Description

The invention relates to telegraphy, can be used in the training of radio telegraphs and is an improvement of the known generator according to the author. St. No. 1107318.

The purpose of the invention is to extend the functionality by forming an image of the characters of the generated characters.

The drawing shows a structural electrical circuit of the proposed automatic Morse code generator.

The automatic Morse code generator contains a noise generator 1, a counter 2 with a variable division factor, the first register 3 of memory, a block 4 installation of the counting coefficient, a distributor 5, a switch 6 sign cells, a program matrix 7, a combinator 8, an adder 9, a sign counter 10, initial setup block 11, pulse generator 12, pause duration combinator 13, interval counter 14, first AND unit 15, 16-digit encoder, multiplexer 17, program counter 18, second memory register 19, second And 20 element, encoder 21 characters, third register 2 2 memory, switch 23 characters, generator 24 characters and indicator 25.

The generator works as follows.

The noise generator 1 generates a colored stream of pulses. The received signal is applied to the clock inputs of the counter 2 with a variable division factor and the program counter 18. The counter ratio of the counter 2 with a variable division factor (N) can vary from 1 to 15. The counter ratio of the program counter 18 (M) varies from 1 to 16 Thus, it is possible to form up to 240 different equal-variable combinations from combinations of the state of counter 2 with variable division factor and program counter 1B. The number of characters in Morse code is limited and equal to 40. The counting coefficient of the counter 2 with a variable division factor is set depending on the size of the alphabet using the block 4 for setting the counting coefficient by applying to the installation inputs of the counter 2 with a variable division factor the corresponding potentials generated by second out5

dah block 4 set the coefficient of the account. The first outputs of the block 4 settings of the counting factor serve to limit the counting coefficient of the program counter 18. The first 3 and second 19 memory registers record and store for the character generation period of the code combinations of the counter 2 with a variable division factor and the program counter 18, respectively. The information is recorded in the first 3 and second 19 memory registers by a write pulse emitted from the output of the first element 15. The signal from the output of the first memory register 3 is fed into a parallel code to the distributor 5, which is a decoder. The distributor 5 has four inputs and fifteen outputs. When a combination appears at the inputs of the distributor 5, a signal corresponding to the logic level 1 appears at one of its outputs, at all the others - the logic level O. When the counting coefficient of the counter 2 with a variable division factor is limited, the number of outputs of the distributor 5, which can transferred to the state of logic 1. The signal from the outputs of the distributor 5 is fed to the switch 6 sign cells, where mechanically the outputs of the distributor 5 are connected with the corresponding signal nymi inputs program matrix 7. Thus is effected a change of volume of the alphabet. The signal from the output of the second register 19 of the memory in the parallel code goes to the second (control) inputs of the program matrix 7, which represents a multi-channel multiplexer, which has forty outputs. At the same time, changing the sign distribution law is performed by changing the number of combinations generated at the second inputs of the program matrix 7 by changing the counter ratio of the program counter 18 and the corresponding switching of the first signal inputs of the program matrix 7. At the same time, a resolution signal is generated at one of the forty outputs of the program matrix 7 corresponding to the logical level 1.

The appearance of the resolution signal at the i-M output of the program matrix 7 determines the generated sign. At the outputs of the combinator 8 and the encoder 16 od3 13, the resolution signal is received at a time. Depending on the sign generated, the six outputs of the combinator 8 generate one of ten code combinations corresponding to the length of the signs generated. At the same time, combinations of a 19-bit code corresponding to the shape of the generated characters are formed at the outputs of the encoder 16.

The pulse generator 12 operates in the autogeneration mode and produces clock pulses, the period TQ of which corresponds to the duration of the elementary premises of the points. These pulses arrive at the input of the sign counter 10 and simultaneously arrive at the first inputs of multiplexer 17, adder 9, first element 15, and. At the inputs of the first element 15 of code combination 100111, a recording pulse is formed at the output. When the combinations coincide at the outputs of the combinator 8 and the corresponding outputs of the bits of the sign counter 10, the output of the sign 9 appears at the output of the adder 9, which is gating and sets the sign counter 10 to the initial state, which determines the pause duration. To form five-digit groups, the signal from the output of the adder 9 is fed to the input of the counter 14 intervals, which serves to count the number of generated characters. The counting factor of the counter 14 intervals is 250, and at the first output the control signal is formed by dividing t

gating pulses with a counting factor equal to five, with a level corresponding to logical 1, and at the second output with a counting factor equal to 250, with a logic level of O. The signal from the first output of the counter 14 intervals goes to the input of the combinator 13 pauses duration For example, if the signal level corresponds to a logical O, a combination 100110 is formed at the output of the combinator 13 for a pause (for a pause, a duration of three points), and for a logic level of 1, a combination of 100100 (for a pause of five points). The duration of the pauses is regulated separately for different levels of the control signal within

The multiplexer 17 is designed to convert a parallel code at the output of the encoder 16 into a sequential code. The second (signal) inputs of the multiplexer 17 receive a signal from the outputs of the encoder 16. The inputs of the multiplexer 17 are polled by the sign counter 10 by forming the corresponding code combinations on the first (control) inputs of the multiplexer 17, while the first input of the multiplexer 17 corresponds to 5 binocular 101001. The input signal is fed to the first input of the second element I 20, the second input of which is supplied with a signal from the second output of the counter 14 intervals. When a signal at the second output of the counter appears 14, the signal intervals with a logic level O result in the formation of text. Simultaneously with the appearance of the resolution signal at the i-M output of the program matrix 7, the encoder of 21 characters forms a six-digit code combination defining the sequence number of the generated character in the alphabet, for example

These codewords are written in parallel in the third register 22 of the memory. The information is recorded and promoted in the latter by recording pulses from the output of the first element 15. In the register 22, the memory is recorded in a parallel form of at least a combination of two characters. A switch 23 characters serves to connect the generator inputs 24 characters to the outputs of memory register 22. . Depending on the outputs of the register 22 of the memory connected via the switch 23 characters on the input of the generator 24, the image is delayed in time relative to the end of the Morse character generation for the interval of 0,1,2,3, ... characters. When the generator receives 24 characters of the code combination of the number of the corresponding character, it generates an image signal arriving at indicator 25, on which a graphic symbol of the character appears.
