Description

The invention relates to a pulse technique and can be used in automation devices, in measuring devices.

A device is known for dviguing the first pulse of a series containing a trigger, an OR element, two AND elements and an inverter 1.

A disadvantage of this device is the complexity and impossibility of subtracting the first pulse from the series.

The closest to the invention according to the Technical essence is a device for separating the first pulse from a series, which contains a trigger, the S input of which is connected to the control signal bus, and a pulse series bus, in addition, there is an And element, the first input of which is connected to the pulse train and the S-Input of the trigger, G and K-inputs of which are connected to the output of the trigger and the second input of the element And 2.

A disadvantage of the known device is the complexity (used with 3, K-trigger and element I) and limited functionality (does not provide the subtraction of the first pulse from the series).

The purpose of the invention is to manipulate the device and expand the functionality, namely: both stopping the subtraction of the first pulse from the series.

The goal is achieved by the fact that a switch, S-input of which is connected to the control signal bus, and a series of impulses, has a switch 6 with a control signal, the control input of which is connected to the trigger output / RB whose stroke is connected to the first output bus and the first output of the switch with the storage of the control signal, the second output of which is connected to the second output bus, and the switching input is connected to the pulse train bus.

Figure 1 shows the block diagram of the device; in figure 2. timing charts explaining his work.

The device comprises a signal-control bus 1, a bus 2 of a series of pulses, a bus 3 on which you are. the first impulse from the series is made, the bus 4, on which the impulses from the series are selected, except for the first, 0 trigger, 5. R.-S-type and switch 6 with memory of the control signal,

The device works as follows.

In the initial state, when HHi 5 TIRES 1 and 2 pulses are not given, trigger 5 is in state 0, signals 1 are present at the outputs of busbars 3 and 4 (high levels of equalization}.

Filed on bus 1 pulse 7

Control 0 sets the trigger 5 to the state, and a signal is sent to the control input of the switch b.

On the bus 2 device is fed

5 series of pulses 8. The first pulse 12 of this series is switched by the switch 6 onto the bus 3 of the device (.impulse 10) and switches the trigger 5 to the state O. The second pulse

Series 0 - pulse 13, as well as all subsequent pulses of the series are connected by switch 6 to bus 4 (pulses 11). Thus, the device produces

5 of the first impulse from the series, and

the first pulse of the series is allocated on the bus 3 of the device, and also subtracts the first pulse from the series of pulses, with the series of pulses

A liter without a first pulse is formed on the bus 4 of the device.

The device does not change the duration of the pulses in the series, as can be seen from the timing diagram - pulses 13 and 14, pulses 15 and 16, they

5 pulses 12 and 10.

The proposed device is simpler known and allows an additional series of pulses to be implanted without the first pulse of the series.
