3. Develop a thorough understanding on basics of ECG and EEG feature extraction.

4. Evaluate various event detection techniques for the analysis of the EEG and ECG

5. Develop algorithms toprocess and analyze biomedical signals for better diagnosis.

 

Question paper pattern:

  • Examination will be conducted for 100 marks with question paper containing 10 full questions, each of 20 marks.
  • Each full question can have a maximum of 4 sub questions.
  • There will be 2 full questions from eachmodule covering all the topics of the module.
  • Students will have to answer 5 full questions, selecting one full question from each module.
  • The total marks will be proportionally reduced to 60 marks as SEE marks is 60.
