Abstract

The invention relates to a technique of multichannel communication systems. The purpose of the invention is to improve noise immunity while reducing information delay. The device contains 1 frame former, frame converter 2, nonlinear distributor 3, combining unit 4, and in each channel phase comparator 5, shift register 6, switching unit 7 consisting of switch 8, switching element 9 and 10, and OR 11, E-I AND 12 and 14, trigger 13, start-stop shaper 15 recurrent combination of stuffing and shaper 16 write pulses. The goal is achieved by the introduction of a converter 2 and a distributor 3, with which a shortened frame signal transmission frame is formed, providing an increase in the speed of reading in each channel, which is equivalent to the introduction of an initial positive detuning of conjugate frequencies. The device according to claim 2 f-ly is characterized by the execution of a shaper 15. 1 cp f-ly, 3 ill.

Description

ra 18, which sets the start45 paratora. and to the input of the register entry is the value of the sensor 19 recurrent, corresponding to the number K,

For example, if, then the start (start) is the first position of the recurrence (for example, 1000 ... 0), if, tr is the second, if, TO m + 1 position The end of the recurrent sequence (stop) is a fixed combination, for example 111. ... 1, allocated by the decoder 20, which performs operations on the introduction of the ballast parcel. Thus, a recurrent shift is formed, the bit outputs of which are connected to the corresponding inputs of the switching, one of the outputs of the switching node is connected to the control 50 input of the start-stop driver of the recurrent combination of stuffing through the series-connected fifth element And, the trigger and the second element And, moreover, the output of the phaeocompressor is connected to another input of the first element I, which differs in that, in order to increase the stability of materials while reducing information delay,

shift, the outputs of the bits of which are connected to the corresponding inputs of the switching node, one of the outputs of the switching node is connected to the control input of the start-stop shaper of the recurrent combination of stuffing through the first element And, the trigger and the second element And, the output of the phase comparator connected to the other input of the first element And, which differs from the fact that, in order to increase the noise immunity while reducing the information delay,

These are the serially connected frame converter and nonlinear distributor, with each output. nonlinear distributor by keys to another input of the second element I and synchronization input of the start-stop driver of the recurrent combination of stuffing of the corresponding channel, additional output of the generator of the recurrent combination of stuffing in each of the channels and connected to another input of the trigger and to the control input of the switching node, the read input of which is connected to the second input of the phase comparator and the corresponding channel output of the frame converter, to the input of which the output of the frame generator is connected in, wherein the other output switching node is connected to another

the corresponding input of the union node. 2, Device according to claim 1, characterized in that the start-stop driver of the recurrent combination of stuffing is made in the form of serially connected pulse counter, decoder of the beginning of the stuffing combination, recurrent sensor and decoder of the end of the stuffing combination, and the sync input of the recurrent sensor is connected to the corresponding pulse counter input and is the synchronization input of the start-stop driver of the recurrent combination of stuffing, the control input of which is the control input counter First and second outputs which are recurrence of the sensor output, and the output end of the combined stuffing decoder,
