Course Outcomes:

At the end of the course the student will be able to:

• Explain physical interpretation of sampling theorem in time and frequency domains.
• Evaluate the impulse response of a system.
• Perform convolution of given sequences to evaluate the response of a system.
• Compute DFT and IDFT of a given sequence using the basic definition and/or fast methods.
• Provide a solution for a given difference equation.
• Design and implement IIR and FIR filters.

Conduct of Practical Examination:

1. All laboratory experiments are to be included for practical examination.

2. Breakup of marks and the instructions printed on the cover page of answer script to be strictly adhered by the examiners.

3. Students can pick one experiment from the questions lot prepared by the examiners.

4. Change of experiment is allowed only once and 15% Marks allotted to the procedure part to be made zero.
