a number of delay elements 12, while doing so on the combined inputs of blocks 13. Of all the 13 blocks, those whose second inputs are high potential are triggered, which corresponds to the availability of information. The strobe pulse through the OR-NOT 2 element via the communication line 6 goes further to the combined inputs of elements AND 11. During the duration of this pulse, the passage of information pulses arriving at the first inputs of the elements 11 is allowed.

Information is transmitted through the first information channel by a strobe pulse received by the control of its input, and by the second information channel by the same pulse but delayed for a certain delay time. Information from the remaining channels 7 is transmitted by the same pulse, i.e., i.e. delayed by the delay time with respect to the previous one. Due to the alternate transmission of information from each channel 7, the total interference iiini transmission does not exceed the interference from one channel, which increases compared with the known device to increase the reliability of information transmission.

DEVICE FOR TRANSMISSION AND RECEIVING OF INFORMATION The invention relates to the field of computer engineering and can be used to transmit digital information between devices connected by wired communication lines. The aim of the invention is to increase the noise immunity by means of a temporary SU ,, 1322250 1 322250 separation. The device contains a control channel 1 containing an element 2 IPI-NOT, transmitting 3 and receiving 4 amplifiers, element NOT 5 and communication line 6. Information channels 7 contain a communication line 8, transmitting 9 and receiving 10 amplifiers, elements 11, delay elements 12, and a block 13 and elements 13 consisting of elements 14. When transmitting information, a pulse is received at the control input of the device, which alternately enters the inputs of the blocks 13 of each channel 7. Information from the corresponding information inputs through amplifiers and a communication line is fed to the elements And 11 and to the output of the device. The introduction of delay elements allows the temporary compaction of information. In this case, the total interference level does not exceed the interference level from one channel 7, which increases the noise immunity of the device. 1 ill.
