| Abstract | Cable ferrites are widely used on wires attached to electronic devices and components to fulfill the requirements of the EMC regulations. Until today many manufacturers of those passive components refer to a simple measurement procedure in order to obtain a ferrite-impedance-versus-frequency-chart for their datasheets. This setup renders only a special case for the cable termination which is far away from a realistic application. From the datasheet graph one could conclude that a particular ferrite is less useful above its peak impedance. We want to correct this misinterpretation, as our investigation clearly shows that the attenuation can reach up to several gigahertz. In the following paper we describe a new approach for the characterization of cable ferrites, using a TEM-waveguide. This leads to an equivalent circuit with a new set of more representative ferrite parameters. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
