Course Description

Digital systems process in discrete steps real-world values previously converted into numbers. As within digital systems data are given a binary representation, what is based on both theoretical and technological grounds, digital systems are based upon logic circuits. The objective of the course is to introduce students to fundamental principles of digital systems design, starting with the elementary procedures of analysis and design. Elementary combinational and sequential components and modules are elaborated too, as well as the inclusion of digital systems in the real world.

General Competencies

Students will gain fundamental knowledge on the structure of digital systems, based on levels of characteristic logic circuits and subsystems, as well as on applying basic methods of digital systems analysis and design, both combinational and sequential. Students will be qualified to carry out basic design procedures using standard and programmable modules, under physical constraints imposed by both dynamic and electrical characteristics of circuits and their interconnections.

Learning Outcomes

  1. choose the appropriate level of standard combinational and sequential components to design simple digital circuits
  2. design simple combinational and sequential digital circuits
  3. analyze simple combinational and sequential digital circuits
  4. apply Boolean algebra as a formalism for describing of combinational and sequential digital circuits
  5. apply the VHDL hardware description language in modeling and simulation of simple combinational and sequential digital circuits
  6. identify and classify standard and programmable combinational and sequential digital circuits
  7. recognize the limitations represented by dynamic and electrical properties of digital circuits and their interconnections
