PULSE GENERATOR Russian patent published in 2004 - IPC

FIELD: pulse engineering.

SUBSTANCE: proposed pulse generator has EXCLUSIVE OR gates 1,2, inverter 3 built around Schmitt flip-flop, and inverter 4, resistors 5 - 9, capacitors 10, 11, diodes 12, 13, and common bus 14. Immunity of state controllable switch built around EXCLUSIVE OR gate 2 and inverters 3, 4 to electric noise of pulse generator ensures immunity of pulse generator to external electric noise. If short-length electric noise pulse changes state of gate 1 or 2, inverter 3 or 4, or some of them at a time, state controllable switch will immediately recover state of faulty component or components as state controllable switch is immune to noise provided electric noise length does not exceed time constant of integrating circuit of resistor 9 and capacitor 11, phase and time of swing being maintained constant.

EFFECT: enhanced noise immunity in high-intensity electric noise environment.
