The problem of increasing the noise immunity of data transmission from rotating components and mechanisms is considered. The aim of the work is to study the combined effect of three rectangular pulses of different polarity on inductively coupled circuits, causing their specific reaction, which forms the basis of the proposed method of transmitting and receiving data from the rotating part of information-measuring system to its stationary part. For this purpose, amplitude characteristics of individual half-waves of the reaction of inductively coupled circuits to three-pulse input action were obtained, which became the basis for develop ing a method for transmitting and receiving data through air gap. A circuit diagram of a device has been proposed that makes it possible to increase noise immunity of data transmission. A comparison of the degree of noise immunity of the proposed device with that of the known original device was made.
