Abstract (en)

[origin: EP1746008A2] The arrangement has a controller (4) charging a frequency generator (5), whose output signal is coupled to a track circuit (1) by an output stage. The generator generates two control signals, where one of the signals is offset to the other signal around 90 degrees. The control signals are guided to control inputs of respective synchronous rectifiers (7, 7.1), where one rectifier is connected to the controller by a low-pass filter. Signal inputs of the rectifiers are connected with the signal generated by the track circuit.
