FIELD: radio engineering. SUBSTANCE: device measuring time position of angle-measuring signal includes synchronizer and matched filter, amplifier detector and signal maximum hold circuit connected in series, second input of the latter is linked to output of synchronizer. Signal maximum hold circuit incorporates pear detector and delay element, amplifier, controlled limiter and time position hold circuit connected in series. Time position hold circuit has first differentiating network, amplifier-limeter, second differentiating network and limiter connected in series. In this case first and second inputs and first and second outputs of signal maximum hold circuit are correspondingly interconnected inputs of delay element and first input of peak detector, second input of peak detector, output of time position hold circuit and interconnected output of peak detector and second input of controlled limiter. For increase of precision of measurement of time position of angle-measuring signal under changing noise condition device is inserted with N nonlinear converters, N additional signal maximum hold circuits, unit of selection of maximum signal, squarer, subtracter, first second and third comparators and commutator. Output of amplifier detector is connected to input of each of N nonlinear converters. Output of each of them is connected through like N additional signal maximum hold circuits to like pair of inputs of unit of section of maximum signal. Second output of maximum signal hold circuit is connected to first input of commutator through first comparator and to second input of commutator through squarer, subtracter and second comparator connected in series. First output of unit of selection of maximum signal is connected to third input of commutator through third comparator and second input of subtracter, first output of signal maximum hold circuit is connected to fourth input of commutator which fifth input is linked to second output of unit of selection of maximum signal. Second input of each of N additional maximum signal hold circuits is connected to output of synchronizer. EFFECT: increased precision of measurement of time position of angle-measuring signal. 1.
