EE 302 – Digital Circuits

EE 302 – Digital Circuits; Weekly hours: 2+2, ECTS: 6
This course introduces students to the basic concepts of digital circuits and systems, including both analysis and design synthesis. The course provides the students with foundations of digital circuits design and teaches them the tools needed to analyze, design, and develop modern digital control circuits and systems. More specifically, they will become familiar with the terminology of digital electronics. The theory and practical applications of combinational and sequential logic will be covered. Students will get acquainted with various levels of various digital systems, starting with the simple logic circuits up to basic hardware description, used in computer architecture. The lectures start with fundamentals of binary arithmetic and systems, learning also other number systems, codes and their mutual conversions. In particular, the student will learn to apply theory to the solution of logic design problems and will become proficient in the use of Boolean algebra to analyze and synthesize digital circuits. Also, the student will be able to design circuits of logic gates with specified relationships between input and output signals, using them in a combination with circuits of logic gates. Exercises are performed in a classroom on solving problems. During the semester, the practical work is performed continuously in a computer laboratory using simulation software, WEB educypedia animations and Java applets for visualization.
