| Abstract | This paper proposed a solution for arbitrary waveform generator (AWG), in which integrated DDS chip is engaged as the essential frequency variable clock source. DACs are driven to generate the waveforms by clock signals, which are obtained from the reshaping and shape lifting of output from DDS by clock distributor. The data to build waveform up are stored in cache and loaded into DACs continuously by FPGA. An embedded process was set up in FPGA and would interpolate data from envelope when output of whole system is required to be typical reference. AGC circuits then standardize signal out of DACs to a constant peak-to-peak value, and VGA is obliged to fit the amplitude of signal as same as settings. Finally, the signal flow out this generator via BNC over filtering. In author's practice, a demo with performance of 200Msps rate and 100MHz above analog bandwidth can be achieved. |

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.
