Course Details

Introduction

Digital Signal Transmission and Signal Processing refreshes the foundation that you have layed in "Signals and Systems / Signale und Systeme". We will, however, include the respective basics so that the various facettes of your introductory study period (Bachelor in Computer Science, Vordiplom Computer und Kommunikationstechnik, Elektrotechnik or Mechatronik) and the potential main study period (Master in Computer Science, Diplom Ingenieur Computer und Kommunikationstechnik or Mechatronik) 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 indispensibly necessary for telecommunications and potential intensification courses and by this open this potential field of intensification to all participants.

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 lecture notes, task sheets, exercises or even organization things. We will improve it soon so you can benefit from it, not only future students.
• There will be printed weekly quizzes with 5 questions for 15 minutes every week on THURSDAY from 08:30 - 08:45. These quizzes are graded individually and the points will be published online.

Exam Dates:

• Main exam - TBA
• Re-Exam - TBA

Exercise Group

• Place: Campus C6. 3. Room: 9.05
• Time: Thursdays, 08:30 - 10:00
• During the exercises you will be asked to demonstrate your understanding of the task sheet problems
• You are free to attend your preferred exercise group.

Task Sheets

• Task sheets are issued on Tuesdays after the lecture and are available online.
• You do not have to submit the solutions, instead work on the tasks until the following tutorial.
• During the tutorial you can demonstrate your understanding on the task sheet questions and get an additional 1 point on every task you have contributed individually.

Correction

• The quizzes and task sheets for this course will be divided into two parts (6 in each block 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 points total for all quizzes in each block. These points can be earned individually by everyone.
  • Each task sheet contains minimum 3 tasks, which adds up to 18 points total for all tasks in each block. These points can be earned only if you individually can demonstrate your understanding on the task during the tutorial.
  • Final points are calculated by adding up over all quizzes and task sheets within a block.
  • You need minimum 20 points in total to pass a block and must pass both block A and B to be eligible for the exam.

Exam

• 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.
• Faultless solutions are rewarded with 3 points.
• Schedule
  • Main exam - TBA
  • Re-Exam - TBA
