ELECTRONIC CIRCUIT ARRANGEMENT AND METHOD

An electronic circuit arrangement for an electric charging station and a method for configuring a an electrical frequency filter device of an electronic circuit arrangement are disclosed. The electronic circuit arrangement includes an electrical pilot contact and an electrical earth contact, to which an electric motor vehicle for forming an electrical communication connection are electrically connectable. An electrical oscillator, for generating a pulse width modulated electrical communication signal, is arranged in an electrical line path and subdivides the line path into a pilot portion ending in the pilot contact and an earth portion ending in an earth contact. A frequency filter device is arranged in the pilot portion of the line path.
