| Abstract | Based on the Fourier Slice Theorem, through analyzing the physical significances of the DFT and the relationship between the DFT and the FFT, this paper proposed a new way for implementing the Tau-P transform by the FFT. By comparison with other existing ways, the mainly difference of the forward process is to directly convert signal from f-x domain to f-p domain other than from f-x domain to f-k domain and then through interpolation and coordinate transform to f-p domain, and the inverse process is converse. Otherwise, two points need to be considered, the first is that the number for the FFT on the process from f-x domain to f-p domain is variable with the frequency sample. The bigger the frequency is, the smaller the number for the FFT. The second is that the background energy should be recalled for faithfully reconstructing the copy of the original data. Through the example testing, the new Tau-P transform proposed here is the reversible process. Meanwhile, the new way is faster since its three steps all implemented by FFT, no interpolation and coordinate conversion like other ways. |

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.
