Course Information

Digital Signal Processing, TSRT78, 2022HT

Please go to Lisam for participating in the course. The content below is only for introduction.

Course Description

This course describes the most important methods and algorithms for signal processing. There is a strong focus on being able to apply these to signals of various kinds. Topics include: discrete Fourier transform (DFT), signal modeling (both in the frequency and in the time domain), estimating models, spectral estimation, Wiener filtering, Kalman filtering and adaptive filtering. The course will also discuss relevant applications of signal processing, including for example, adaptive noise cancellation and submarine tracking.

Course Structure

This course gives 6hp (of which 1hp are labs). The course structure is as follows:
  • Lectures: 14 (including invited speakers from the industry)
  • Exercises sessions: 12
  • Labs: 2 mandatory labs
  • Exam: Exam (4 hours), including both written and computer problems
Further information about the lectures, exercise sessions, and labs is available on Lisam under course TSRT78.
  • The use of computers is highly integrated in the course and more than half of the exercises take place in ISY's computer labs. More information about the computer labs is available here.
  • The computer and Matlab are "allowed aids" during the exam. The exam takes place in ISY's computer labs.
  • All students will have personal accounts and in this way have unlimited access to the computer labs also outside the scheduled time. In order to enter the computer labs and Laboteket (where the two labs takes place), you will need your LiU-card.
  • Many of the exercise problems requires the use of Matlab for solving. Matlab can be downloaded from the student portal.
