FOUR-CHANNEL DISTRIBUTION DEVICE OF PERIODIC SEQUENCE OF PULSE PACKAGES WITH ADJUSTABLE PERIOD, PULSE LENGTH AND PULSE QUANTITY IN A PACKET

摘要

A four-channel distribution device of periodic sequence of pulse package with adjustable period, length and pulse quantity comprises two reversible binary counter-down counters in a packet, each of which comprising clock input, synchronous parallel load and load data input; counter mode enable input, asynchronous reset input, overflow input, inverter, first and second OR elements, a circuit comprising in series connected resistor and capacitor, start-stop device comprising synchronous D flip-flop having asynchronous reset input, first and second AND elements. Second inverter, two JK flip-flops having by two J and K inputs, asynchronous reset input, third, fourth, fifth and sixth AND elements, outputs of which form outputs of distribution device, a modulo two element are incorporated.
