(54) DEVICE FOR CONVERSION AND TRANSFER

INFORMATION

one

The invention relates to computing and can be used in digital computer output devices. .

A device for a communication line of digital equipment, which performs similar functions and contains a trigger, AND elements and HE / flj, is known.

However, the device is characterized by insufficient, protection against distortion of information.

A device for transmitting data, containing triggers and elements AND, OR, NOT 2},

The disadvantages of this device are low reliability of the transmitted information and the complexity of the device.

Closest to the present invention, there is a device for generating a message code comprising triggers, AND elements and a decoder Z.

The disadvantages of this device are significant hardware costs and the absence of synchronizing pulses at the output of the device, which complicates the monitoring of the correctness of the transmitted information.

Uejjb invention - simplification of the device.

The goal is achieved by the fact that. into a device for converting and transmitting information containing triggers and elements, And the first output of the first trigger is connected to the first information output of the device and through the first element I to the second input of the second trigger and the second output to the second information

0 to the output of the device AND through the second element AND to the first input of the second trigger, the outputs of which are connected to the corresponding inputs of the first trigger through the third and fourth

5 AND elements, the third trigger (anchor), the first and second AND-NOT elements, the first and second NOT elements and the OR element are entered, the first information input of the device is connected to the first input of the first AND-NOT element and through the First element is NOT. to the first input of the second element NAND, the second inputs of the first and second elements NAND are not combined and

5 are connected to the first output of the third trigger and the third synchronizing output of the device, and the outputs respectively to the second inputs of the first and second elements AND, the third

0 inputs of which are connected and connected via the second element NOT to the output of the OR element and to the second inputs of the third and fourth elements AND, the second, third, fourth and fifth clock inputs of the device are connected to the inputs of the OR element, and the third trigger,

Fig, 1 shows a functional diagram of the device; FIG. 2 is a time chart of the operation of the device.

The device contains information input 1, which is connected to the input of the first element AND-ffE 2 and through the first element NOT 3 to the B24 of the second element AND-NO 4, the second inputs of the elements AND-NO 2 and 4 are connected to the output of the third trigger 5. The outputs of the elements AND - NO 2 and 4 are connected via the Second 6 and first 7 elements And to the inputs of the second trigger 8, whose outputs through the third and fourth elements And 9 and 10 are connected to the inputs of the first trigger 11, Third 12 and fourth 13 clock inputs of the device are connected through the OR 14 element to the second element is NOT 15. Second 16 and fifth 17 clock inputs of the device are connected to the inputs of the third trigger 5,

A device for converting and transmitting information operates as follows.

In the initial state, the third trigger 5 trigger and the first 8 and second 11 triggers are in the zero state.

In the presence of a signal at the second clock input 16 of the device, the third trigger 5 of the binding is set to one and allows the first and second elements AND-NOT 2 and 4 to be fired. At the same time, the information transmitted to the device 1 arrives; Fig. 2 shows the transmission code of code 110011. If there is a unit at input 1, the first element AND-NOT 2 is triggered and prohibits the first element AND 7, and the second element 6 is activated and the second trigger 8 is set to one, With the arrival of the second the clock signal to the third input 12, the state of the second trigger 8 is rewritten into the first trigger 11. According to the third clock signal at the fifth input 17, the third trigger 5 is assigned to the zero state and prohibits the second and first AND-NOT elements 4 and 2, while the second trigger 8 mouth is brought into the state opposite to the first trigger 11, through the second and first elements 6 and 7 and with the arrival of the fourth clock signal on the fourth input 13 this state is rewritten into the first trigger 11, C

the arrival of the next informational signal 1 device works in a similar way. If the value of the next information bit is equal to O, the state of the second trigger 8

 on the first clock signal 12 does not change (remains in the zero state) and thus the phase change of the transmitted information occurs on the informational first 18 and second 19 outputs of the device. With the arrival of the next informational signal O the change of the Phase does not occur. If there is 1 in the next information bit, the phase of the transmitted information changes again.

5 formations.

The information signals from the first 18 and second 19 outputs are accompanied by the clock pulses generated by the third trigger 5,

0 which are used in reception to distinguish the phase of transmitted information,

Thus, the use of the proposed device provides

5 reliable information transfer to

line of communication due to the use of phase coding and tracking. information signals and, moreover, the proposed

Q transmission device is simplified.
