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

摘要

A shaper of periodic sequence of packets of pulses with adjustable width, pulse number in a packet and fixed pause between the packets, equal to two cycles, contains two counters, first of which is a countdown counter having a clock input, a synchronous parallel load enable input and a loading data input, a counting mode enable input, an asynchronous reset, an overflow output, the second counter has a clock input, a counting mode enable input, an asynchronous reset, first and second elements OR, an inverter, a circuit element comprising in series connected resistor and capacitor, a start-stop device, a synchronous D flip-flop having asynchronous reset, first and second two-input elements AND. Third reversible binary countdown counter is introduced.
