Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A DMS filter comprising: first and second transducers of a first type, each coupled in series between a common node and a reference potential; a transducer of a second type, the first and second transducers of the first type and the transducer of the second type being arranged in a DMS track and being selected from input transducers and output transducers; and a first concentrated element, wherein the first transducer of the first type is coupled t…
