4. Aim • Teaching DSP on TMS processors together with theory course on DSP. • Major research and development effort using DSPs in current areas of Wireless Communications, Image Processing Networking,Embedded systems,Systems &Control. • Training programs for industries. • Taking up industrial,application specific • projects. • Consultancy . • Platform for Industry – Institute Interactions

5. 2. Development Activities • 1996 • Laboratory development. • Basic DSP experiments. • Mini – Projects. • 1997 • Complete set of basic experiments were executed. • Some students started on their major projects like MPEG-I Audio Encoder / Decoder etc. using TI DSPs. • Laboratory course, supplementing lectures were tried out on graduate and senior under-graduate students. • CEP course for industry on advanced topics in DSP.

6. 1998 • Third prize at national level TI-DSP challenge contest won by a group of IITB students. • TI provided some personal computers. • TI supported course for faculty from VJTI was organized. • IEEE(Mumbai section)-DSP workshop . • TI supported CEP course on Wavelets for industry. • Compulsory DSP lab. Course introduced for 4th year dual-degree students. • In house CEP course at Duettech Delhi (Noida) related to VLSI and DSP was organized (VMG, ANC, DKS). • CEP course on Wavelets for industry.

7. On other occasions, courses for faculty/Employees of other institutes were organized. • Also every year students from other IITs/are invited for their summer project in DSP and related fields of communication. • If possible, we have also supported students from other nearby colleges for their final year projects. • Students from engineering colleges are invited to study DSP and carry out short term projects.
