Abstract: Shaper periodic sequence of three pulse code series of programmable duration of the pause between pulses in the series, which includes: two reversible binary counters, each of which has an input supply pulse synchronization input adjustment on mode summation / subtraction, entry permit simultaneous parallel downloads and inputs supply data entrance permit counting mode, asynchronous input settings in the zero state, the output overflow; the first and second elements OR; inverter; chain consisting of series connected resistor and capacitor; synchronous D-flip-flop with asynchronous input settings in the zero state, the first and second elements two-charge and while the common point of series connected resistor and capacitor connected to the information input of D-trigger inputs from the first and second elements two-charge I; the second input of the first element and creates supply input pulse stops (Stop) forming the output pulse; D-trigger output connected to the input of the first OR element, whose output is connected to a second input of the second element I; two-charge output of the first element is connected to the input of asynchronous installation D-flip-flop in the zero state; the output of the second OR element connected to the input of a permit simultaneous parallel loading the first counter; the output of the first counter overflows, which forms the generator output connected to the input of the first element OR and inverter input, the output of which is connected to the input mode permits counting of the first counter; second counter overflow output connected to the input of the first OR element; value signals at the inputs parallel data download counter first determine the duration of the output pulse shaper; parallel loading inputs of the second counter inputs form shaper programming on the same pause between pulses; the output of the second element is connected to the input of asynchronous installation of meters in zero condition; clock inputs of the first and second counters are interconnected, creating shaper input - input supply continuous periodic sequence of pulses output from the external oscillator; clock input of D-trigger input supply creates impulses run (Start), and enter: two-charge summed up counter that has an input supply synchronization pulses, entry permit counting mode, asynchronous input settings in the zero state; the third element OR; a second inverter; NAND element, one input is connected to the output of the second overflow counter and the second input element OR; second input NAND element connected to the output of the first inverter; output of NAND element is connected to the input mode permits counting of the second counter; a second input of the second OR element connected to the output of the second inverter, whose input is connected to the input of the first element and the release of the third OR element OR, the first input is connected to the output of the first level of the third counter and entering third level data parallel loading the first counter ; the second input of the third OR element connected to the output level of the second and third counter input of the first category of data loading the first counter; asynchronous input settings in the zero state summed up counter connected to the output of the second element I; summed up counter clock input connected to the input shaper.
