a signal (fig.25), the duration of which is less than the duration of the control signal (fig.2o), then the output of the adder 8 appears pulses (fig .2 e). These impulses act on the first the (control) input of the AND 9 element, ensuring the passage of time marks from the generator 3 to the information inputs of the AND 1G and 11 elements. In this case, the transit time of the AND 10 Ci) and 11 () elements in the open state is determined by the influence of the generated and control signals to the control inputs of the elements And 10 and 11. Since i / t ,. then at the end of the formation of the trainee sign from the generator 3 through the element 11 on the second input of the registration block 13 will receive more time marks (FIG. 24) than through the element I-10 on the first input of the registration block 13 (figure 2 :). This ensures that the transparency of the fire 16 quickly, which indicates to the learner the need to transfer more slowly. The student presses the button 18, Start. The trigger 2 switches to the zero state, the generator 3 is turned off. In the electroacoustic transducer 7, the melody of the control signal (of the same, ie, sign A) signal sounds. The student, having listened to the signal again (sign A), with the help of the key 19 reproduces it, but at a lower speed. In this case, the simulator circuit works similarly to that described. If the learner generates a signal (Fig. 25), the duration of which is longer than the duration of the pilot signal (Fig. 2), then the output of the adder 8 is also in pulses (Fig. 2e). Since the open time of the element And 10 is longer, element And 11, Tet t, then at the end of the trainees the formation of a Morse code mark at the first input of the registration block 13 from the generator 3 through the And 10 element enters a larger number of time marks (FIG. 25K) than through the And 11 element at the second input of block 13 registration (figure 2 4.), which ensures the ignition of the banner 17 Medley nno. This indicates that the trainee transmitted slowly and should be transmitted faster. If the signals that were input to the inputs of the adder 8 from the output of the element And 12 and the telegraph key 19 are equal, then the output of the adder 8 will not have pulses, therefore, there is no signal at the first (control) input of the element 9. Imports (time stamps) coming from generator 3 or the second (informational) input of element AND 9 will not pass to the inputs of elements AND to and 11, and in block 13 of registration nothing will be recorded and transparencies 16 and 17 will not light up. This indicates that the learner has mastered the melody and rhythm of the sign being studied. Counter 15 will record the number of repeats required to complete the sign. The trainee proceeds to working out the next sign of the Morse code. For this, in block 20 of the programs, a new code mark is set by the switches, and the counter 15 is reset. Depending on the character being processed, for example, A, we install the switch 23. The positive potential arrives at the corresponding input of the encoder 24 to form at its outputs the sign of the Morse code indicated on the switch 23 as a binary number, in which the point corresponds to 1, a dash a pause between the elements - O. When the Start button 18 is pressed, a pulse from the output of the imaging unit 5 is fed to the input of delayed element 27 of node 6. From the output of element 27, a pulse arrives at the input of register 25, making The latter is in parallel recording mode and, having passed through element 28, is fed to the input of the Cg register 25, providing parallel writing of a binary formalized number (A code. Morse code) from the outputs of the encoder 24 to the register 25. Clock pulses from the generator output.26 at input C of register 25, the elements of the sign are sequentially extended from its output. The use of the invention in devices for training and training radio telegraphists increases the effectiveness of training at the initial stage of training.
