NOISE PULSE GENERATOR Russian patent published in 2022 - IPC H03B29/00 

FIELD: radio engineering and electronics.

SUBSTANCE: invention relates to the field of radio engineering and electronics and can be used to protect computer equipment from leakage of processed information as a result of spurious electromagnetic radiation. The noise pulse generator additionally contains an additional path for generating nanosecond random pulses, connected to the main generator and equipped with an additional power supply system, consisting of a unit for generating nanosecond pulses from the output noise pulses of the main noise generator and implemented on the principle of time delay of the output pulses from the modulo 2 adder of the main generator followed by logical AND multiplication of delayed and undelayed signals and a block of amplifying key stages of noise pulses of nanosecond duration. A standby multivibrator in the restart mode is connected to the output of the block of amplifying key stages of noise pulses of nanosecond duration. The additional path is made with the presence of galvanic isolation from the main generator.

EFFECT: expanding the spectrum of the output noise signal through the use of an additional path for the formation of random pulses of nanosecond duration.
