Arrangement for processing a non-symmetrical and a symmetrical signal

An arrangement for processing a signal balanced to ground, the arrangement comprising:

• an apparatus operable to unbalance and filter an image frequency of a nominal frequency of the signal balanced to ground, the unbalancing representing a conversion of a signal balanced to ground into a signal not balanced to ground with a nominal frequency, the apparatus comprising:
• a modified Boucherot bridge having a series or parallel oscillating circuit instead of inductive or capacitive components found in a conventional Boucherot bridge, such that the modified Boucherot bridge is in a harmonized state for the image frequency to be faded out and has a predetermined impedance with the nominal frequency on a non-symmetrical output terminal of the modified Boucherot bridge,
• wherein the arrangement is operable to transmit the nominal frequency as a non-symmetrical signal to the non-symmetrical output terminal of the modified Boucherot bridge.
