This course covers instrumentation and the use of experiments to evaluate real-world systems. Basic, practical electronics, computer data acquisition, programming and signal conditioning are taught and then applied in experiments that investigate heat transfer, fluid mechanics, thermodynamics, and structural dynamics. Lab sessions will be held in the Mechatronics Design Lab in the Ford Design Center room B100.
