Evaluation of Noise Immunity of Channels with Rail and Inductive-Rail Lines

Modern train interval control systems contain communication channels between traffic organizers and the locomotive, using rail inductive as lines. The threads that make up these lines are an integral part of traction network and, therefore, current is channeled through them. Bearing this in mind, signals operate under conditions strong interference from current. At present, continuous automatic locomotive signalling continue to improve, so it necessary have information on relationship immunity their channels, particular interference, different signal parameters, such carrier frequency. This article deals with method evaluating influence frequency noise resistance comprising
