Abstract | this article implements a design of digital programmable filter. It is consisted by the programmable filter module, the amplifier module, the system control module and the human-machine interface module. Among them, the digital programmable filter module is based on programmable filter chip MAX262; the amplifier module is constituted by the AD524 and the D / A converter AD7528; and the system control modules used a single-chip microcomputer and FPGA. The amplifier gain can reach 60dB, and it can be adjusted by the step of 10dB, the gain is almost independent of frequency. The gain of high-pass filter and low-pass filter in the cutoff frequency achieved -3dB. |

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.
