Известны устройства дл формировани кода Морзе.Devices for generating Morse code are known.

Такое устройство использует промежуточный параллельный неравномерный код, несущий информацию о наличии и положении моментов тире В передаваемом знаке, а также о длительности знака в коде Морзе.Such a device uses an intermediate parallel non-uniform code that carries information about the presence and position of the dash moments In the transmitted character, as well as the duration of the character in the Morse code.

Claims

one of the inputs of the AND element and the second element OR, to the other input of which connect the output of the first bit of the code converter, and the output of the second element OR is connected to one of the inputs of the output block, to the other input of which the output of the AND element is connected through the element "prohibition, to the input" Reading which is connected to the additional output of the clock generator. Such a device, based on the principle of intermediate coding of a ten-digit non-uniform code, allows using the shift register to memorize the insertion points to the dash and the ending points of the characters. The drawing shows a structural electrical circuit of the device. The device for generating the Morse code contains a serially connected information input unit 1, an encoder 2, a code converter 3, for example, a shift register, whose bit outputs, besides the first, through the first element OR 4 are connected to one of the inputs of the AND 5 element and the second element OR 6, to the other inputs of which the output of the first bit of the code converter 3 is connected, and the output of the second element OR 6 is connected to one of the inputs of the output block 7, to the other input of which the output of the AND 5 element is connected through the element "prohibition 8, to the input" the letter of which is connected to the output of the clock generator 9, combined with the input of the code converter 3, and to the input "readout" the additional output of the clock generator 9. The device operates as follows. Each character from block 1 is fed to an encoder 2, on the corresponding outputs of which pulses of a parallel non-uniform ten-bit code appear, which are written in parallel to the bits of the code converter 3. Thus, the bits of the code converter 3 are converted to a state of ones. From this moment on, the generator 9 with each clock cycle starts sequentially advancing the recorded information on the Converter 3, lowering by one digit the recorded numbers until it is completely released. From the output of the lower bit of the code converter 3, if there is a recorded unit in it, the latter will be read and sent to the element OR 6, which is the analyzer of the presence of code combinations, and to the element 5, which is the analyzer of the presence of the moment of inserts to form a dash. Similarly, from the outputs of the higher pressure bits of the code converter 3 if at least one of them has a recorded unit, the last will be read by the generator 9 and arrive through the OR 4 element into the AND 5 and OR 6 elements. The output signal of the OR 6 starts the output block 7 Forming the signal “punch. When the pulses from the element OR 4 and from the lower bit of the code converter 3 in the element 5 coincide, the signal from its output prohibits the writing of the unit to the element "prohibition 8 from generator 9, as a result, the output signal from the element" prohibition 8 when polling it from the input "read the subsequent impulse from the additional output of the generator 9 is absent, the output unit 7 remains in the state of pressing, which ensures the formation of an insert to form a dash. In the case of the absence of a prohibitive signal from element 5, the generator 9, at the input “record, writes a unit to the element“ prohibition 8, and at the input “reads it; the next and the pulse reads it, resulting in output block 7 from the element“ prohibition 8 ” “Squeeze. Thus, the formation of a combination in the presence of information in the code converter 3 is machined with the first pulse from generator 9 from its output (at the input “writing to the element“ prohibition B ”) and ends with the first pulse, from generator 9 from the additional output (at the input“ reading the element "prohibition 8) after the code-converter 3 release; 3.
