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 - 8, capacitors 9 - 11, diodes 12, 13, and common bus 14. Immunity of controlled switch built around EXCLUSIVE OR gate 2 and inverter 3 to electric noise ensures immunity of pulse generator to external electric noise. If short-length electric noise pulse changes state of gate 1 or 2, and that of inverter 3 or inverter 4, or of some of them at a time, controlled switch will immediately recover state of faulty component as this controllable switch is immune to noise provided electric noise length does not exceed time constant of integrating circuit of resistor 8 and capacitor 11 inserted in feedback circuit of controllable switch.

EFFECT: enhanced noise immunity at intensive electric noise.
