| Abstract | In a single-semester course that incorporates both lecture and design, time constraints make it difficult to provide students with a substantive design experience that addresses multiple system elements. This paper presents a design experience that addressed numerous facets of a biomedical signal acquisition system by merging design credits for two undergraduate, senior-level courses: EECE 773 - Bioinstrumentation Design Laboratory and EECE 628 - Electronic Instrumentation. The innovative effort joined the sensor circuitry and signal display elements of a bioinstrumentation course with the data acquisition and serial communication topics often taught in electronic instrumentation courses. The overall goals of this project were to (a) create a substantial, design-driven learning experience for electrical engineering seniors and (b) increase student interest by attaching a biomedical context to an instrumentation project that would otherwise be generic. These goals were supported by 11 learning objectives that address clinical context, project planning, project roles, signal conditioning, signal management, printed circuit board development, biomedical data display, and written communication. In the initial project offering, 18 students were divided into three teams, each of which designed and built a system to acquire, process, and display data from multiple biomedical sensors, where the signal conditioning functionality for each sensor was remotely programmable. Each acquisition board communicated with a custom Lab VIEW interface via a Universal Serial Bus link. Development foci for each team changed over time as technical choices led to unexpected design complexities. Assessment of the experience was provided via a post- project survey that addressed the 11 learning objectives, learning in 16 technical areas, interpersonal team dynamics, and project administration. Survey results mirrored informal student comments: while this effort required a substantial time commitment relative to a typical course project, the learning and satisfaction derived were worth the investment. |

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.
