 Traps 3. The number of dynamic traps filled with domains is equal to the number of CMD that arrived through the main platoon channels, but does not exceed the threshold value specified by the total number of dynamic traps, since the domains left after filling the dynamic traps along the main output channel 8 are advanced to the annihilator where they are destroyed. Depending on the number of domains that entered the main data input channel 6, the higher dynamic trap 3, the state of which determines the value of the implemented threshold function, the CMD is either present (if the total number of received domains exceeds the threshold value) or is absent ( otherwise, it identifies the single and zero values of the threshold function, respectively. Exciting the conductor application of the domain switch 11, outputting the CMD of the result of the implemented threshold function to the additional output channel 10 of the CMD advance (position 20).

If the implemented threshold function contains a positive weight that is different from the unit, the CMD corresponding to the logical variable goes through an additional input channel 13 to the junior dynamic trap 3 and then to the input of the replicator 12. The required value of the weight coefficient is obtained by dividing the incoming dynamic trap CMD required number of times, sending current pulses 12 to the replicator bus. In this case, the initial CMD remains in the junior dynamic trap, and the first, second, etc. its copies, advanced along the additional input channel, successively fill the dynamic traps 3. Then the remaining dynamic traps are filled with 3 domains, received into the main input channels, and the higher dynamic trap 3 is polled by outputting the data center switch 11 to the additional output channel 10 promotion of CVP. The controlled change of the trigger threshold is achieved by inputting an additional input channel to the lower dynamic domain trap (logical 1) and dividing it when it feeds the data input channel and current preferential channels to the CMD bus 12 replicator. At the same time, the input of the CMD and each subsequent division reduces the threshold of the threshold element by one. / 5

cylindrical magnetic domains, the additional channels of the preferred cylindrical magnetic domains being interconnected with the corresponding dynamic traps of the cylindrical magnetic domains and the additional data input channel connected to the first output of the replicator, the input and second output of which are interconnected with the lower dynamic trap of the cylindrical magnetic domains, which is connected to an additional input channel.

Thus, by varying the number of current pulses supplied to the replicator 12 1 of the SCCH, it is possible to widely change the value of the threshold or the weighting factor of the proposed threshold element.
