PULSE GENERATOR Russian patent published in 2004 - IPC

FIELD: pulse engineering.

SUBSTANCE: pulse generator has NAND gate 1, NOR gate 2, EXCLUSIVE OR gates 3, 4, inverter 5 built around Schmitt flip-flop, resistors 6 through 9, capacitors 10 through 12, diodes 13, 14, and common bus 15. Generator stability in electrical noise environment is ensured by controlled switching unit which is immune to electrical noise and is built around EXCLUSIVE OR gate 2 and inverter 5. If short-time electrical noise changes state of gates 1, or 2, or 3, or 4, or inverter 5, or of a number of them at a rime, controlled switching unit will immediately recover state of faulty gate or component as this switching unit is immune to noise provided length of electrical noise does not exceed time constant of integrating circuit of resistor 9 and capacitor 12.

EFFECT: enhanced noise immunity in intensive electrical noise environment.
