Description

The invention relates to telegraph communication, can be used in devices for transmitting information by a Morse code, and is an improvement of the invention according to the author. No. 1170626.

The aim of the invention is to eliminate the disappearance of the elements of the sign with an increase in the rate of formation of the Morse code.

The drawing shows the structural-electrical circuit of the electronic key of the Morse code.

The Morse code electronic key contains a clock generator 1, the first 2 and second 3 elements OR, the block 4 of forming the sign elements, the manipulator 5, the shifter 6 of the shift signal, the first block 7 and the second 8 blocks of memory, the block 4 of forming the sign elements contains triggers

points 9

and dash 10 and the element OR

11, and the first 7 and second 8 memory blocks contain the first 12 and second 13 elements OR, the shift register 14, the first 15 and second 16 elements I.

The electronic key of the Morse code works as follows.

In the initial state, the manipulator 5 is in the neutral position, the shift registers 1A and the trigger points 9 and the dash 10 are in the zero state, at the output of the first 7 and second 8 memory blocks, O, the shift registers 14 are in the code writing mode , at the output of the circuit - O.

When the manipulator 5 is transferred to the first position (the top one in the drawing), the signal from the manipulator 5 provides writing 1 to the first digit of the shift register 14 of the first memory block 7, and 1 appears at the output of the OR element 13, which translates the register 14 the shift to the shift mode and simultaneously through the STI element 2 starts the clock generator 1; the trigger of 9 points switches to one state; 1 output appears at the output, the leading edge of the output pulse is differentiated by the shift signal generator 6. Since at the first output of the shift register 14 1, the shift signal enters the input of the element AND 15 and further to the element OR 12, from the output of which enters the shift register 14 and shifts the previously recorded 1 from the first bit to the second. The first bit of the record

O and subsequent shift signals may arrive at the element OR 12 after the manipulator 5 is moved to the neutral or second position.

When translating the manipulator 5 into the second (lower in the drawing) position, the signal from the manipulator 5 through the second input of the element OR 3 similarly records 1 to the first bit of the shift register 14 of the second memory block 8, after which the manipulator 5 can be transferred to the next position, and the shift signal, formed at the moment of the end of the pause following the point, releases the second bit of the shift register 14 of the first memory block 7 and shifts 1 from the first bit of the shift register 14 of the second memory block 8 to the second bit dash transmission starts . If during the dash transfer time and the pause following it, the manipulator 5 is sequentially transferred to the first, and then again to the second position, then at the output of the first bit of the shift register 14 of the first memory block 7, after recording the point, 1, which goes to the first input of the OR element 3, the output of which, regardless of the position of the manipulator 5, is 1, which corresponds to the prohibition of recording information into the first bit of the shift register 14 of the second memory block 8 5. The prohibition of recording is removed from translation by the next sd pulse yoke 1 of the first discharge unit 7 of the first shift register memory 14 in the second discharge. Thereby a condition is provided

, t y Oh,

where t is the double stroke time of the manipulator 5;

1 - the duration of a point or pause i. the moment of the secondary transfer of the manipulator to the second position is no longer limited in time from below.

Using the electronic key of the Morse code allows you to reduce the transmission time of a certain amount of information, since the number of offsets in the transmission decreases, therefore, the time for their correction is not spent, which increases the average information transfer rate.
