Abstract
A DMS filter has improved signal suppression in fly-back. At least two transformers of a first type are connected in parallel between a common node of the signal path and a ground connection/reference potential. A concentrated element is connected in the signal path of said transformers of the first type, so that the voltages present at the first transformers are different from each other.
