FIELD: telemetry data transmission.
SUBSTANCE: method for transmitting and receiving data is characterized by the fact that it involves excitation of a rotating circuit of inductively coupled moving and stationary circuits with a short rectangular pulse, causing a bipolar signal on the stationary circuit, the half-wave shape features of which make it possible to reliably restore code messages based on the threshold conversion of half-waves into a digital signal with their logical processing. Excitation pulses cause a signal on the secondary circuit that is close to bipolar, which is processed by two comparators with opposite-polar thresholds equal in absolute value. Using the exclusive OR element, discrepancies between signals at the outputs of the comparators are detected and, based on their presence, the fact of transmitting a single signal is registered on the trigger.
EFFECT: increasing the noise immunity of transmitted data.
