The invention relates to communication technology, in particular to code converters.

Known for the main author. St. No. 2il57i code 2 converter to Morse code containing a reader, input register, symbol decoder, Morse code generator and clock generator, the decoder of service combinations is connected to the outputs of the input register, the outputs of which are connected via a collective circuit of service combinations connected in series to a single-channel and input "prohibition of the valve, whose output is connected to the input" stop, and the input through a time delay - with the output "sync pulse reader, which, in turn, black Without a second time delay, it is connected to the input “polling the decoder of service combinations, while the collective scheme of service combinations is simultaneously connected to one Hi inputs of another collecting circuit, which by its output is connected to input“ reset of the input register, and the second input is simultaneously connected to input “start of reading device and through the time-delay to the output of the “read code generator Morse code 1.

However, the well-known code converter No. 2 in the Morse code has a low probability of accurately converting the characters H and "4 codes Ifg 2 into the Morse code.

The purpose of the invention is to increase the likelihood of accurately converting the characters "H and" 4 codes No. 2 to the Morse code.

To do this, the code converter 2 is a Morse code containing a reader, an input register, a decoder of sign combinations, a combinator, a Morse code generator and a clock generator. The decoder of service combinations is connected to the outputs of the input register, the outputs of which are connected in series through the collective circuit of service combinations in series to the one-oscillator and the input "prohibiting the valve, whose output is connected to the input" stop and the input through. time delay - with the output of a “sync pulse reader, which, in turn, is connected via the second time delay to input“ interrogation of the decoder of service combinations, while the collective pattern of service combinations is simultaneously connected to one of the inputs of another collective circuit, which by its output is connected to input "reset input register, and

the second VHS / .OM is simultaneously connected to the “start of reader” input and through a time delay to the output “reading of the Morse code generator, serially connected memory block and character recognizer are entered, the second input of which is connected to the output of the additional decoder, while the inputs of the additional decoder are connected with the corresponding inputs of the decoder of sign combinations, the output of the “H and” 4 and the control output of which are connected respectively to the signal input of the memory unit and to the third input of the A signer, the output “H and output” 4 of which are connected to the corresponding inputs of the Morse code generator, and the clock inputs of the additional decoder and the memory block are connected to the corresponding outputs of the clock generator.

The drawing is a functional electrical circuit of the device.

The Converter code No. 2 in the Morse code contains a serially connected reading device 1, an input register 2, a decoder 3 sign combinations, a combinator 4, a Morse code generator 5, the input of the Morse code generator 5 connected to the output of the clock generator 6, to the outputs of the input register 2, the decoder 7 of the service combinations is connected, the outputs of which are connected to the decoder of 3 sign combinations and the shaper 5 of the Morse code, and through the collecting circuit, 8 service combinations are connected in series to one To the selector 9 and the input “prohibition of the valve 10, whose output is connected to the input“ stop, and the input through time delay 11 - to the output “sync pulse of the reading device 1, which, in turn, through the second time delay 12 is connected to the input“ poll of the decoder 7 service combinations, while the collective scheme 8 service combinations simultaneously connected to one of the inputs of the other collecting circuit 13, which its output is connected to the input "reset input register 2, and the second input simultaneously connected to the input" start reading devices 1 and, via time delay 14, to the output “reading the driver 5 of the Morse code, the memory unit 15 connected in series and the recognizer 16 characters, the second input of which is connected to the output of the additional decoder 17, while the inputs of the additional decoder 17 are connected to the corresponding inputs of the decoder 3 sign combinations, the output of "F and" 4 and the control output of which are connected respectively to the signal input of the memory block 15 and the third input of the discriminator 16 characters, the output of the "H and output" 4 of which are connected to 5 sponding input of the Morse code, and the clock inputs of the decoder 17 and the additional block

15 memories are connected to the corresponding generator outputs of 6 clock pulses.

The device works as follows.

Convertible combination code No. 2 g of the output of the reader 1 enters the input register 2 and decipher 3 character combinations. The signal from the output of the decalphator 3 sign combinations about the arrival at the device input of the next (К -f 1) -th combination “Ш,“ Э, “Ю or« рус enters the input of the resolver 16 characters, after the first clock (К-f 1) - first cycle of the generator 6 clock pulses. Before this, after the eleventh cycle of the K-th cycle, information about the recorded character (“H or“ 4) from one of the outputs of the input register 2 is fed to the input of the decipher 3 character combinations and from its output “H” and “4 to the input of the recognizer 16 characters.

The decrypted combination from the other output of the decoder 3 sign combinations enters through the combinator 4 to the input of the Morse code generator 5, from the additional output of the decoder 3 sign combinations information about the character of the recorded character is transmitted to the memory block 15.

From the output of the memory block 15 after the second cycle of the K-th cycle of the device operation, the information enters the recognizer of 16 characters. The 16 character recognizer analyzes the (K-1) -th and (K + 1) -th-sign accessories to the numeric or alphabetic registers, if they were alphabetic register characters, then the character "H" or "4 generators of Morse code is reproduced as the letter" H.

The framing characters of the digital register (except for the letters W, W, E, S) and the "space" are perceived by the recognizer of 16 characters as a digit and a sign or "4 - is reproduced as the digit" 4.

Thus, the device increases the likelihood of correct conversion of the source text in code No. 2 into text in Morse code, in which the characters "H and" 4 correspond to the signs "H and" 4 of the source text.

The proposed device makes it possible to increase the likelihood of correctly recognizing the letter "H and numbers" 4 source text, indistinguishable in code No. 2 in all cases without exception of the transfer of semantic text and partially codograms, which distinguishes it from the known.
