| Abstract | The paper proposed a novel method for implementing Zoom FFT with field programmable gate array (FPGA) for high performance spectral analysis. A scheme of multistage decimation Zoom FFT was given by using the parallel pipelining processing character of FPGA to reduce the computational complexity of traditional Zoom FFT. Meanwhile, a polyphase filter suitable for high decimation-times was designed, and then the polyphase filter and an efficient cascaded integrator-comb (CIC) filter were applied into every stage of decimation structure. Simulation result indicates that compared with single-stage decimation structure, our method's error of amplitude analysis can be lower than 1dB for 200 of decimation-times, so that maximum Zoom-times and precision can be improved. The method can reduce FPGA resources consuming and achieve high processing speed. |

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.
