B. Tech.Curriculum Undergraduate Programme

Third to Eight Semester(Applicable for batch 2006 and onwards)

Departmentof

Electrical Engineering

National Institute of Technology Srinagar- 190006

MISSION

To consolidate and promote the Human Resources and infrastructure facilities available for optimal use and further resources generation through projects of regional, continental and international relevance.

VISIONTo make Department of Electrical Engineering a Center of excellence to promote academic, research, development and consultancy services to meet the regional, national and international requirements.

PREFACEThe Regional Engineering College, Srinagar was established in 1961 on the banks of the World famous Dal Lake. It was converted into National Institute of Technology, Srinagar in July, 2003, with Deemed-to-be University Status. Consequent upon the conversion, the academic programmes were to be regulated in accordances with the NIT rules of 2002. Accordingly, the academic programmes were restructured around the credit system in which Marks System of evaluation was replaced by Letter Grade System. We have held numerous Board of Studies meetings in the Electrical Engineering Department to evolve a scheme of courses which is commensurate with the latest developments in Electrical Engineering field: The curriculum which has been developed has the following features:1. 2. 3. 4. 5. Total Number of credits of the Scheme Number of credits in each semester Number of contact hours per week in each semester Ratio between lectures and tutorials All laboratory courses are independent courses and have separate credits 6. Distribution of credits has been done as follows: 200 25 30 7:3 (around)

Humanities and Management Courses Basic Science Courses Courses offered by other Engg. Departments Departmental courses Electives

11 credits 33 credits 44 credits 92 credits 20 credits

The Major Project consists of two parts, preliminary work of 3 credits is to be done at 7th semester level and main work of 12 credits shall be done at 8th semester level. A good choice of electives is offered at 6th, 7th and 8th semester levels. Detailed syllabi have been prepared and updated for all courses.
