The first block of multiplexers 3 (see FIG. 3) contains a multiplexer 18.1-18.N whose address inputs form the second input of the block of multiplexers, the outputs of the multiplexers form the common output of the block, and the information inputs of the multiplexers form the first input of the block, and the first information input of each multiplexer is connected with information inputs of each previous multiplex. litter with a shift of one bit

The match block contains N elements AND 19.1-19..N.

The second block of multiplexers contains N parallel stages 20.1-20.N, each of which includes a multiplexer 21, two elements 2I (22, 23), element 2 OR 24 and switch 25, and the information inputs of multiplexers 21 of all stages are connected in parallel and constitute the first input multiplexer unit, the address inputs of multiplexers 21 of all stages form the second input of the unit of multiplexers 21. the direct and inverse outputs of each multiplexer 21 are connected respectively to the first inputs of the first 22 and second 23 elements 2I, the second inputs of the cat are connected respectively to the first and second outputs of the switch 25, the input of which is connected to the common bus 26, the outputs of the elements 2I 22 and 23 are connected to the inputs of the element 2 OR 24, the output of which is the output of the cascade and, together with the outputs of other stages, form the common output of the multiplexer unit .

The device operates as follows,

The first distributor 1 generates symmetrical pulses of the same duration, phase shifted relative to each other by p 360 ° / N. These pulses are simultaneously fed to the first inputs of Coincidence 4 and the first block of multiplexers 3. Depending on the code signal of the second distributor 2, pulses appear in the outputs of the first block of multiplexers 3 by (Q (N -1) “h) regarding first entry

multiplexers. These pulses are compared in Coincidence block 4 and fed to the first input of the second block of multiplexers 6. Depending on the code coming from the output of the third distributor 5, the address inputs of the multiplexers 21 of block b and their direct and inverse outputs show signals passing through the elements 2I 22, 23 to the input of the element 2 OR 24.

Depending on the position of the switch 25, at the outputs of the second block of multiplexers 6 pulses appear with

duration and N p (in position A)

and with a duration of Ј 4N-1) Ф (in position B). Thus, depending on the code of the second distributor and the position of switch 25, it is possible to obtain the number of pulses with different

with a duration of ti - (N-1) p, the number of combinations in terms of pulse duration is NN.

Depending on the code of the third distributor, 2 combinations can be obtained from the pulse train.

In general, using the second 2 and third 5 valves and the position of switch 25, 2N NN switching combinations are obtained.

In this case, the second 2 and third 5 distributors can operate both in manual and automatic modes (see, Fig. 2).

1. In manual mode, the switch 9 is in the open state,

2. In automatic mode, the switch 9 is in the closed state.

In the manual mode of operation, the codes at the outputs of the counter 15 (see FIG. 2) depend on the switch 17, i.e. at the initial moment of time, when the switch 17 is installed on any output of the decoder 16, at the output of the element 13, as well as at its input, there is a signal with a logic level 1. This signal goes to the second input of the element 12. At the output of the element 12, the pulses of the master oscillator 7 and they pass through element 14 to the counting input of counter 15. When a code corresponding to the position number of switch 17 appears at the output of counter 15, a signal with a logic level O appears at the corresponding output of decoder 16.

In this case, regardless of what signal level is at the first input of element 2I 12, a signal with a logic level O appears at its output and counter 15 stores a code corresponding to the position of switch 17. All other stages also work.

In automatic operation, at the second input of cascades 10.1-10.N there is a signal with logic level 1. Moreover, regardless of the level on the shared bus of switch 17, at the output of element 17, the signal corresponds to logic level O, and the level at the output Step 11 is determined by the level of the signal supplied to the first input of the cascades, i.e. the state of the counters 15 changes automatically when pulses are received from the second output of the first distributor 1

5 (the second output of the first distributor is its Nth output).

In automatic mode, the switching cycle is repeated through N pulses supplied to the input of the first stages

0 of blocks 2 and 5. With the help of the second distributor 2, the pulse duration at the output of the Match 4 unit is selected, and with the help of the third distributor 5 (see Fig. 1), the switching sequence at the output of Block 6 is selected.
