Lecture Digital Logic

The content on this page was translated automatically.

The course takes place in the winter semester. The exam is offered in the winter and summer semesters.

Dates: always Tuesdays between 08:00 and 10:00 in lecture hall 1603

Structure: 4 CP, 2V+1Ü, 3 SWS

The times of the exercise groups and all further information can be found in Moodle.

Changed examination modalities and times

From winter semester 18/19, Digital Logic will be offered as part of the module examination "Technical Foundations of Computer Science" for Computer Science. For all others (Electrical Engineering, Mechatronics, others) it will continue to be a separate examination. This results in

  • the duration of the examination: now 60 minutes (ET, Mecha, etc.)
  • Computer Science module examination: now 120 minutes in total (of which nominally 60 DigLog)
  • Exam date: in the winter semester at the beginning of the vacation, in the summer semester at the beginning of the semester

Please refer to the examination schedules for the exact dates.

Contents and goals

The aim of the lecture is to explain how the basic digital switching elements and the digital circuits built from them work and how they are used in more complex systems. They are the basis for microprocessors. Students should be able to plan (design), optimize and analyze simple digital circuits. The three underlying concepts are hierarchy or abstraction, state and coding.

The lecture is primarily aimed at students of computer science, electrical engineering and mechatronics in the first semester without prior knowledge. It deals with number representation and codes, Boolean algebra, design and simplification of switching networks, analysis and synthesis of switching systems through to control unit design. Modern field-programmable devices are also covered.

Group exercises (1 SWS) are offered in addition to the lecture (2 SWS). You will be supervised by student tutors in the group exercises, which are designed to consolidate the material covered in the lecture by means of practical tasks. The group size is between 20 and 30 participants. We hope to be able to guarantee sufficient supervision. In a later semester, you can also attend the practical course (laboratory) in digital technology.

The exercises themselves consist of face-to-face exercises and homework, which must be handed in within one week of the corresponding exercise.

Learning objectives: The student can

  • describe the application of digital circuits,
  • explain the basic functioning of digital circuits,
  • define binary number representations and codes,
  • explain and apply basic calculation rules,
  • explain and apply the rules of Boolean algebra,
  • apply optimization and analysis methods to example circuits,
  • plan and design simple digital circuits,
  • develop state machines from given function descriptions.

Materials

The lecture slides and exercise sheets will be published as reprints and are available in a Kassel copy store (see Moodle for details).

All course materials as well as a discussion forum can be found in the Moodle course of the lecture. Please be sure to register for this course and the corresponding exercise course.

Literature: The following textbook will be used in the lecture

Mano, M. Morris and Ciletti, Michael D.: Digital Design; Pearson International Edition; 4th ed.; 2007; ISBN 0132340437

Proof of performance

The proof of performance consists of a study achievement (preliminary examination) and an examination in the form of a written test. Please register for both parts of the examination using the registration procedure applicable to your degree program in HIS or OKA. You can only register for the written exam once we have activated your coursework (for which you must also register!).

Examination preparation (Attention: changed from WS24/25!)

Details on the preliminary examination will be announced in the lecture and in Moodle. Please register in the Moodle course for the lecture as well as for the exercise.

Examination

The written exam takes place every semester. Details on the examination modalities (duration etc.) can be found in the module handbook of your degree program.

The following aids are permitted for the exam:

Handwritten formulary (cheat sheet): one DIN A4 sheet, double-sided

Please note the changed examination periods for the summer semester (at the beginning of the semester!!!)
