FIELD: physics.
SUBSTANCE: device comprises a filter connected to the terminals installed on the locomotive of the signal receiving coils ALS, a two-sided amplitude limiter, a series-connected amplitude detector, an integrator, and a threshold limit setting unit connected to the input of the control limiter by its output, the input of which is connected to the output of the filter, and an output - to the input of the locomotive receiver ALS. Moreover, the output of the filter is connected to the input of the amplitude detector, the integrator is configured to set the integration time constant, and the filter is designed as a low-frequency filter or a notch filter tuned to the frequency of 50 Hz.
EFFECT: increasing the efficiency of suppressing the impulse noise in the input of the locomotive receiver ALS.
