The pulse outputs of the distributor 1 pulses from the first to the K-th (where K is the number of input information buses of positive weight) are connected to the control inputs of the multiplexer 2, and its pulse outputs from the first to the 1st (where I is the number of information buses with weights) are connected to the inputs of multiplexer 3, the information inputs of multiplexer 2 are connected to the input information buses 10 of positive weight, and the information inputs of multiplexer 3 are connected to the input information folders 11 of negative weight. The outputs of multiplexers 2 and 3 are connected to the first and second inputs of switch 4, the outputs of which are connected to the information inputs of a controlled generator of 7 pulse bursts, the control inputs of which are connected to potential outputs of the bits of the distributor 1 pulses from the first to n .-go (where n, 2} is the largest of the numbers K and I), the first output with the summing counting input of the accumulator 6 5 the second output - with the subtracting 50 counting input of the storage device 6, the blocking output - with the first input of the element And 9 , and the counting input - with the output of the general ora 8 clock pulses and the second input of the AND gate 9, output 55 of which is connected to the counting input of the pulse distributor 1, the output is connected to the accumulator 6 infor25

trigger input 5, connected to the write enable input with (n + 1) th output of pulse distributor 1, (n + 2) -th output of which is connected to the reset input of accumulator 6 and controlled generator of 7 pulse bursts.

The threshold element works as follows 1 / k) in the first way.

In the initial state, the accumulator 65, the adjustable generator, 7 pulse packets, the trigger 5, and the ring distributor 1 of the pulses are reset. At the same time, a zero code is recorded in trigger 5 and in control generator 7, In the ring distributor 1 of pulses, the last (n + 2) -th discharge is in the unit state, and at the blocking output of the controlled generator 7 there is a (single) potential . In drive 6, the code of the number q. + I is written.

As the clock pulses from the generator 8 output through element I 9 to the counting input of the pulse distributor 1, the resolving (unit) potentials (signals) sequentially appear on the pulse and potential outputs of the bit distributor 1., starting from the first ,. Moreover, upon receipt of the 1st clock pulse, the (single) signals appear on the i-M pulse output of the distributor 1 during the duration of the clock pulse and on the i-th potential output during the duration of the clock pulse and subsequent break until the next clock pulse.

When a resolving potential appears at the iM output of the distributor 1, connected to the inputs of multiplexers 2 and 3, it allows the passage, to their outputs, of the signal from the i-th input bus of a positive weight and the i-th input bus of a negative weight, respectively, which enter the inputs of the commuter 4.

If there is a unit potential on the i-th input bus of a positive weight, and a zero (or) on the i-th input bus of a negative weight, then a single signal (potential) passes to the first output of the switch 4, If there is a zero potential on the i-th input bus of a positive weight (or i K), and on the i-th input bus of negative weight

then one potential passes to the third output of switch 4. If there is a single potential on ix input buses of positive and negative weight, then it passes to the second output of switch 4. A single potential takes place at the outputs of switch 4 only for the duration of the clock pulse If there are zero and positive weights on the ix input buses, then the unit potentials do not appear at the outputs of switch 4. If at one of the outputs of Switch 4 a single potential appears, it enters one of the information inputs of the controlled generator 7, initiating it. At the same time, a single potential arrives at the i-th control input of the controlled generator 7. In this case, the controlled pulse generator generates a pulse train at one of its outputs (coinciding with the pauses between clock pulses). Moreover, in the case when a single signal arrives at the information input from the first output of the switch 4, a bundle of pulses at the output connected to the summing counting input of accumulator 6 is driven, in the case when a single signal (potential) to the information input comes from the third output of the switch 4, a bundle of p / uJ / pulses is generated at the output, coupled with a subtractive counting input of the accumulator 6, in the case where a single signal to the information input comes from the second switch v 4, a bundle of p fuJ is formed. - {i I pulses at the output, connected with summing counting input of accumulator 6 at i) kJji and with subtracting counting input of accumulator 6 at cJ-luJ. I. In the case of 1x). IUL) pulses are not generated at the output of the controlled generator 7, since a single signal is not received at the control input.

At the time of initiation of the controlled oscillator 6, a signal from the output to the switching switch 4 at its blocking output appears to inhibit (zero) potential, which enters the input of the element I 9, prohibiting further passage of the clock pulses to the input of the distributor 1 pulses

for the entire operation of the controlled generator 7.

And the control generator 7 is fed to the counting inputs of accumulator 6. When a pulse arrives at the summing counting input, a unit is added to the contents of the accumulator, and when the {-gpulse arrives at the subtracting counting input, one is subtracted from the accumulator.

At the end of the cycle of operation of the controlled generator 7 (after the formation of the pack and the pulses) in the pause between the clock pulses after appearing at one of the outputs of the latter and myca5 the controlled generator 7 returns to its initial state; at the same time, at its blocking output, a permitting (unit Hbrii) potential appears, and the next total clock pulse passes to the countersign of the distributor of 1 pulses.

The threshold element operates as it does before polling all input psn, after which on (d + 1) th also the output from (n + 1) th dispenser 1 of the distributor 1 is fed to the ramp input of trigger 5, which then records the signal - cash of the accumulator output. b. At the output of the accumulator, 6 is formed unit to f, i
