Digital Design

A kötelező előtanulmányi rend az adott szak honlapján és képzési programjában található.

This subject is an overview of engineering, design, construction, testing and operation of electronic systems for space. Nevertheless, this knowledge is well applicable also in design of high reliability terrestrial equipments that are operating under extreme environmental conditions. System concepts of big space structures like satellites and probes and the problems of smaller units are also discussed. The theory and practice of space communications, the design and parts selection for high reliability electronics, the effects of interplanetary space and radiation, the mechanical construction problems and space related analogue and digital electronics are also highlighted. The lectures are extended with practice to deepen the knowledge and resolve practical problems.

Weekly 2 lecture hours and 1 hour practice.

During the term:

Obtain the mid-semester mark by writing the mid-semester test achieving at least the mark “sufficient”.

In the examination period: 

Written exam.

There is no separated course for IMSc education, but additional consultation is ensured for the students. IMSc scores can be gained by solving the IMSc task on the test an during the written examination. Furtheremore an extra homework task is available to acquire additional IMSc scores.

According to the credit number of the subject 20 IMSc scores can be gained (15 points during the semester and 5 points on the exam):

• IMSc task on the test: 5 points
• Extra IMSc homework: 10 points   
• Exam IMSc task: 5 points

During the test and exam IMSc scores can be gained by solving the IMSc task. This task is only evaluated if the result of the base exercises has grade (5). 

By submitting an extra IMSc homework by the end of the replacement week additional 10 points can be gained. The points are given only if the final result of the student is excellent (5).

Getting IMSc scores also ensured for students not attending on the course.
