Aim
The aim of the course is to give the engineer fundamental knowledge in digital technique and in computer technique. The purpose is also to give practical skills in structured methods of solving problems, of construction and of seeking failure in equipments.

Knowledge and understanding
For a passing grade the student must

• be able to explain Boolean algebra and binary arithmetic.

• be able to describe the function of combinational networks and of sequential networks.

• be able to describe the principles of how a computer works at register level.

• be able to apply systematic methods of analysis and synthesis of combinational and sequential networks.

Skills and abilities
For a passing grade the student must

• be able, by programming (in the language of VHDL and C), to design a digital system consisting of programmable chips or of embedded systems.

• be able in writing, to document a construction made in VHDL or in C.

• have the fundamental knowledge to in the future, as an working engineer, incorporate and learn new low level programming languages.
