Summary

Measuring physical quantities lies at the heart of how engineers and scientists interact with the world around us. This course introduces most common approaches to measuring and reporting quantities such as temperature, humidity, force, acceleration, strain etc. using modern types of sensors.

Content

Sensors and conditioning ciruits. Introduction to transducers, sensors and actuators. Active and passive sensors and their conditioning.

Modeling a measuring system. Measurands and functional components of a measuring system, interfering and modifying inputs, static and dynamic characteristics, identification of transfer function, loading effects.

Noise estimation and reduction. Extrinsic noise, capacitive coupling, magnetic coupling, common mode voltage. Intrinsic noise and noise specifications. Noise reduction, connecting, asymmetric and differential amplifiers, instrumentation amplifiers. Modulation-demodulation, lock-in amplifier.

Analysis of Measurement results. Error attributes, rules of errors composition. Sources and measuring devices. Data presentation. Analog and digital multlimeters specifications.

Comparing measured data. Statistical measuring parameters and their estimation. Random variable and realization, population and sampling. Main distribution, confidence interval, estimation of systematic and random errors by hypothesis tests. Test; retest and reliability of measurement.

Data acquisition. General specification. Sampling, coding, quantication, data conversion (D/A and A/D), multiplexing.
