Course purpose
The course will provide a basic knowledge of linear systems and how these can be used to describe effects in physical systems. Various mathematical tools for calculating the relationship between input signal and output signals of a linear system are taught.
Schedule
Due to covid-related issues, the two weeks of lectures and exercise sessions will be held over zoom. We will then switch to a hybrid format where some students will be allowed in the lecture room and some will have to attend online.

Course literature
Textbook
Signal Processing and Linear Systems
International Edition, B.P. Lathi, Oxford Univ. Press
If you have a different textbook that was used in the same course (SSY080) in the past years, likely you will find similar material.
An example of alternative book is
Signals, systems, and transforms
Phillips, Charles L.
Course design
The course includes
- lectures held by the examiner
- exercise sessions held by the teaching assistant
- project work that you (the students) will carry out in pairs
- online quizzes during the lectures
Material will be posted over Canvas. The project implementation requires the use of Matlab (that can be downloaded from the Chalmers software center). You should have a computer or smartphone to be able to reply to the quizzes.
Changes made since the last occasion
There are three main changes compared to the past year
1. Only one lecturer
2. Online quizzes during the lectures
3. Grading system for the written exam
4. Written exam and project work are now reported separately in ladok
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 solve the LTI-equation y = h * x, both in continuous and discrete time, when two of the factors are known.
- 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.

Examination form
Mandatory: Written examination + Project work (in pairs, report + presentation)
Mandatory examination is enough to have the possibility to get up to 25 / 25 points, corresponding to a final grade of 5 / 5.
Optional: online quizzes during the lectures
They give up to 4 / 25 points that can be added to the points obtained from the mandatory examination, to improve the final grade.
