Abstract
Electronic track circuit comprising a generator that provides between the two lanes of the path voltage pulses of short duration and small amplitude, characterized in that the receiver that collects the impulses at the end of the anticipated action area is made selective, by means of a resonant circuit, at the frequency of recurrence of the pulses emitted such that the scale circuit that drives the track relay exhibits a maximum sensitivity to the signals of this frequency.
