Description

The invention relates to a pulse technique and can be used in pulse signal processing systems.

The purpose of the invention is to expand the functionality by ensuring the formation of time intervals when the duration of the input pulses does not exceed twice the propagation delay time of the base element of the selected series of chips.

FIG. 1 shows an electrical functional diagram of the device; in fig. 2 - time diagrams, according to his work.

The time interval former contains the first input bus 1 connected to the first input of the first element OR 2 and the S input of the first trigger 3, whose R input is connected to the output of the second element OR 4, and the output to the first output bus 5 and the first input of the AND element 6, the second input of which is connected with the output of the second trigger 7 and the second output bus 8, and the output with the first input of the OR 4 element and the second input of the OR 2 element, the output of which is connected to the second input of the OR 4 element and the second input bus 9.

The device maintains operability 1 s when the duration of the input pulses does not exceed twice the delay time of the propagation of the base element of the selected series of chips.

At the exit of the device, counter. To the south of the output at which a useful time interval is formed, an interference pulse is generated, the duration of which is equal to four times the propagation delay of the base element of the series of microcircuits selected for use, so that it is necessary to impose restrictions on the usefulness of the time interval.

The device works as follows.

In the initial state, the output tires 5 and 8 have zero activity level. 1;: if at time t, (fig. 2a) p) I1pe.l pulse per spike 1, op, I act on S-BXO- of trigger 3, I take it to the second steady state. On npshe 5 starts

generate an output pulse (Fig. 2c). At time t, a pulse arrives at the input bus 9 (FIG. 26), which forms on the bus 8 the beginning of the interfering pulse

(Fig. 2d), and, acting through the OR element 4 on the R input of the trigger 3, finishes the formation of a useful pulse on the input bus 5. At the output of the element I 6, a high level of activity is first formed (Fig. 2d) and then, after the transition

trigger 3 to its original state, again a low level of activity. However, a high level of activity from the output of the AND 6 element will return to the initial state the trigger 7 after a certain period of time equal to

quadruple the propagation time of the base element of the selected, to the application of a series of circuits. In the case when the impulse arrives first in time on the input spike 9, the useful time interval is formed on the spike 8 (Fig. 2d), and along the path

At the end of this interval, H1ine 5 pairs are formed. Thus, the device forms time intervals on the output terminals 1 and 5, depending on which input 1 and 1 pulse came first.
