Course Description

The aim of this course is to help students acquire an understanding of the communication systems as a mechanism for communicating audio and video to a distant place. Students will learn about mobile and optical communication technologies and systems that are the basis of today's information society.
Specifically, we will acquire necessary skills and knowledge on DP4E.

Course Objectives

1. Students be able to explain the outline of communication systems and typical technologies.
2. Students be able to explain the mechanism of analog modulation / demodulation and digital modulation / demodulation.
3. Students be able to explain the relay method that is indispensable for microwave communication.
4. Students be able to explain the principles and performance indicators of radar.

Grading Policy

Evaluation is based on 70% test, 20% report, and 10% presentation. The presentation will be a report of the matters investigated in the group work.
An example of the answer for Test 1 will be explained in the 9th class, and an example of the answer for Test 2 will be posted on the LMS. It will be give feedback on test answers that are important to the evaluation.

Textbook and Reference

TextbookThe teaching materials will be posted on the LMS by the teacher. The materials will be posted on the LMS at least 2 days before class.

The materials used in the class will be posted on the LMS at least two days in advance, so please prepare the teaching materials thoroughly before attending the class. (about 1 hour)
Please make an out-of-lesson report by reviewing the lesson and investigating related matters. (about 2 hours) It will be student submit an out-of-lesson report.


Lessons are mainly lecture-style, but we ask you to create an out-of-lesson report that investigates related items.
Have them investigate and present related items in group work.
Student need to take both tests 1 and 2. Absences without contact will not be credited.
Since the lesson content has changed recently, it may be reviewed depending on the situation.
