GENERATOR OF PERIODIC SEQUENCE OF DOUBLE-PULSE CODE GROUPS WITH PROGRAMMABLE TIME PARAMETERS

摘要

Generator of periodic sequence of double-pulse code groups with programmable time parameters contains: reversible binary counter that is configured to subtract mode, which has an input for supplying clock pulses, the input to the adjustment mode of addition/subtraction, the enable input of the counting mode, the enable input synchronous parallel load inputs and flow data, input asynchronously set to zero, an overflow output; synchronous D-flip-flop to the input of asynchronous setting to zero position; an inverter; first and second elements OR, the first and second elements, And; a chain. Introduced: the first and second JK-flip-flops with asynchronous inputs setup to zero; Three-input element of addition by module two; the first and second drivers with a Z-position output, the first of which has an inverted output enable input, and second – straight.
