PULSE SEQUENCE SHAPER WITH ADJUSTABLE LENGTH OF PULSES WITH FIXED PULSE RATIO WHICH IS EQUAL TO THREE

摘要

A pulse sequence shaper with pulses of adjustable length and fixed pulse ratio equals to three comprises two countdown reversible binary counters, a countdown binary adder turned to fixed value equals to one, an inverter, first and second element OR; a circuit comprising in series connected resistor and capacitor, a start/stop device comprising a synchronous flip-flop having asynchronous reset input, enhanced structure of binary adder and second counter due to increasing of digit number per unit in comparison to digit number of first counter, a bus for turning device to required length of output pulses is connected to first group of adder inputs with one-digit shift to direction of upper-order digits and connection of carry input and input of low-order digit of first group of adder inputs to logical zero bus, all inputs of second group of adder are connected to logical unit bus.
