| Abstract | In this paper three different digital filter structures for decimation by a factor of 64 are compared. They are based on a commercially available decimator AD7722 by Analog Devices. The AD 7722 is a complete low power /spl Sigma//spl Delta/ analog-to-digital converter with the application in digital audio processing. The applied filter is a two-stage decimator which decreases the sample rate by 32 and 2 respectively. This structure is then compared to a state-of-the-art approach of a FIR decimator with six stages, each of them performing decimation by a factor of 2, and to two different approaches to an almost linear phase IIR decimator based on an very efficient class of lattice wave digital filters with also six down-samplers. The advantages and disadvantages of the selected structures are described. |

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.
