The pulse with the sequence number P comes from the output of the delay element 23 to the signal input of the selector 44 and through the elements I 45 and 47 to its outputs, and through the element I 46 to the R

as a result of the arrival of the trigger pulse from the output of the selector 44 to the input of the TO element in the closed feedback loop of the generator 39 formed by the elements 40-43, a positive impulse begins to pulsate. The period T of circulation is selected using the element 42 of the delay

Generator 51 with a circulation period T operates in a similar manner.

The interaction of the pulse circulating in the closed loop of each of the generators 16, 39 and 51 with the microwave signal at the threshold of the corresponding tunnel diode results in the synchronization of the pulse generators with an external microwave signal. As a result, the impulse of each of the generators is 16,

39 and 51 are rigidly connected with the corresponding 20 t — t — t pulse per

Due to the synchronization phase shift relative to each other by the value ---, which is due to the phase shifts of the microwave signals at the inputs of the generators 16, 39 and 51, impulses arriving at each circulation cycle from the outputs of the generators 16, 39 and 51 (Fig. 26, - I and U) fia the main inputs of block 33 are shifted relative to each other by a large 21

the output of block 33 is selected from pulses that arrive at the additional input of this block from the first output of switch 24 (FIG. "2) and

Since the duration of the IMPULSE from the output of block 33 also enters the second installation input 30 of block 2 and through the elements OR 3 and 4 on TiKiTBf i.e. the inputs of counters 6 and 9. The output of the codes of numbers N and N summed up at the moment of time -; : -Mam 13 and 14. As a result. In the event, the phenomena are brought to each other, and the signal from its outputs returns all elements of the device to the initial state.

the pulse (4 in) at each of the inputs of the OR 34 element exceeds several times the period T of the microwave signal (T. 1 not), then these pulses overlap in time. At the output of the OR 34 element, each pulse of the circulation processes a total pulse (the result of superposition of the input pulses), the front of which advances the center of the input pulse stack by a fixed amount equal to

Y-Tj,. Compensation for this advance

effected by the pulse passing of the delay element 35.

After switching the switch 24, the counting of the pulses at the output of the former 22 continues in the counter 6. When their number reaches the value of PJ, the state of the counter 6 becomes equal to Zg, and at its output is 1 (Fig. 2k), which goes to the control the input of the block 33 and through the element OR 11 to the input of the download resolution of the counters 6 and 9. The signal from the output of the inverter 5 (Figure 2e)

blocks the element And /, and also the zlomes 21, 41 and the generator S1, which leads to a breakdown of the oscillations.

"At the next, after unblocking the element I 36, a pulse arrives at its signal input from the output of element 35, the latter passes to the input of the imaging unit 38 and a pulse is output at its output, which is fed to the output terminal 35 (Fig. 2n) and is pulses delayed relative to the input time T, where

The limitation on the part of the upper range of the delay range is determined primarily by the instability of the behavior of the microwave signal, which, in fact,

From the description of the operation of the device, it follows that the P, and pulse of the generator 16 45 are connected in synchronization mode with the synchronization phase 1 (synchronization phase 3) has uncertainty and is located in the center of a pack of 3 pulses counted at the output phase of these pulses. If the ratio of 50 P generators 16, 39, and 51 for each phase of the microwave signal, then this is due to the circulation cycle.

Consequently, a pulse with a non-predetermined input to the element 17 simultaneously with the trigger pulses at the inputs of the forming threshold elements of the generators 39 and 51. Since

The T- / 6 laziness at the input of the element OR 34 is always aligned with the center of the pack.

leads to the uncertainty of the delay of the pulse at the output of the device caused by the fluctuation of the length of time ((Fig.2), which forms 55 - pulses coming from the generators 16, 39 and 51 during each circulation cycle. The front of the pulse at the output

From the pulse sequence at the output of one of the generators 16, 39 or 51, operating in synchronization mode. To analyze this non-element, OR 34 leads the front of the central impulse of the stack at a fixed rate in FIG. 3 by 1 (FIG. 3) indicates the synchronization phase of the generator 16, which is realized when element 17 triggers from pulse P, within the period A, B, i.e. when the front of the P-th pulse- crosses the level of the modulated threshold within these limits. In numbers

In Cj, AjBj and B, Cj) respectively. Of the diagram in FIG. 3 it follows that when combining the beginning of the pulse

P, with area I, the operation of elements 17, 40 and the forming threshold element of generator 51 occurs within the period A, B,, A, B. and A, B ,, respectively. As a result impulbs

from generator 51, associated at subsequent circulation cycles with synchronization phase 4, has an uncertainty of Tj with respect to the triggering one. The & &, and is located in the center of the stack of 3 pulses, counted at the outputs of the generators 16, 39 and 51 during each circulation cycle. The generator pulse 39 is coupled to the synchronization phase 2 and is ahead by time

a pulse of the generator 51, and a pulse of the generator 16 is associated with the synchronization phase 1 and lags temporarily from the pulse of the generator 51. The timing diagram in FIG. 2 matches

this occasion.

Similarly, it can be shown that when combining the beginning of the P, -th pulse with region II (region III), the pulse generator 16 (generator 39)

The T- / 6 laziness at the input of the element OR 34 is always aligned with the center of the pack.

element OR 34 is ahead of the front of the central impulse of the pack on a fixed

some time, which is compensated for by the passage of the delay element 35. This allows the output pulse of the device to be aligned with the center of the stack in time. As a result, the delay uncertainty is T- / 6. So with a microwave frequency of 1 GHz, the delay uncertainty is

"166 PS.

An example of a specific implementation of a discrete delay device and a 1-pulse is considered for the case of using three pulse oscillators. Variants with an arbitrary number N of pulse generators are easily realized by analogy. The phase shift of the microwave signal at the threshold of the element of each subsequent generator relative to the previous one is chosen in this case, early 2 IT / N, the time of passage of element 35

N- 1 is set to (-) T, and

the uncertainty of the pulse delay is T (- / 2N, which is N times less than for the known device.
