Course purpose

The course will provide fundamental knowledge about linear systems and how they can be used to describe physical phenomena. Different mathematical tools which can be used to calculate the relationship between input and output signals in linear systems will be presented.

However, in few occasions, you will have a lecture on Wednesday in a different room (please check TimeEdit). This is because there is some overlap with a course I am attending.

 

Course literature

Textbook

Signal Processing and Linear Systems

Second Edition
B. P. Lathi and Roger Green

ISBN: 9780190299040

The textbook has been changed compared to the previous year because the old one is unavailable.

If you have a different textbook that was used in the same course (SSY081 or SSY080) in the past years, likely you will find similar material.

Example of alternative books are

Signal Processing and Linear Systems
     International Edition,  B.P. Lathi, Oxford Univ. Press

Signals, systems, and transforms

Phillips, Charles L.

 

Course design

The course includes

  • lectures held by the examiner
  • exercise sessions held by a teaching assistant (Tiffany)
  • project work that you (the students) will carry out in teams of 4 students
  • online quizzes outside the lectures (graded)
  • online quizzes within the lectures (not graded)

Material will be posted on Canvas. The project implementation requires the use of Python. You should have a computer or smartphone to be able to reply to the quizzes.

Changes made since the last occasion

There are two main changes compared to the past year

  1. We have a new textbook, because the old one became unavailable
  2. We have 2 teaching assistants instead of 3

Learning objectives and syllabus

Learning objectives:

•    identify and give examples of different signal types, such as periodic signals, absolutely summable/integrable signals, finite energy signals and band-limited signals.
•    identify important system properties, such as linearity, shift-invariance, causality and BIBO-stability, in examples.
•    select the appropriate transforms (Fourier series, Continuous and Discrete time Fourier transform, Laplace transform, Discrete Fourier transform and z-transform) for a given problem.
•    compute the transforms of commonly used signals in the course.
•    apply transform techniques to find the output of a LTI system, both in continuous and discrete time.
•    identify the Nyquist rate of a band-limited signal.
•    employ the Sampling Theorem to reconstruct band-limited signals from sampled data.
•    interpret plots of the DFT (Discrete Fourier Transform) of a sampled signal.
•    interpret the effect of filters on a given signal.

Study plan

Examination form

Mandatory: Written examination + Project work (in teams of 4, report + presentation)

Written exam (4 h)

  • 10 questions (‘quick’ answers, type A, 1 point each), 10 points in total (1x10)

4 points required for passing

  • 3 questions (calculation, type B, 5 points each), 15 points in total (3 x 5)

5 points required for passing

  • Points of type A questions + Points of type B questions + Optional bonus points >= 12 for passing

Points

Final grade

U

5

Written exam is enough to have the possibility to get up to 25 / 25 points, corresponding to a final grade of 5 / 5.

Allowed material during the written exam:
•    A calculator (among those approved by Chalmers)
•    Two A4 pages where you can write by hand whatever you believe may help you during the exam (e.g., exercises that have been solved in class, definitions, etc). You can write on both sides of the sheet, so you can have 2 pages of handwritten notes in total.
•    In addition, you are provided with the following tables

o    Trigonometric identities
o    Fourier transforms
o    Fourier transform operations
o    Laplace transforms
o    Laplace transform properties
o    z-Transform
o    z-Transform operations

 

Optional: online quizzes

They give up to 3 / 25 points that can be added to the points obtained from the mandatory examination, to improve the final grade.

 

Project work 

  • You work in groups of 4 and write a common report
  • The report should be written in English
  • Each group has to submit report and code through Canvas
  • It is very useful to implement the project during the course, because it helps to understand the course content. However, we are aware this is not always possible, therefore…
  • There are three deadlines for report submission (18th of October, 3rd of January, 22nd of August)
  • If you submit by the 18th of October, the project discussion is scheduled in the period 21st to 30th of October (time slots are available on the Canvas calendar)
  • During the project discussion, we will discuss about what you have done in the project and how it relates to what we have studied in the course
  • You do not need to prepare any slide for the oral presentation. We will ask questions depending on your report/code
  • Each team member is supposed to be able to justify the choices made in the project implementation and to “defend” their solution
  • The grade (UG) is individual
  • It may happen that there is something to be changed in the report/code. You will be granted 10 days to implement the changes
