| Abstract | This paper discussed improving EMI design based on propagation path impedance. The way conventionally used in EMI filter design barely includes information on propagation path impedances, although this information is well known as important to filter topology selection and its in-circuit attenuation; besides, filters attenuation is usually measured by small signal insertion gain, which is different from real in-circuit attenuation. This paper starts from the propagation path impedance characterization, and then it investigates into the impacts of the propagation path impedance on the in-circuit filter attenuation. Parasitic effects of the filter are included in the analysis. Parasitics creates multiply resonances and anti-resonances in the propagation path, which can be reflected in filter in-circuit attenuation. By accurate control and design of these parasitic, we can take the advantage of parasitics to improve the filter performance. Furthermore, knowing the relationship between filter impedances and propagation path gives better understanding of how to design an effective filter for noise reduction. |

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.
