HOME 学部後期課程 Information and Measurement

# Information and Measurement

The primary goal of the course is to provide students with an integrated view of how the basic concepts of mathematics and physics are applied to collecting information about a system. Upon successful completion of this course, the student will have:
-acquired a basic knowledge of the physics of information,
-gained an understanding of the physical principles of a broad range of modern sensors,
-developed skills in data analysis and system modeling.
