| Abstract | The emerging availability of precision time synchronization, such as that provided by IEEE 1588 Precision Time Protocol, make it desirable to have signal processing methods available for signals that are sampled at non-uniform intervals but have the sample times accurately recorded, or time-stamped. Rank order filters, including median filters, are well known in discrete time signal processing. Such filters are used for such purposes as signal de-noising without ringing and robust esimation of signal mimimum and maximum values. The question considered in this paper, then, is: Are there efficient analogues in the domain of time stamped signals for rank order filters ? The answer is yes. This paper shows how to transfer a theory from the literature concerning rank order filters for analog signals to the domain of time-stamped signals, discusses how to implement the resulting rank order filters efficiently, and shows the results on actual time-stamped, measured data. |

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.
