Signals and Systems

Class Description
Signals arise in most engineering applications. They contain information about the behavior of physical systems. Systems respond to signals and produce other signals. In this course, we explore how signals can be represented and manipulated, and their effects on systems. We further explore how we can discover basic system properties by exciting a system with various types of signals.

Content
Discrete-time signals and systems. Fourier and z-Transforms. Frequency domain characterization of signals and systems. System identification. Time series analysis. Filter design.

Teaching language
Lectures and recitations in English, exam in English.

Lecture Notes     
Lecture Notes will be made available on the course website.

Problem Sets     
Problem sets will be made available online after the respective lecture. Problem sets are not graded.

Quiz    
There is an optional, graded written Quiz that may improve the final grade for the course. The Quiz covers the material of the first half of the lecture.

Programming Exercises     
There is an optional, graded Python programming assignment that may improve the final grade for the course. This assignment requires the student to understand and to apply the lecture material.

When appropriate, additional Python programming exercises will be part of the problem sets. In the quiz and the final exam, there will be specific problems about the programming exercises.


Exam
There is a written final exam during the examination session, which covers all material taught during the course, i.e. the material presented during the lectures and corresponding problem sets, programming exercises, and recitations. One A4 sheet of typed or handwritten notes is allowed. Both sides of the A4 sheet may be used. No books, calculators or other aids are allowed.

Grading
The final grade is based on the session exam, an optional in-class quiz, and an optional programming assignment.

Repetition
The exam is only offered in the session after the course unit. Repetition is only possible after re-enrolling and marks from previous semesters will not be counted.
