The invention relates to the field of automation and computer technology and can be used to convert data without changing the amount of information as a converter of a parallel code into a pulse code or pulse duration.

The purpose of the invention is to increase the reliability of the converter.

The drawing shows the functional diagram of the Converter

The converter contains 1 generator of pulses, triggers 2,3, element 4 and counter 5, the first (informational) and second (control) inputs 6.7 of the converter, the bus 8 of the unit potential and the first to third outputs 9-11 of the converter

Converter code into a burst of pulses (pulse duration) works as follows.

In the initial state, the triggers 2 3 go to zero state (cleared), counter 5 records the code of the number applied to input 6, element 4 is closed and the generator 1 pulses do not pass through it. output 10 has a single signal (signal of a single level), output 11 has a zero signal (CHS level zero) Setting the converter to the initial state after turning on the power is performed by applying a zero level pulse directly to the reset input of the trigger 3 and through the OR element to the reset input tr The igger 2 circuit of the converter is reset to the initial state in the drawing, but is shown

When a single signal arrives at input 7 on the front signal front (forward 0-1), trigger 2 is set to a single position. A single signal from a single output of trggea 2 opens element 4 and is fed to the corresponding input of trigger 3 On the leading edge of the first trigger 2 after installation of the generator pulse i, the trigger 3 is set to one, an output pulse begins to form at output 11, and element 4A fully opens and the generator 1 pulse, which sets the trigger o, goes to the single position at output 9 and to the third (subtractive) input counter, 5 from which content is subtracted t

Subsequent pulses of the generator 1 are passed to output 9 and to the third input of the counter. 5, subtracting each of its contents by 1 At the moment of the end of the pulse recorded in the counter 5, the zero code (the number of this pulse is equal to the number whose code is on the inputs 6) appears to be a zero signal at the output (credit) of the counter 5 arriving at the output 10 Besides trigger 2

is set to zero position, while element 4 closes. The next pulse of generator 1 sets trigger to zero position 3 and output output pulse ends at output 11. By zero signal from trigger output 3, the sieter 5 records the code from input 6 a pack of pulses returns to its original state at output 9

a packet of pulses from N pulses to output 10 is a zero pulse delayed by time (NT - in), where N is the number of pulses, T is the pulse period, tn is the duration of the pause between pulses, with respect to

the time of the first impulse output 9, an output pulse duration NT was given at output 11

The invention of a code converter into a burst of pulses contains an element, And the output of which is the first output of the first three (g) output of which is the first input of the AND element and the counter, the second inputs of which are

the first ROKDZMI transformed output — output by the output of the second input of the element AND and the first input of the nepsoi e trigger are combined and a pulse generator characterized in that

To increase the reliability of the converter, the second trigger and the tire of the simple unit of the pulse generator are connected to the third input of the element I and the second input of the first trigger output

which is the converter's first trick, the second inputs of the second trigger are connected to the output of the counter and the bus of the logical unit, respectively, the second input of the AND element and the first input of the first

the trigger is connected to the output of the second trigger, the third input of which is the second input of the transceiver. The output of the AND element is connected to the third input of the CL Tchio.
