The Morse code shaper contains counter decoder 1, program block 2, encoder 3, shift register 4, clock generator 5, first delay line 6, second delay line 7, switch 8, end of character formation unit 9, key 10, tone generator 11 frequency, block 12 changes the text transmission speed, block 13 changes the speed of transmission of the character and block 14 specifies the mode, and block 12 contains a ring shift register 15, a group of elements And 16i-16n (where n is the number of bits involved, equal to 20) and multi-input element OR 17.

Block 13 contains the first and second single vibrators 18 and 19, register 20, keys 211– 2110, and button 22, which allow you to set the initial transmission rate of characters by gradations in 4 groups per minute (h / min) ranging from 12 to 52 g / min (60-260 g / min, block 14 contains a built-in switch 23 (P - A), consisting of two switches for a short circuit and one switch for switching, the first counter 24 (with a conversion factor of five), the second counter 25 (with adjustable conversion factor from 1 dr 5) and switch 26, and block 9 consists of the element OR NOT 27 and one-shot Ator 28 (forms a short pulse).

Morse code shaper works in the following way.

In the manual mode, it provides the transmission (presentation) of text and characters for hearing processing, in the automatic mode, the transmission of text and characters for processing the increase in hearing speed with a typewriter.

Preliminarily, using the switches of software block 2, set the Morse code characters, which the trainee must work on this occupation.

To work out the reception of signs by ear, the switch 23 in block 12 is set

in position P (manual), switch 8 sets the speed at which the learner starts processing the text, for example 8 g / min, while the melody transfer rate of the character automatically sets

0 12 g / min.

When the power is turned on, counter-decoder 1, registers 4, 15 and 20 and counters 24 and 25 are set to their original position, generators 5 and 11 are started. Zero inputs from the outputs 9 (n + 1) - 2p of register 4 are fed to the inputs of block 9, ensuring the appearance at the output of an element OR-NOT 27 of a single potential (fig.b). A single potential triggers a single vibrator 28, a short pulse from the output of which (Fig.66) is fed to the input of the counter of the decoder 1 and translates it to the first position, the Single potential from the output of the counter decoder 1 through the switch 2i of block 2, set to a given letter ( figure), is fed to the corresponding input of the encoder 3, ensuring the formation at its outputs of the sign of the Morse code in the form of a binary formalized number in which the dot corresponds to

0 I, dash - Sh. And the pause between elements of the sign - O.

A single pulse from the output of the one-shot 28 block 9 through the delay line 6 (fig.bv) is fed to the first control

5 the input of register 4, having transferred the latter to the parallel recording mode, and the delay line 7 (FIG. Bg) passes to the second control input of the register 4, ensuring parallel recording of the binary

0 numbers from the outputs of the encoder 3 to the register 4 (fig. D), while filling with the ones and zeros that make up the sign, begins with the n-bit register 4.

Clock pulses coming from the output of generator 5 to the third (clock) input of register 4, the mark written in bits of register 4 is raised to the nth inclusive, in subsequent bits, up to the bit corresponding to the text transmission rate 8 g / min (fig.be). The extended elements of the sign (ones, zeros) in (n + 1} - {2g) bits of register 4 arrive at the inputs of block 12, but do not go further, since register 15 is in

5 of the initial state, to the inputs of the switch 8 and the block 9. The receipt 1 in (n + 1) -th register bit 4 provides the appearance at the output of the block 9 of zero potential. The code combination of the sign pulled out from the 1st output of the register 4 is fed through the switch 8 to the first input of the block 14 and through the closed contacts of the switch 23 (position P) to the control input of the key 10, to the information input of which the tone frequency is output from the generator - torus 11. At the output of key 10, short and long tonal frequency messages appear, i.e. melody of the sign, while the transfer rate of the sign corresponds to 12 g / min, and the transfer speed of the text 8 g / min

To change (increase or decrease) the speed of wiring (text) of the transmitted characters, it is necessary to put the switch 8 in the appropriate position.

To test the increase in the speed of receiving characters by ear with writing on a typewriter in block 14, switch 23 sets to position A (automatic), and switch 26 of inputs of counter 25, for example, to the third position (after transferring three groups of characters, speed increases).

When the power is turned on, the transmission (presentation) of the characters of the Morse code is carried out in the same way as described for the manual mode. Simultaneously, the unit potential from the second output of unit 14 is fed to the first input of unit 13, the input of the one-oscillator 18, causing the appearance of a short single pulse at its output. The pulse from the output of the one-shot 18 is applied to the inputs Ci and Vi of register 20 of block 13 and to the inputs of Ci and Vi of register 15 of block 12, writing a unit to their first bits.

The output of the first register bit 20 is freed, the generator 5 does not change the clock frequency, i.e. characters (melodies) are transmitted at a speed of 60 g / min.

A single potential from the first output of the register 15 is fed to the first input of the AND 16T element whose second input is connected to the 2p output of the register 4, i.e. the appearance of a single potential at the second input of the element I 16i ensures the transfer of text at a speed of 30 s / min.

The binary combination of the first character from the output 2p of the register 4 is fed through the elements AND 16i and OR 17 of the block 12 to the third input of the block 14, which through the switch 23 is connected to the first output of the block 14. The code combination from the first output of the block 14 goes to the signal input of the key 10, ensuring the appearance of the melody of the mark at its output.

A pulse from the output of block 9 is fed to the second input of block 14 and fed to the counting input of counter 24, recording the transmission of the first character of the group. The following marks are fixed in the same way.

When the fifth pulse arrives (the last character of the group is transmitted), an overflow pulse appears at the output of the counter 24 of block 14, which records the unit in the counter 25.

After transmitting three groups of characters, a pulse appears at the output of counter 25 (FIG. 6b), which from the third output of block 14 is fed to the second input of block 12 (input Cg of register 15), ensuring the appearance of a single potential at its second output, which is applied to the first input element and 162

The next three groups of characters are transmitted at a speed that is higher than the previous one by 1.5 g / min, etc. (Fig.6).

The transfer of the last three groups of characters in the cycle is carried out at a speed of 12 g / min. After transmitting the fifth character from the third (last) group, a pulse appears at the output of the counter 25, which is fed to the input C2 of the register 15 of the block 12, changing it to the n + 1-e (first) position. The pulse with n + 1 output is fed to the input of the one-shot 19 block 13, running the latter. A short pulse from the output of the one-shot 19, entering the input of the Ca register 20, will transfer the unit in the last from the first to the second output, called the potential of the input of the key 211. The pulse from the output of the key 211 applied to the corresponding control input of the generator 5 increases the speed the effects of clock pulses, and therefore, the transfer rate of the melody of the character increases, is 16 g / m, and the text transfer rate in the next cycle varies from 8 to 16 g / min.

The next cycle provides the transfer of the sign at a speed of 20 g / min, and the text - from 10 to 20 g / min, etc.

Increasing the speed of reception by ear with writing on a typewriter is done at each lesson, for which the teacher, before training, sets on block 13 the corresponding speed of transmission of the sign (text) by pressing button 22. Each pressing of button 22 converts the unit in register 20 to one bit, those. Increases transfer speed by 4 g / min.

Briefly stopping the transmission of characters is accomplished by pressing the Stop button.

The use of the invention for teaching radio telegraphs extends the didactic capabilities of the Morse code generator by automating changes in the character and text transmission rates, and the character transmission speed changes abruptly (steps) in 20 h / min, starting at 60 h / min, which provides start learning to listen
