Remark:

Since the winter term 2021 due to the SARS-Cov-2 pandemic still is a very special one, we have decided to offer the course Digital Transmission & Signal Processing in a format considering the possibility for as well students as lecturer and tutors to give and / or consume parts of the course online using web-conference tools:

  • Course material, quizzes and assignments will be done in Moodle.
  • Lectures will be offered in MS-Teams, potentially in a hybrid fashion (lecture hall plus Teams).
  • The content will be based on our DTSP-book that is available in various formats (ipynb, pdf, html).

Course Details

Introduction

Digital Signal Transmission and Signal Processing refreshes the foundation that you have laid in "Signals and Systems / Signale und Systeme". We will, however, include the respective basics so that the various facets of your introductory study period and the potential main study period will be respected.

To establish a strong foundation, the course will give an introduction into the various building blocks that modern telecommunication systems incorporate. Sources, sinks, source and channel coding, modulation and multiplexing are the major keywords but we will also deal with dedicated concepts like A/D- and D/A-converters and quantizers in a little bit more depth.

The course will refresh the basic transformations (Fourier, Laplace) that give access to system analysis in the frequency domain, it will introduce derived transformations (Z, Hilbert) for the analysis of discrete systems and modulation schemes. It will also briefly introduce algebra on finite fields to systematically deal with error detection and correction schemes that play an important and ubiquitous role in modern communication systems.

Prerequisites

"Digital Transmission and Signal Processing" is a course during the main study period and by such requires a solid foundation of mathematics (differential and integral calculus) and probability theory. The course will, however, refresh those areas indispensably necessary for telecommunications and potential intensification courses and by this open this potential field of intensification to all participants.

Course Structure

Basic Rules

  • Please note that small changes and corrections will be applied to the lecture notes throughout the semester. If you find mistakes or have suggestions how to enhance the lecture notes we appreciate your input! 
  • Please don’t hesitate to tell us if you have any comments or suggestions related to the DTSP-Book, the Quizzes, the Tutorials or organizational issues. We will improve it soon so you can benefit from it, not only future students.
  • There will be online weekly quizzes with 5 questions for 15 minutes every week on FRIDAY from 12:15 - 12:30. These quizzes are graded individually and the points will be published online.

Lectures

  • Place: Campus E1.3, Room: HS001 (if possible; otherwise remotely via Teams)
  • Time: Tuesday 12:15 - 13:45  and Wednesday 08:30 - 10:00 (start October 19th)

Tutorial

  • Place: Campus E1.3, Room: 016 (if possible; otherwise remotely via Teams)
  • Time: Friday 12:15 - 13:45

Exam Dates

  • The exams will be held as WRITTEN exams
  • Main Exam - February 22nd, 14:00 - 16:00, E2 2 GHH
  • Re-Exam - March 30th, 10:00 - 12:00, E1 3 HS002

Task Sheets

  • Task sheets are published on Saturdays and are available online.
  • You submit your solution and work on the tasks up to and including the following tutorial.
  • During the tutorial you can discuss and evolve your solutions and get up to three additional points.

Correction

  • The quizzes and task sheets for this course will be divided into two parts (6+6 in blocks A&B respectively). It is necessary to pass both the blocks individually to be eligible for the exam.
  • Weekly Quizzes and Task Sheets:
    • Each weekly quiz are worth 5 points total, which adds up to 30/30 points total for Blocks A/B. These points can be earned individually by everyone.
    • Each task sheet contains minimum 3 tasks, which adds up to 18/18 points total for Blocks A/B. These points can be earned if you individually can demonstrate your understanding on the task during the tutorial and by your submitted solutions..
    • Final points are calculated by adding up over all quizzes and task sheets within a block.
    • You need minimum 40% in total to pass a block and must pass both block A and B to be eligible for the exam.

Exam

  • The exam contains 5 problems (each 10 points), solving 4 of them is sufficient for a 100% passing grade.
  • Minimum point threshold per exam task is 3 points.
  • (Near to) complete solutions are rewarded with 3 bonus points.

Matlab

  • Since March 2012 the UdS has a MATLAB campus license which can be used by all university students for non-commercial purposes.
  • CIP pool at Saarland university provides access
  • SSUM Signals and Systems Using Matlab package: a collection of demonstrations and exploratory applications for signal processing. It demonstrates extensively the concept of convolution, Fourier Analysis, FIR and IIR filters, modulation and much more. To use all examples the Matlab "Signal Processing Toolbox" is required (available in the CIP-room and included in Campus License).
