the counter 37 and the selector .38 performed similarly to the selector 31, the Elo 1 record contains a pulse shaper 39 and a single-vibrator 40 and 41, the Comparator 11 is executed on the trigger 42 and the delay element 43 is delays. Similarly, the block 10 is compared to the trigger 44 and the delay element 45.

The device works as follows

It is reset to the initial state by a signal from input 4, which launches the one-shot 41. A pulse formed by the one-shot 41 with a duration longer than the period TO of the circulation of elements 13-15, locks the formers 17 and 18, which blocks the circulation circuit. The element from the lash 16, formers 17 and 18, the elements 19 and 20 of the trigger 23s, the element 24 for the delay and the amplifier 25. At the outputs of the elements 13-15 is set to logical. In the absence of pulses at the output of the element 13, the one-vibrator 29 is in steady state with logical level 1 on output Logic O is installed at the output of the one-shot 30, which blocks the information inputs of the selectors 34 and 35. In the initial state, the input stream coming from input 2 to block 1 is blocked by the shaper 39. The voltage from the source 26 comes to the second inputs of the elements 19 and 20 sets the threshold for capturing. From the outputs of the distributor 7 to the inputs of the elements 13-15 in-phase microwave signal with a period that modulates the levels of the exposed thresholds of the elements 19 and 20.

. The recording of the pulse flow from the input 2 (fig. 2a) to the elements 13-15 is carried out by the signal, which is fed to the input 3 (fig, 26) and starts the one-shot 40, the output signal of which (figv) opens at time t ,, T (j- T, - shaper 39 ". As a result, at the output of block 1, the information stream of standard pulses (figlg) of duration, formed by shaper 39, appears

where N is the number of memory elements (for the device in figure 1) ;.

K is the smallest of the numbers 1,2 ..., provided by the speed of the former 39. These pulses arrive at the input of the partitioned delay line 5, which consists of (N-1) identical elements with a delay on each Element TJ./N, and on the first the input element is 10 1 a 13, from where through the element OR 16

recorded in the circuit of the element 13. Similarly, the recording of the delayed pulse sequences in the circuits 15 of the elements 14 and 15. The first recorded pulse from the output of the element 13 (Fig. 2g) through the open element And 28 starts the one-shot 29 (Fig. 2h), - which closes the element AND 28 before returning to the output of the element 13 of the first recorded pulse, which restarts the one-shot 29, and the process repeats (Fig. 2h).

The flow of pulses in element 5 is stored as a result of continuous circulation in the circulation circuit with a period, where n is the synchronization ratio of element 13. In stationary storage mode, the duration (tn) of pulses in the stream is equal to an integer number of periods Tf This is achieved by the fact that the flow of pulses regenerated as a result of the circulation at the second input of the element OR 16 is divided into two streams, the first of which is formed, at the output of the former 17 (fig.2d) and the pulses which are phased with the edges of the pulses incoming x to the element OR 16, and the second is formed at the output of the former 18 (Fig. 2e), the pulses in it are phased with their spins. These streams arrive at elements 19 and 20, respectively, where the synchronization of the differences in each pulse of the flow with the phase of the microwave signal (the synchronization phase) is fixed within the period T. The merging of the two streams is carried out by trigger 23, the fronts and decays of the pulses at the output of which is initiated. They are driven by pulses from the outputs of threshold elements 19 and 20, respectively. Due to the fact that the phases of these pulses are associated with the corresponding synchronization, the pulse duration at the output of the trigger 123 coincides with the integer number of the period-microwave signal.

TC periods are equal and the intervals between pulses. The flow of pulses from the output of the trigger 23 (Fig. 2g) is fed to the second input of the element OR 16, and the circulation process is repeated. There is storage of the stream recorded in element 13 from the output of block 1; recording. Since each of the pulses in element 13 is phased with syncro. This leads to a distortion at the output of the element 13 of the duration of the time intervals corresponding to the formed block 1. To increase the accuracy of the device at the recording stage, the position code containing the phase information of the microwave is stored and then stored in the memory elements 13-15. signal, corresponding to the moment of arrival at the output of block 1 of each pulse in the stream. This allows for reading to clarify the phase of arrival of each pulse within the period T. The microwave signal and to correct the duration of the intervals read from the output of the element 13.

The mode of formation of the device positional code.

Without loss of generality, the period T c can be understood as the time interval between the nearest points of the transition of the microwave sinusoid through zero (Fig. 2a), in which its first derivatives are positive. Recordable flow pulse is fed to the input element 13 (fig.2b) and then successively through the time T / N / Ha inputs of elements 14 (fig.2b) and 15 (fig.2g) (for the device in figure 1.). If the front of the pulse at the input of the element 1-3 coincides in time with the segment I of a certain period T, the microwave signal, where

this period coincides with the fronts of pulses arriving at the memory elements with numbers N + 1-j and obtained as a result of reproduction of the recorded pulse by the delay line 9 (the memory element numbers should be counted from the element connected to the first output of the partitioned delay line 9 ). The pulses at the inputs of the memory elements with the numbers i N + 2-j, N are already combined with the next period of the microwave signal (Fig. 2d). Each pulse is recorded in the corresponding memory element.

Due to the synchronization of the first threshold elements 19 of the pulse fronts in the memory elements with

Frames 1, N + 1-j turn out to be rigidly phased with the synchronization phase of the same period of the microwave signal (Fig. 2e, e) and in the storage mode are repeated in phase at the outputs of these memory elements. In phase, but shifted by a period T., the pulse fronts at the outputs of the elements are repeated.

memory numbers N + 2-j, N (Fig. 2g). If the pulses at the outputs of these elements with numbers from 1 to N are in-phase, then we assume that the shift is caused by the output of the dummy (N + 1) -ro memory element. The number V N + 2-j of the element on which the described shift occurs may be coded with the code for the number j of segment 1. Connection) and j is given by the formula

which allows for the number to clarify, within the period Tc to the discrete T5./N, the phase of the initial pulse arriving at the input of element 13.

Additional refinement of the phase of the recorded pulse with an accuracy of Tc./2N discrete is achieved by analyzing the duration t, the pulse at the output of the (1-1) th memory element. Since the front of the pulse arriving at the memory element with the number (-0-1) is always aligned with the first or second half of segment I., its decrease according to (1) and (2) coincides, respectively, with the subsequent Km or ( K + 1) -th period of the microwave signal. Consequently, in the storage mode, the decay of the pulse circulating in the (JOM memory element) will be associated with the synchronization phase of the K-th or (K + 1) -th period of the microwave signal (the synchronization of the pulse decay with the phase of the microwave signal occurs at the second threshold element . (V-1) th memory element. As a result, when the front is aligned with the first half of segment I. (Fig. Ze.1), and 1). (K + 1) Tc, when the front is combined with the second half segment i

J7 (FIG

Ze.2). The duration of the pulses on the codes of all other memory elements is always equal to KTj, Since the fronts of the original and corresponding to it multiplied

impulses coincide with caustic and those i ....

by the halves of all segments into which the period is divided, this allows to specify up to half of segment 1 by the pulse duration at the output of the memory segment with number (), i.e. up to the discrete Tc / 2N, the phase of the original pulse recorded in the memory element 13,

: Similarly, a position code is generated for each pulse output after the output of the recording unit,; The restoration of the duration of the intervals of the input stream according to the information recorded in the memory elements consists in allocating and transforming time intervals in accordance with the read algorithm entered into the imaging unit 9. This is done using the read unit 8, the former 9, the converter 12, the comparator 11 and block 10 comparison.

The signal from input 27 starts the reading algorithm, organized in the form of reading cycles of Time intervals,

Any pulse stored in memory elements 13–15, is uniquely determined by a pair of numbers (), where i is the number of the memory element in which it is recorded, and e is its sequence number in this memory element relative to to the reference pulse generated at the output of the selector 31.

The read cycle begins with the formation in the shaper 9 of two pairs of numbers (1, e) and (1, e), which arrive at the address input of block 8 and determine the start and stop pulses, respectively, limiting the selection interval from the stream stored in memory element 13. The value goes to the address input of the multiplexer 36, and the value e: to the D input of the counter 37. The values in the selector 35 are similarly distributed. Next, the imaging unit 9 generates an unlock signal on the control input of the converter 12, as well as a pulse signal ( Fig. 2i), which is supplied to the installation input of the block 8, will act on the trigger 33 (Fig. 2k), opening, in its

turn S, element And 32. The impulse is single, the vibrator 29 through element 32 resets the trigger 33 (FIG. 2k). In this case, the element 32 is closed, and at the output of the selector 31 a reference pulse is formed (FIG. 2), linked to the start of circulation in the memory element. 13. This pulse triggers the one-shot 30, the control signal of which duration T (Fig. 2m) is fed to the control inputs of the selector 34 and 35. A start-pulse corresponding to the value (1, еi) is outputted at the output of the selector 34 (FIG. .2n) during the action of a one-shot pulse .30.

Similarly, a stop pulse is output from the output of the selector 35.,

The selector 34 operates as follows.

The code 1 is set at the address input of the multiplexer 36, and the value 37 is recorded in the counter 37 by a pulse from the setup input of block 8. By the signal of the one-shot 30, the time | Current of the 1st memory element from the output of the multiplexer 36 goes to the counter-37 and the selector 38. When counting to one, the counter 37 will set the selector 38, at the output of which a pulse with the number e is selected. The time between the allocated start5

and the stop pulses are converted by the converter 12 into a code which is fed to the imaging unit 9, after which the converter 12 is blocked until the next read cycle.

The analysis of the phase of the start pulse relative to the microwave signal is carried out during the read cycle in (N) steps. step (, N) shaper 9 forms two pairs of numbers; (1je- |) and (1, e), arriving at the address input of block 8, which, like the one described above, selects a start-pulse at its first output (1, e), and at the second output - start-sh-shulse (ije ). The pulse from the first output of block 8 is fed to the first input of block 10 of comparison and then through element 45 with a delay to the S input of the trigger 44. The pulse from the second output of block 8 goes to the e R input of the trigger 44, and if it is delayed with respect to the pulse at the first output of block 8, then the trigger 44 is set to the state O, if there is no delay, then the state of the trigger is 1. The impulse from the second output. Yes, block 8 also enters the R-input and through element 43 with a delay

The states of flip-flops 42 and 44 are fixed at each step of shaper 9. According to the sequence of states of flip-flop 44, shaper 9 assigns the number-O of the memory element on which the first shift of the compared pulses occurs, which allows according to (-2) and (3 ) clarify the phase of the start-pulse to the accuracy of the TC / N discrete. Further refinement of the phase of the start pulse with an accuracy of Tc / 2N discrete occurs as a result of analyzing the states of the trigger 42 for the output pulse (-O-D-ro memory element.

Similarly, the start-impulse analyzes the phase of the stop-impulse relative to the microwave signal.

This completes one read cycle and the driver 9 proceeds to the next cycle. Number read cycles equals the number of time slots recorded in the element 13. If you try to read the time interval following the last recorded in element 13, the converter 12 overflows;

The generator shaper 9 fixes the end of all read cycles.

The operation of the device ends there.

The technical efficiency of the proposed device is determined by the exclusion of half of the memory elements and a twofold reduction of the partitioned delay line, which ensures a reduction in the device dimensions, simplification and greater manufacturability in manufacturing.
