SHAPER OF PERIODIC SEQUENCE OF PACKETS OF PULSES WITH FIXED WIDTH EQUAL TO THREE CYCLES AND ADJUSTABLE NUMBER OF PULSES IN PACKET AND PAUSE BETWEEN PACKETS

摘要

A shaper of periodic sequence of packets of pulses with fixed width equal to three cycles, with adjustable number of pulses in a packet and a pause between the packets comprises three counters, four OR elements, two AND elements, two AND-NOT elements, two inverters, a circuit comprising in series connected a resistor and a capacitor, a start-stop device comprising a synchronous d-type flip-flop having asynchronous reset.
