| Abstract | The method of stabilizing termination impedance at AC cables is discussed to improve the reproducibility of test results between test sites. The common-mode absorbing device (CMAD) and the VHF band line impedance stabilization network (VHF-LISN) were investigated as the devices which can stabilize the termination impedance, and the investigation indicated that the deviation between test sites depended on the type of equipment when CMAD was used as the device. The phenomenon was studied by connecting the artificial network (AN) to the AC cable end. Comb generator and PC were used for the study as EUT. The termination impedance of the AC cable was changed by the AN, and then, the radiated electric field strength and the common-mode current were measured. The investigation indicated that the standard deviation of the field strength is similar to that of the common-mode current. The AC cable with CMAD and the AN were presented by an equivalent circuit, and the circuit parameters were determined from the measurement value of S-parameters. The equivalent circuit and disturbance sources of EUT were determined from the measured currents intensity and S-parameters. The common-mode current was calculated when the termination impedance of the AC cable was changed, and the standard deviation of the common-mode current was estimated. The comparison with the measurement value showed that the type of EUT influenced the deviation between test sites. |

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.
