The invention relates to a pulse technique, can be used in digital computing, in devices of automation and telemechanics for separating the first and any other pulse from a pack or from a continuous pulse sequence and is an improvement to the author. St. No. 1001454.

The purpose of the invention is to expand the functionality by selecting the first pulse.

The drawing shows an electrical functional circuit diagram of the device.

The device contains a subtracting counter 1, the first 2, the second 3 and the third 4 triggers, the first 5 and the second 6 elements of the match, the first element 7 NOT, the bus 8 of the control signal, the bus 9 of the pulse train, the output bus 10, the bus 11 of the code, the third element 12, the fourth trigger 13 and the output bus 14 of the first pulse, while the inverted output of the second trigger 3 is connected to the R input of the first trigger 2, the counting input of which is connected to the control signal bus 8, and the forward output is connected to the R inputs of the third and fourth 13 triggers and second in the first 5 and third 12 match elements, the first input of the first match element 5 are connected to the output of the element 7 NOT and the counting input of the subtracting counter 1, and the output is connected to the first input of the third match element 12 and the S input of the third trigger 4, direct output which is connected to the input of the entry of the code of the deducting counter 1, to the third input of the third match 12 and to the R input of the second trigger 3, the counting input of which is connected to the output bus 10, to the output of the second match 6, whose inputs connect with the direct output of the first and inverse outputs of the remaining bits of the subtracting counter 1, with the output of the third trigger 4 and with the bus 9 of the pulse train, which is connected to the input of element 7 NOT, the information inputs of the subtracting counter 1 are connected to the buses 11 of the code, and the output the third coincidence element 12 is connected to the output bus 14 of the first pulse and the C input of the fourth flip-flop 13, the inverse of which is connected to

80272 by the first input of the third match item 12.

The device works as follows.

 In the initial state, bus 8 does not have a control signal (zero level), bus 9 has an input continuous pulse

, Q sequence, which is inverted by element 7. At the outputs of the flip-flops 2 and 4 there are zero levels at the outputs of the elements 5, 6 and 12 and at the inverse outputs of the flip-flops

11, 3 and 13 - unit levels, on buses 11, for example, a binary code is set equal to (0101), which is also present on the outputs of counter 1; On bus 10 there is a single level of 2Q.

With the arrival of the control signal on bus 8 (by the difference from the zero level to the unit), trigger 2 is triggered and on its output there is bc with the unit level, which is set to triggers 4 and 13 (on the R input). At the same time, this level allows the zero level of the input pulse sequence with

3Q bus 9 pass through the element NOT 7 and the element 5 to the S input of the trigger 4, as a result of which a single level is established at its output, from which the lock is removed from the trigger 3, from the element 6, from the counter 1 and from the element 12. At the same time The first pulse from the input sequence of the bus 9 passes through the element 12, at the output of which a pulse is formed by it. A negative polarity pulse; at the end of this pulse, a difference is generated from the zero level to the unit one at which the trigger 13 is triggered, as a result of which in its inverse

at the output, a zero level is formed, blocking element 12. At the same time, a negative impulse is fed to the bus 14. In this case, counter 1 starts subtracting from the content equal to

gQ 0101. The subtraction is performed on a slice (difference on bus 9 from a single level to a zero) of each pass - MOGS1 impultsSa on the counting input to the cash account 1. Subtraction continues

gg until state 0001 remains in counter 1. During this time, counter 1 calculates four input pulses passed through bus 9. The next fifth pulse passes

35

through element 6 or 8 in the form of nuvog o uroin,

At the end of the fifth input pulse, the counter 1 is set to the zero state (LLC). At the end of the selected pulse, a difference occurs from the zero level to a single on bus 10, which triggered 3. As a result, a zero level appears on its inverse output, which (by R-BXO) triggers 2 the The zero level from the direct output of trigger 2 blocks elements 5 and 12 (unit levels appear at their output) and sets (on the R input) triggers 2 and 13 to the initial state.

The zero level from the output of trigger A blocks element 6 and confirms the blocking of element 12, while trigger 3 returns to its initial state; This level permits the entry of the entry of a code to permit the entry of code 0101 with the value 11 into the counter t and at the same time its input is blocked. The device returns to its original state.

When the next control signal arrives, the work cycle is repeated. Editor N. Kistutinets Order 4143/54
