Block 10 contains a prohibition element 39, key 40, first 41 and second

42 elements of IDN. t

Block 1I contains a demultiplexer 43, the first - the fourth shift registers, the first - the fourth delay elements, the group of four-input elements AND 46, -46p (where.n is the number of gradations that determine the reaction time of the student), RS-triggers, multi-input element And 48, the first 49 and second 50 single-vibrators, element 51. barred, key 52, divisor 53 into three, first 54 and second 55 dividers into two, and the pair button 56 Record a dash.

The simulator works as follows.

The switches 15 preset the characters of the Morse code, for example, F, I, P, B, Pi, etc., which need to be worked through in the training process.

Turn on the power. The first register 44 of block 1 is reset. Using a button (not shown), a register is entered into register 34, which is pushed so that, from generator 7 output, the clock feed rate corresponds to the transfer rate that the student has reached by that time, for example, ten groups per minute. By briefly pressing (until the signal appears in the headphones of the electroacoustic converter 2) the button 56 is provided through the OR 41 element, the start of the generator 7, the impulse feed10

Combined with the dash from the output of divider 53 of block 1 1 and the pulse of pulses from the first, the output of generator 7 to the information and shift inputs of register 17 and its filling with the 111 and 000 combinations.

The simulator is prepared to determine the reaction time of the student and the follow-up of the training in the transmission of characters.

The button 13 is pressed. The pulse from its output goes to the R-inputs of the trigger I-47 of block I1, providing the appearance of units to the reverse outputs that are fed to the inputs of the AND 48 element. The unit potential from the output of the AND 48 element is fed to the control input of the element 39 blocking block 10, preventing the arrival of pulses at the input of counter-decoder 14, to the control input of key 40, preparing the circuit for register 17 to work as an annular circuit, and through the OR 41 element to the input of generator 7, ensuring the latter to start (Fig.Za) .

At the output of the divider 53 (Fig. 36), a single potential appears, which triggers the one-shot 50, providing a short pulse at its output, commensurate with the pulse of the time stamp applied to the inputs VI of the registers 44 (Fig. D), and arrives at information input element 51 prohibition. A single potential from the output of the element 51 is applied to the control input of the key 52, to the information input of which time stamps are supplied from the second output of the generator 7 (Fig. 3g). The time stamps from the output of the key 52 are received at the information input of the de-multiplexer 43.

the multiplexer provides the appearance of time marks at its outputs. The perceived sound image of the dash, which is trained immediately, with a delay of the reaction time, reproduces the dash on the telegraph key 3 (Fig. ZJ). The dashes formed by the learner arrive at the control input of the prohibition element 51 stopping the entry of a single potential from its output to the control input of the key 52. The arrival of time stamps from the second output of the generator 7 to the input C1 of the register 44 also stops (Fig. 3g). At the corresponding output of register 44, there appears a single potential that determines the reaction time of the student and is fed to the input of the corresponding element I 46.

Displaying banners in block 6 when determining the reaction time indicates the absence of unambiguity in the actions of the student (range of reaction time) and the impossibility of his training according to the method of the leader. When the second pulse arrives from the output of the divider 53, the simulator operates in the same way as described, while the time stamps are in ms at the second output of the demultiplexer 43 and will advance the unit in register 44 ,,, when the third pulse arrives - in register 443, and the fourth - in the register 44.

If the reaction time at least for a time stamp is different in one of the four actions of the student, then the next sigg will be presented

In this case, the presence of zeros at the address inputs of the demultiplexer 43 ensures the appearance of time marks on its first output, which arrive at the input of the delay element 45 and the input

the multiplexer provides the appearance of time marks at its outputs. The perceived sound image of the dash, which is trained immediately, with a delay of the reaction time, reproduces the dash on the telegraph key 3 (Fig. ZJ). The dashes formed by the learner arrive at the control input of the prohibition element 51 stopping the entry of a single potential from its output to the control input of the key 52. The arrival of time stamps from the second output of the generator 7 to the input C1 of the register 44 also stops (Fig. 3g). At the corresponding output of register 44, there appears a single potential that determines the reaction time of the student and is fed to the input of the corresponding element I 46.

Displaying banners in block 6 when determining the reaction time indicates the absence of unambiguity in the actions of the student (range of reaction time) and the impossibility of his training according to the method of the leader.

arrives at the adjustable delay element 9, determines its delay time equal to the reaction time of the student. The zero potential from the reverse output of the trigger 47 through the element And 48 enters the control input of the prohibition element 39, opening the way for the pulses to go from the output of the driver 5, and to the control input of the key 40, turning the register 17 from ring to shear. A change in the potential at the input of the one-shot 49 will cause the appearance of a pulse on its

the output that arrives at the input of the element OR 37 and returns to its initial state the counters 22-24 and 36.

The impulse from the output of the imaging unit 5 enters the input element 1 8 and the input of the counter-decoder 14, providing at the first output the appearance of a single potential, which through the switch 15 arrives at the output of the encoder 16, providing at its outputs the sign code indicated on this a switch, for example, F, in the form of a binary -normalized number, in which the dot corresponds to 1, the dash is 111, and the pause between the elements of the sign is O.

From the output of the element 18, the pulse arrives at the input of the V2 register 17, switching it into parallel recording mode, and through the element 19 enters the input of the C2 register 17, ensuring that the binary number from the outputs of the decoder 16 is written into the register 17. The clock pulses from the output of the generator 7 arrive at input C1 of the register 17 and a binary combination of the sign from the output of the register 7 to the element 9 and to the input of the electroacoustic converter 2 is transmitted. The elements of the sign also enter the counter 36, which records the number of incoming elements. Detained by element 9 at the time of the student's reaction, the elements of the sign arrive at the information input of element 20 and at the entry prohibiting element 21.

If a student transmits signs at a given rhythm and tempo, then there will be no impulses at the output of elements 20 and 21 If the trainee shortens the transmitted element of the sign or extends a pause during the transmission, then an output appears at the exit of element 20. which enters the input of the counters 22 and 24. If the student during the transfer extends the transmitted element of the character (shortens the pause), then the output of element 21 is a pulse that arrives at the input of the counters 23 and 24.

Upon completion of the transfer of the first character from the output of shaper 5 to the input element 18 and to the input of the counter-decoder 14 receives a pulse, which translates the counter 14 to the second position, ensuring the formation of the next sign of the Morse code. The process is repeated.

Since the trainee in the nepe-i process of giving a mark allows for the same type of inherent errors, filling one or another counter 22-24 depends on what type of error is present. If the reaction time has increased compared to the measured one, then overflow occurs counter 24. Impulse

The 1Q overflow from the output of the counter 24 enters the input of the transponder 33, on which the cause of the error is highlighted. The trainee is re-checked; the reaction time or training is shortened, since the increase in reaction time is due to the deterioration of the functional state of the learner.

When the students exceed the permissible number of errors, the overflow pulse from the output of the counter 22 enters the input of the transparency 31, on which the cause of the error is highlighted. The same impulse comes through element 12

25 to the input of register 34, providing a reduction in transmission speed by one group

per minute, and through elements 37 and 38 - to the installation inputs of the counters 22-24, 36, transferring them to the initial state. The trainee is presented with the following sign with reduced speed.

In the absence of errors in the transmission of a certain number of characters, an overflow pulse appears at the output of counter 36, which, entering the input of register 34, provides an increase in the transmission speed by one group per minute, and through elements 37 and 38 - to the installation inputs of counters 22-24 , 36, set them back to their original state. Trainee is the next sign with increased speed.

The introduction of a time set and a synchronization block into the simulator made it possible to increase the efficiency of the simulator by measuring the reaction time of the learner before training and automatically determining and setting the required delay time when switching to transmitting Morse code characters.
