| Abstract | State of the art analogue signal processing allows multi-channel systems to be commonly used to process multi-sensor systems. Nevertheless, specific situations arise where the values from only one input - especially vector physical quantities - are needed, but signal strength and/or efficiency of transducers is not enough to produce sufficient signal to noise ratio, bandwidth, or dynamic range and therefore one output might not be enough. This contribution carefully analyses the case of magnetic flux density vector field sensing where the input consists of 3 wide-bandwidth components (DC to up to 1 MHz) measured around the same space point. The instrument consists of 6 pairs of sensors arranged to obtain the field components estimations around the same sampled point in space. millitesla range measurements were achieved with a noise spectrum of 20 - 50 pT/√Hz up to 1 MHz. These observations are discussed to evaluate the relevance of the concept to other physical quantities. |

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.
