FIELD: tool-making industry, possible use for determining bearing frequency within given range of frequencies and during generation of aimed noise interference at this frequency.
SUBSTANCE: to achieve effect in seizing mode singular video pulse is generated, adjustment of super-heterodyne receiver is halted for time, equal to duration of video pulse. Then voltage of intermediate frequency is formed and multiplied with voltage of heterodyne. Voltage of total frequency is selected, modulated by amplitude by noises, power-amplified and broadcasted.
EFFECT: expanded functional capabilities on basis of generation of aimed noise interference for radio-electronic suppression of radio-electronic equipment.
