Abstract

Periodic pulse generator with programmable number of pulses per series, as well as pulse duration and pauses between pulses and between series, containing: two reversible binary counters tuned to subtraction mode, each with input pulse input to synchronization mode, input to synchronization mode input summation / subtraction, synchronous parallel load resolution input and data inputs, counting mode input, zero asynchronous input, overflow output; the first and second elements OR; inverter; a circuit consisting of a series resistor and a capacitor; synchronous D-flip-flop with zero input asynchronous input, first and second two-input elements And; the clock inputs of the first and second counters are interconnected, creating an input of the shaper - the input of a continuous periodic pulse sequence from the output of an external generator; the clock input of the D-flip-flop creates an input of pulse start (Start). Additionally introduced: third and fourth reversible binary counters tuned to subtraction mode, each of which has a pulse input pulse input, summation / subtraction tuning input, synchronous parallel boot resolution input and data input, input mode input input, to zero, overflow output; third and fourth inverters; the first, second and third elements I-NO; the third element OR; the third element And; the overflow output of the first counter is connected to the first input of the second element OR, the output of which is connected to the input resolution of the digit mode of the second counter.
