Course description and aims

This course focuses on the fundamentals of digital circuit. Topics include binary number, logical algebra and its calculation, basic logic gate, combinational logic circuit, sequential circuit, arithmetic circuit and synchronous logic circuit. Most of electronic devices consists of digital circuit technique. By combining lectures and exercises, the course enables students to understand and acquire the fundamentals of logic circuit so that students can design a simple circuit. Students will experience the satisfaction of solving practical circuit problems by using their knowledge regarding a logic circuit acquired through this course.

Student learning outcomes

By the end of this course, students will be able to:
1) Understand and explain the fundamentals of logical algebra and logic gates.
2) Analyze and design a simple combinational logic circuit.
3) Analyze and design a simple sequential logic circuit.
4) Analyze and design a simple arithmetic logic circuit.


Digital circuit, logic circuit, logical algebra, combinational logic circuit, flip-flop, sequential circuit, operational circuit

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills
・Applied specialist skills on EEE

Class flow

At the beginning of each class, solutions to exercise problems that were given at the previous class are reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes. In the first half lectures we will take interactive exercises using Handbook.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.



Reference books, course materials, etc.

All lecture materials will be uploaded to OCW.

Assessment criteria and methods
