Course Description

You can find many applications in various areas if you understand the fundamental and important subjects of the analog electronic circuit system which consists of an electronic device. Therefore, you will learn the fundamental concepts of amplifier circuits and equivalent circuits essential for understanding the analog electronic circuit system, and will be taught about the analog electronic circuits for various applications. You should often review subjects taught in class in the homework reports in order to improve understanding of the analog electronic circuits.
This subject puts emphasis on lectures, therefore, another subject "Exercises in Electronic Circuits" has practical training with exercise of various electronic circuits.
This subject corresponds to the diploma policy DP4E.

Course Objectives

According to DP4E, our aim is the study of fundamental and important subjects concerning analog electronic circuit systems which are essential to electronic engineers. In details, students will understand the fundamental and important subjects of the analog electronic circuit system which consists of an electronic device, and will be able to explain and calculate the electronic circuits.

Grading Policy

Those who attend 10 or more lectures of the total 15 lectures will be given the qualifications of the regular examinations. The overall grade of this course will be decided based on the sum of total 100 points of the midterm exam (40 points), the final exam (40 points), and the score of the exercises (20 points), and those whose grade is 60 or more will pass.
The score of the exercises will be proportional to the number of the passed exercises submitted before each due date, and the maximum score of the exercises is 20 points.
For feedback, the answer of the exercise will be explained right after submitting it, and the exercise will be corrected and returned in the later session. Each final due date of the exercise is the date of the class a week later. No delay of submitting the exercises are allowed.

For reviews of each class, students must do the exercises in LMS (about 2.0 hour).

Note

This subject will keep pace with another subject called "Exercises in Electronic Circuits." To understand thoroughly the electronic circuit theory studied in this subject, you should also take "Exercises in Electronic Circuits" in addition to this subject.
The students who attend this subject are supposed to finish the electrical circuits, and are at least supposed to be able to calculate direct current circuits.
This subject may show many writings on the blackboard during lecture, therefore, please understand it and do your best at this subject.
If you are planning to take "Experiments in Fundamental Electronics 1 or 2," or "Experiments of Electronics 1 or 2," you should attend this subject.
LMS will be used in this subject.
