Abstract (en)
[origin: EP1746009A2] The arrangement has a controller (4) controlling a frequency generator (5), whose output signal is output in a track circuit (1) by a power amplifier (6). The generator generates a control signal that is directed to a control signal of a synchronous rectifier (8) by an exclusive-or gate (7). The controller has an evaluation or comparison unit for evaluation or comparison of sum values of inverted and non-inverted correlation signals. A signal output of the synchronous rectifier is combined with a signal that is output from the track circuit.
