Изобретение относитс к электросв зи.The invention relates to telecommunications.

Известен формирователь кода Морзе по авт. св. № 331498, содержащий дешифратор , комбинатор, сдвигающий регистр, формирователь начала и конца знака формирователь временных интервалов с подключенным к нему генератором тактовых импульсов и выходной триггер.Known shaper Morse code on author. St. No. 331498, containing a decoder, a combinator, a shift register, a shaper of the beginning and an end of a character, a shaper of time intervals with a clock generator connected to it and an output trigger.

Между дешифратором и выходным триггером включены последовательно комбинатор предварительного преобразовани дешифрованного кода и дешифровани комбинации кода Морзе и конца знака на , соответствующих выходах, сдвигающий регистр , входы которого соединены с выходами кода Морзе комбинатора, формирователь начала и конца знака, входы которого соединены поразр дно с выходами конца знака комбинатора, формировател временных интервалов, сх)единенный с выходами сдвигающего регистра и формировател начала и конца знака, а также с входами входного триггера, входом опрос дешифратора, входом счетчика формировател начала и конца знака,входом сдвиг сдвигающего регистра.Between the decoder and the output trigger, the combinator of the preliminary conversion of the decrypted code and the decryption of the combination of Morse code and the end of the sign on the corresponding outputs, the shift register, whose inputs are connected to the outputs of the Morse code of the combinator, the driver of the beginning and end of the sign, whose inputs are connected to the outputs, are connected in series. the end of the sign of the combinator, the time interval former, cx) united with the outputs of the shift register and the former of the beginning and end of the sign, as well as with the inputs input trigger, input polling decoder input counter shaper beginning and end of the sign input shift shift register.

Однако в известном формирователе отсутствует возможность формировани информационных сигналов, т. е. точек в коде Морзе с определенной частотой следовани , необходимых при предварительной подстройке радиоприемной аппаратуры, что снижает достоверность передачи информации .However, in the well-known driver, there is no possibility of generating information signals, i.e. points in the Morse code with a certain tracking frequency, required for preliminary tuning of the receiving equipment, which reduces the reliability of information transmission.

Целью изобретени вл етс повышение достоверности передаваемой информации.The aim of the invention is to increase the reliability of the transmitted information.

Дл этого в формирователь введены управл емый ключ, триггер и переключатель , при этом выход тактового генератора через соответствующие контакты переключател соединен с входами триггера , выход которого через управл емый ключ подключен к второму входу дешифратора , а один из входов триггера - к дополнительному входу собирательного блокTo do this, a control key, a trigger and a switch are entered into the driver, and the clock generator output is connected to the trigger inputs through the corresponding contacts of the switch, the output of which is connected to the second input of the decoder via a control key, and one of the trigger inputs to the auxiliary input of the collecting unit

Claims

The Morse code shaper contains decoder 1, combinator 2, shift register 3, shaper 4 beginning and end of the character, shaper 5 time intervals with a generator of 6 clock pulses connected to it, output trigger 7. Shaper HaHakaf and the end of the character contains counter 8, a collective block 9 trigger 10; shaper 5 includes slots 11, 12, triggers 13-15, and slots 16-21. The Morse code shaper also includes a switch 22 and a trigger 23 and a control key 24. The shaper works as follows. When forming the information marks of the Morse code, the driver also works like the well-known driver, while the switch 22 is in the upper position, the trigger 23 is in the unit state and the control key 24 is in the mode allowing the signals to the decoder 1 to pass. in the mode of forming points (| the operator works as follows. When translating switch 22 to the lower position, trigger 2.3 moves to the zero state and blocks the signal of the next information sign, and the pulse clock pulse generator 6 through the collecting unit; 9 enters the input of trigger 10 and puts it in the zero state with a constant resolution of the coincidence element 11 at the corresponding input. When the next sign in the Morse code is completed, the subsequent pulse generator 6 P1, 18, g, 0 will set the output trigger 7 to the state of forming the current parcel (state O). The next pulse through the elements of coincidence 16, 18, 2O will set the output trigger 7 to the state of forming the pause (state 1) it. d, before moving the switch 22 to the upper position. In this case, the alternate clock pulse will set the trigger 23 to the enable state of the controlled key 24. When counter 8 is filled from its output, the pulse of the end of the character will set the trigger 10 to the state. Point formation stops. A subsequent pulse through a match element 12 will set the trigger & 13 and 14 to state 1 and O, respectively. The next pulse through the elements, coincidences 17, 18 and 20, will produce a request for the decoder 1 and the recording of the signals in the combinator 2, i.e. the formation of the sign of the Morse code will begin. Formula of invention Morse code shaper according to auth. St. No. 331498, characterized in that, in order to increase the reliability of the transmitted information, a control key, a trigger and a nef switch are entered into it, and the clock generator output is connected to the trigger inputs through the corresponding contacts of the switch, the output of which is connected to the second input through a control key descrambler, and one of the trigger inputs ..h to the auxiliary input of the collecting unit.
