Introduction. States and state spaces are important concepts for construction of digital systems. Examples from different areas illustrate how these concepts leads to a formalisation of informal problem descriptions.

Basics. The base for all constructions with digital circuits is the Boolean algebra. This is introduced from abstract algebra and Boolean rings. Some important theoretical concepts of Boolean functions are discussed. Special Boolean functions, linear and affine functions, and applications within logic is presented.

Combinational circuits. Realisations of, for example, the next state function in sequential circuits involve constructions of combinational circuits with one or several outputs. Methods for circuit realisations and minimisation are discussed. Different applications are studied and specific problems that arise, for example delay, is mentioned.

Sequential circuits. Synchronous sequential circuits are introduced as a way to realise the behaviour of the state transition graphs. Aspects like state assignments and state minimisation is discussed.

Linear sequential circuits. Linear sequential circuits are of special interest in many applications. A richer algebraic structure allows more powerful methods for constructions. Canonical forms, controllability, and observability is discussed together with analysis of linear feedback shift registers.

Modern digital design: Basics on how gates and other components are constructed on transistor level and a brief introduction to tools for digital design using a hardware describing language, for example VHDL. Basic syntax in a hardware describing language.

Examination details

Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)
Assessment: Examination through approved labs part, a written exam and home assignments.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
