Course Outcomes:

After studying this course, students will be able to:

1.Understand and explain continuous time and discrete time signals and systems, in time and frequency domain

2. Apply the concepts of signals and systems to obtain the desired parameter/ representation

3.Analyse the given system and classify the system/arrive at a suitable conclu­sion

4. Design analog/digital filters to meet given specifications

5. Design and implement (assignment component)

a. the analog filter using components/ suitable simulation tools

b.the digital filter (FIR/IIR) using suitable simulation tools, and

c.record the input and output of the filter for the given audio signal

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 each module covering all the topics ofthe 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.
