Instrumentation: Sensors and Signals

Lecturer: Kent Lundberg
Science requires data, and gathering good data requires interfacing useful circuitry to useful sensors. This course is an introduction to the science and practice of instrumentation. Measurement of the real world is the basis of science, engineering, manufacturing, and design. Topics covered include surveys of sensors and transducers, the design of interface circuitry, and techniques for data acquisition.

Kent H. Lundberg is an educator, consultant, and historian. He is president of Keeling Flight Hardware, Ltd., which provides design, research, and educational consulting services in the fields of aerospace, electronics, and control systems for companies, universities, and government organizations.

Since 2008, Dr. Lundberg has been a Visiting Professor at Olin College of Engineering, where he teaches courses in controls, circuit design, and instrumentation. From 2002 to 2005 and in 2011, he was a Lecturer with the Department of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology. His research and teaching interests include the application of classical control theory to problems in analog circuit design, and the development of educational toys (lecture demos, take-home laboratory kits, and tutorial computer applications) for feedback systems and control engineering.

Dr. Lundberg was the Associate Editor for History of IEEE Control Systems Magazine from 2004 to 2011. He attended M.I.T. earning a Bachelor's degree in physics in 1992, and a Ph.D. in electrical engineering in 2002. He owns 43 Tektronix oscilloscopes, and he obsessive-compulsively collects analog synthesizers, technology artifacts, and classic textbooks on radar, nuclear energy, analog computing, and control.
