摘要
FIELD: radio engineering, communication.;SUBSTANCE: apparatus comprises series-connected first frequency converter, first convolver, filter, envelope detector and duration selector. The apparatus also includes a second frequency converter and a second convolver, two delay lines, two adders, a limiting amplifier, a pulse generator and a logic circuit. The pulse generator, second convolver, limiting amplifier, second frequency converter, first delay line and first adder are connected in series; the output o the first adder is connected to the additional input of the first convolver, the output of the second adder is connected to the input of the first frequency converter, the input of the second adder is connected through the second delay line to the additional inputs of the first and second adders and the additional input of the second convolver; inputs of the logic circuit are connected to inputs of the duration selector.;EFFECT: broader functional capabilities.;2 dwg
