M-803-A INSTRUMENTATION AND MEASUREMENT

Introduction to Instrumentation

Major elements of a measurement system. Order, type of signals, response of instruments. Importance of sensors in measuring system. Errors and response characteristics of sensors. Measurement error.

Measurement Techniques

Signal conditioning: Amplification and noise filtering, impedance matching, Wheatstone Bridge technique. Digital signal processing: Sampling rate, aliasing, discretization, A/D and D/A converters, frequency content of a signal, concept of FFT. Common measuring instrument: Multimeters, oscilloscope, spectrum analyzer, display and recorder, plotter. Statistical analysis of data: Concept of normal distribution, mean and variance (standard deviation).
