UA116381U - PERIODIC SEQUENCE FORMER WITH FIXED COLLECTION, WHICH IS EQUAL TO THREE, WITH PROGRAMMED PULSE DURATION AND START START DELAY - Google Patents

Abstract

The shaper of the periodic sequence with a fixed duty cycle equal to three, with a programmable pulse duration and a delay in the beginning of the formation contains a synchronous D-flip-flop with the input of the asynchronous setting to zero; a reversible binary counter configured for subtraction mode, having a synchronization pulse input, a count mode input input, an asynchronous setpoint input to zero, an overflow output, a synchronous parallel loading mode resolution input, and a loading input; inverter; the first and second elements OR; the first and second two-input elements I; a circuit consisting of a resistor and a capacitor connected in series. while the clock input of the meter forms the input of the shaper - the input of the periodic sequence of pulses from the output of the external generator; the clock input of the D-flip-flop forms the input of the start pulses; inputs of parallel loading of the counter, form inputs of adjustment of the shaper on the set duration of output pulses. The third element I is introduced; element OR-NO; the first and second JK-flip-flops with inputs of the asynchronous installation in the zero state, which form a cyclic device (second counter) with a sequence of transitions 00-11-10-00 (0-3-2-0); the first JK trigger has one input Κ and two inputs J connected by I, the second trigger has one input J and two inputs Κ connected by I.
