DEVICE FOR CONVERTING PERIODIC SIGNAL PHASE DEVIATION Russian patent published in 2004 - IPC

FIELD: radio engineering; phase deviation conversion using any desired conversion factor.

SUBSTANCE: device has first mixer 1 whose first input is connected to output of first bandpass amplifier 2; second mixer 7 whose input is connected to output of second bandpass amplifier 6 and output, to input of first bandpass amplifier 2; third mixer 4 whose inputs are connected to outputs of first and second bandpass amplifiers 2 and 6, respectively; recorder 8 whose first input is connected to output of third bandpass amplifier 5 and output of first mixer 1 is connected to initial phase converter 3 whose output is connected to input of second bandpass amplifier 6; connected to second input of first mixer 1 is input of device and to second inputs of second mixer 7 and recorder 8, reference signal input. Initial phase converter 3 has fourth adder 9 whose both inputs and input of multistage bandpass amplifier 12 are connected to output of fourth bandpass amplifier 11 whose input functions as input of initial phase converter 3; fifth adder 10 whose first input is connected to output of fourth adder 9, second input, to output of bandpass amplifier 12, and output functions as output of initial phase converter.

EFFECT: provision for converting periodic signal phase deviation using arbitrary conversion factor higher than unity in technically realizable band.
