FIELD: physics.
SUBSTANCE: invention relates to telemetry, in particular, to transmission and reception of pulse signals through an air gap, and can be used in systems for transmitting and receiving data from working members of rotating assemblies and mechanisms. On rotary part of device pulses of bits of information code are used to excite primary circuit of inductively coupled circuits, secondary circuit of which is separated from it by an air gap and is located on fixed part of device, characterized by that short of excitation pulses are formed from bits of code, as compared to their duration, positive and negative half-waves of reaction to them in fixed part of device are integrated by first and second integrators, which zero at the end of each digit of data code, obtained integrals are compared on two comparators with identical in absolute value, but different sign by threshold, value of which is selected proceeding from the shape of short pulses and operating mode of connected loops, signals from outputs of comparators are supplied to inputs of the AND element, at the output of which recovered values of bits of the data code transmitted through the air gap are obtained.
EFFECT: technical result consists in improvement of noise immunity of transmitted data.
