The invention relates to automation and computing and may. be used in devices for feeding pulses coming in through several independent channels.

The purpose of the invention is to increase reliability by simplifying the device.

FIG. 1 shows an electrical functional diagram of the device; in fig. 2 - time diagram of the operation of the device (in the version of four channels).

The device contains inputs 1.1-1.p devices, triggers 2.1-2.p, elements I.Zs1-3.p, one-shot 4 4.P, element OR 5, generator 6 pulses And, output 7 devices.

from the generator 6 pulses at the signal input of the one-shot 4.1, the output of the one-shot 4.1 appears

the impulse arriving at the R-input of the trigger 2.1 and setting it in the initial state. In addition, the pulse from the output of the one-shot 4.1 goes to the input of the element OR 5, from the output of which it goes to the output 7.

When simultaneously receiving pulses on two tires, for example, 1.1-1.2, the corresponding triggers 2.1 and 2.2 are set to one

condition. In this case, the signal O from the inverse output of the trigger 2 channel with a lower number closes the elements AND 3.1-3.3 of the remaining channels. After the return of the trigger 2.1 to the original

V-connected to the C-inputs of the trigger 2C 1-2.p, D-inputs of which are connected to the bus log. 1, and the R-inputs are respectively connected to the outputs of single-oscillators 4.1–4. An appropriate input is the output 7 of the device. The output of the generator 6 pulses is connected to the signal inputs of single-vibrators 4.1-4. P. Direct trigger output 2.1 is connected to the enable input, one-shot 4.1. The direct outputs of the flip-flops 2.2-2.P are respectively connected to the first inputs of the AND 3.1-3, p-1 elements, the outputs of which are connected to the enabling inputs of the single-oscillators -4.2-4.P. The inverse output of each trigger 2.1-2.p-1 is connected to the corresponding inputs {by the inputs of the elements 3.1-3.p-1. The device can be implemented, for example, on a 564 series chip.

The device operates as follows (in the version of four channels).

The frequency of the generator is 6 pulses, n times higher than the maximum frequency of the input pulses. In the initial state, the first inputs of the single vibrators 4.1–4.4 contain zero signal levels.

When a pulse arrives at any of the device input buses (Fig. 1), for example, at bus 1.1, the corresponding trigger 2.1 is set to one state. Since after installing the trigger 2.1 on. the enable input of the one-shot 4.1, a level-1 signal appears, and by the decay of the clockwise pulse, I get 40

the input element AND 3.1 and the signal 1 from the output of the trigger 2.2, arriving at the first input of the element AND 3.1, appears at its output. Further, the operation of the second channel is similar to the operation of the first channel.

When pulses are simultaneously received at all four inputs of the device, all input triggers 2.1-2.4 are set to one. The signal from the inverse trigger output 2.1 closes the elements And 3.1-3.3 of the second, third and fourth channels. The signal from the inverse output of the trigger 2.2 closes the elements And 3.2, 3.3 of the third and fourth channels. The signal from the inverse output of the trigger 2.3 closes the element And 3.3 of the fourth channel. Since the permitting input of the one-shot 4.1 is the enable signal, then by decreasing the clock pulse at the signal input of the one-shot 4.1, the first channel fulfills the effect on the input pulse in the indicated manner.

After the elements entering the first channel of the device return to the initial state, on all inputs of the element 3.1 3.1, the resolving potentials and on the decline of the clock pulse to the signal input of the one-vibrator 4.2, the elements of the second channel work out the input signal in accordance with the indicated algorithm.

After the elements of the second channel return to the initial state, the permissive state is removed from all the inputs of the third channel element 3.2 of the third channel from the second channel.

the input element AND 3.1 and the signal 1 from the output of the trigger 2.2, arriving at the first input of the element AND 3.1, appears at its output. Further, the operation of the second channel is similar to the operation of the first channel.

When pulses are simultaneously received at all four inputs of the device, all input triggers 2.1-2.4 are set to one. The signal from the inverse trigger output 2.1 closes the elements And 3.1-3.3 of the second, third and fourth channels. The signal from the inverse output of the trigger 2.2 closes the elements And 3.2, 3.3 of the third and fourth channels. The signal from the inverse output of the trigger 2.3 closes the element And 3.3 of the fourth channel. Since the permitting input of the one-shot 4.1 is the enable signal, then by decreasing the clock pulse at the signal input of the one-shot 4.1, the first channel fulfills the effect on the input pulse in the indicated manner.

After the elements entering the first channel of the device return to the initial state, on all inputs of the element 3.1 3.1, the resolving potentials and on the decline of the clock pulse to the signal input of the one-vibrator 4.2, the elements of the second channel work out the input signal in accordance with the indicated algorithm.

After the elements of the second channel have returned to the initial state, the resolving potentials are present at all inputs of the third channel element 3.2 of the third channel. In this case, in the third channel, a third output and a fans are formed.

After the elements of the third channel return to the initial state, the resolving potentials turn out to be at all inputs of the fourth channel element And 3.3 of the fourth channel. As a result, a fourth output pulse is generated. Thus, four impulses are formed on the output bus 7 in this case.
