Assessment Rationale And Relationship

The examination will help students to demonstrate the core understanding of course material, analysis and synthesis skills to novel situations related to DSP. Students’ lab report reflect their in-depth learning related to the contents delivered during lecture, it also demonstrate the conceptual learning by the way they deal with the problems assigned to them in labs.
