[Course Objectives]
Most information and communication systems in which computers are organically integrated are composed of information circuits based on digital signal processing.
The objective of this course is to provide students with fundamental knowledge of digital information circuits.

The course begins with an overview of the switching operation of transistors and basic gate-level circuits.
It then covers combinational circuits such as decoders and arithmetic circuits, followed by an explanation of sequential circuits including counters and registers.
Finally, the principles of A/D and D/A conversion circuits are introduced.

[Learning Outocomes]
Upon successful completion of this course, students will be able to:

1. - Explain both qualitatively and quantitatively the principles of switching operation of bipolar transistors and MOSFETs.
2. - Analyze and design arithmetic circuits, decoders, multiplexers, registers, and counters.
3. - Simplify combinational logic circuits and apply these techniques to the analysis and design of sequential circuits.
4. - Explain the operating principles of A/D and D/A conversion circuits.

[Lecture Contents]
Digital electronic technologies that support computer systems have advanced significantly, and signals that were traditionally handled by analog electronic circuits are increasingly being processed digitally.
In addition, the integration density of digital electronic circuits has grown exponentially, resulting in large-scale and highly complex system architectures.

Nevertheless, even ultra-high-density integrated computer systems are essentially composed of combinations of a limited number of basic digital circuits.
Therefore, by fully understanding the characteristics and operation of these fundamental circuits, students are able to analyze and design even highly complex digital systems.

This course aims to provide students with universal and fundamental knowledge of digital circuits.
The course begins with an in-depth study of the operating principles of basic digital circuits, focusing on logic gates down to the transistor level.
It then covers the design and analysis of basic combinational and sequential circuits—such as decoders, multiplexers, arithmetic circuits, counters, and registers—using numerous practical implementation examples.
Finally, A/D and D/A conversion circuits are also introduced.

Please follow Guidelines on the Use of Generative AI in Education at the University of Hyogo.
Reports are expected to be prepared by the students themselves; therefore, reports may not be created solely using generative AI.
If generative AI is used partially, the specific portions where it is used must be clearly indicated.
When studying at home for preparation or review, students may actively use generative AI tools if necessary.
However, students should not rely on the outputs of generative AI without verification, and are expected to confirm their accuracy and use them only after fully understanding the content.

[Preparation]  
Review of the materials distributed in advance (2 hours  × 15)

[Review]  
Re-reading of the textbook to deepen understanding and reinforce the lecture content (2 hours × 15)

For in-class assignments, explanations will be provided after the submission of answers.

[Grading Criteria]

In this class, grades are determined by the level of achievement of the abilities described in the course objectives and learning outcomes.
The final grade will be determined based on the following components: midterm examination (40%), final examination (40%), and in-class exercises and assignments (20%).
Based on the total score, grades will be assigned as follows: S (90 points or above), A (80 points or above), B (70 points or above), and C (60 points or above). Students who receive grades of S, A, B, or C are awarded course credit.

For in-class assignments, explanations will be provided after the submission of answers.
For the midterm examination, the results will be announced in a subsequent class, and sample solutions will be explained during the lecture.
For the final examination, the results will be disclosed to students upon request.

It is preferable that students have completed "Electronic Circuits I", "Fundamentals of Computer Science", and "Discrete Mathematics" prior to taking this course.
