Signals and Systems

Learning Outcomes

  1. Classify signals
  2. Explain and apply tests to unknown systems in order to classify the systems into known categories
  3. Interpret and compare the properties of the F ourier Transform, the Laplace Transform and the Z-Transform
  4. Apply methods to find response of LTI time discrete and time continuous systems in time domain
  5. Apply Laplace and z- transform to find response of LTI time discrete and time continuous systems
  6. Analyze transfer functions and frequency responses and present the properties of the systems
  7. Analyze MIMO systems described with state equations
  8. Analyze and implement linear systems using block diagrams
  9. Explain the relation between continuous and discrete signals and systems

Independent assignments




Grading Method

By decision of the Faculty Council, in the academic year 2019/2020. the midterm exams are cancelled and the points assigned to that component are transferred to the final exam, unless the teachers have reassigned the points and the grading components differently. See the news for each course for information on knowledge rating.
