| Abstract | In this paper, we propose a new EEG autoanalysis system based on the Fujimori method in order to resolve the problems experienced when applying the Fujimori method to the EEG autoanalysis system. The Fujimori method involves the simulation of diagnosis, where EEG analysis specialists perform diagnosis using their eyes. However, the Fujimori method is not developed for use on a computer. Thus, there have been several reports on EEG autoanalysis using the Fujimori method. We have also developed a system based on the Fujimori method, but this system has several problems. First, the deterioration of frequency resolution at high frequencies. Second, the analysis is over a finite time, even though the system was developed for a clinical EEG test. Finally, underutilization of the advantage of the Fujimori method, which can be used for analysis in the time domain. Thus, the new system resolved the problems discussed in the present paper. First, by oversampling with the 4th band filter, the system improved the frequency resolution. Next, using ring buffers and binary files, the system can be used for real-time and infinite-time analysis. Finally, by creating a frequency graph next to the graph of the EEG and analysis results, we can determine the frequency of each wave at exactly the time at which the wave occurs. |

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.
