Description

one

The invention relates to radio electronics and can be used in electronic computing devices, and in setting automation software devices.

Devices are known for forming a series (bursts) of pulses, containing a generator of a continuous sequence of pulses, a key device, triggers, (or an adder) of pulses, a software device (or a set of switches) for setting the parameters of a series (packs) of pulses, a group of gates and logic circuits one.

These devices allow a series of shapers (bundles) of pulses with different predetermined parameters, but are characterized by either relatively high complexity or relatively low reliability (stability) of operation.

The closest in technical essence to the invention is a device for forming a series of pulses, comprising a pulse generator, a key device, counting / reading of pulses, circuits AND, a program storage unit and a trigger, with the output of the VeHepaTopa pulses

The device is connected to the input of the counter impulses and outputs 6. 6. 6 storage of programs is then connected through the circuits and to the corresponding inputs of the pulse counter, the output of which is connected to the input of the storage unit of the program section 1 to the one of the trigger outlets, the second input of which is connected to the inputs of the And and the output of the block

0 program storage as well. the trigger output is connected to the control input of the key device 2.

However, this device has relatively low reliability.

The purpose of the invention is to increase reliability.

The goal is achieved by the fact that in the device for forming

0 bursts of pulses containing software, a block whose outputs are connected to the counter inputs. pulse, continuous pulse train, the output of which is connected

5 with a key input, the second input of which is connected to the ftMxolayCTatTi Jeckoro trigger, and the output is connected to input 5I of the pulse counter, the overflow output of which is connected to the first

0 To the INPUT of the program block, the first impulse-potential is connected in series. valve and element OR, / as well as series-connected element NOT and a second impulse-potential valve, the output of which is connected to the input of a static trigger, and the second input is connected to the output of the generator of a continuous pulse train .and the first input of the first pulse-potential valve, the second input of which is connected to the output of the NEBEM and to the control board of the program block, with the output of the first Impulse – Potential Valve having a single input with the second input of the software. block, the TiepetTOJTHeHHrt output of the pulse counter is connected to the second input of the OR element, the output of which is connected to the second input of a static trigger. . The structural electrical circuit of the device is shown in the drawing. The device contains a generator of a Continuous sequence of pulses 1, a key 2, a static trigger 3, a pulse counter 4, a software spin 5, a pulse-potential. valves 6 and 7, the element OR 8, the element NOT 9, the output of setting the counter to the initial state 10 and the control output of the software block 11. The device works as follows. After switching on the device, the generator 1 starts producing a continuous sequence of unipolar pulses with a period T, which is fed to the input of the key device 2 and to the inputs of valves b and 7. In the initial state, when the program block 5 is not turned on (or not turned on full size), its control output 11 will be zero (or / close to zero) the potential by which the zentil b would be held in the open state, and the valve 7 through the element 9 -. in a closed state:) I) NII Pulses from the output of the generator 1, running through valve b and the element OR 8, set (first power after switching on) and underneath live trigger 3 at zero deadline. . At the output; trigger 3 will have a low v potential, as a result of which key device 2 will be closed, and the pulses from the output of generator 1 to the ALARM key 2, which is. at the same time, the whole device will not come out. The pulses coming from the output switch to the input of program block 5 will not change the state of the latter, since it is not turned on. This state of the device can last for how long until the time t corresponding to the moment the software block 5 is turned on. At the time t, the anti-virus block 5 is turned on (the time tp can coincide with the moment when this device is turned on). The first pulse, output from the output of the valve 6, passes into the program block 5 to the bus 0 zero inputs of the impulse counter bits, 4 and installs the meter to its initial state. This e pulse triggers the first frame of the program embedded in program 5, which commits one output corresponding to the number. N 2- M, de P - the number of bits of the pulse counter, M - the number of pulses in the first burst, sets the start time t forming the first block of pulses (for example, the inputs of the counter in the 4lnm block are switched to record the number A C, which sets the delay in the onset of the formation of the first pack t relative to tf ,, nii6o, for example, it sets the delay time using the delay line). The second impulse arriving at the entrance of the program block 5 is recorded with the number N in the count of pulses at the switched code outputs; 4 (as well as; for example, writes the number A to the schftchik of the program block). For reliability, the record of the number N in the counter 4 can be repeated as many times, how many pulses are received, the dO is the time t. After the input of the program block 5, for example, C pulses, start with the third control output 11 of the program block at the moment in time t. Vits low potential, which closes the valve 6, and through the element NOT 9 opens,. valve 7.. - The first time from the time t, the pulse from the output of the pulse generator, 1. goes through the open valve 7 to the single input of the trigger 3, the trigger is set to one and opens the key 2, Therefore the first pulse to the device’s output does not pass and the possibility of falling into a packet of defective impulse is excluded. -..- The next impulse from the output of the gene-. The rator 1 passes through the public key 2 to the output of the device, and from this moment t the first packet begins. pulses. The same pulse is fed to the counting input of the pulse counter. During the whole time of the duration of the burst, the trigger 3 is maintained. pulses from the output of the valve unit 7 in the state.
