FILTER OF RECTANGULAR VIDEO PULSE Russian patent published in 2008 - IPC G01S13/28 

FIELD: physics; radio.

SUBSTANCE: invention is related to radio engineering and may be used in facilities for radio location, radio navigation and radio communication for processing of signals. Limiter at the bottom at zero level and limiter at the top at zero level are introduced, while both are connected with their inlets to outlets of the first subtracting device, the second delay unit, which is connected with its inlet to outlet of limiter at the bottom at zero level, adder for two inlets, which is connected with one inlet to the outlet of the second delay unit, and with the other inlet - to outlet of limiter at the top at zero level, the second subtracting device, connected by minuend inlet to outlet of the second delay unit, and by subtrahend inlet with outlet of limiter at the top at zero level, the first and second calculators of module that are connected by inlets with outlets of adder and the second subtracting device accordingly, the third subtracting device that is connected by minuend and subtrahend inlets to outlets of the first and second calculators of module accordingly, and by outlet to integrator inlet. Value of delay in the first unit is less, and in the second delay unit it is equal to duration of processed video impulse.

EFFECT: higher noise immunity of filter under conditions of pulse noises and noises of outburst type.
