This course focuses on measurements of various electrical quantities such as voltage, current, electrical power, resistance, impedance, frequency, phase, magnetic field etc.
Students in electrical and electronic fields should obtain fundamental knowledge related to electronic measurement indispensable for all experiments on electronics. The progress of measurement technique based upon digital technology is recently remarkable. Thus, students will learn the latest digital instruments for measurements so that they can measure physical quantities precisely using a computer.
By the end of this course, students will be able to
1) deal with measurement error, significant digits, SI unit system.
2) deal with analog and digital quantities obtained from measurement instruments.
3) measure electrical quantities such as voltage, current, electrical power, resistance, impedance, frequency, phase and magnetic field etc.
4) measure waveshape of electrical signal.
5) develop a measurement system using an embedded sensor.
