* SYDE 292 Circuits, Instrumentation and Measurement Instructor: Prof. Dan Stashuk DC 2613 Ext 32982 stashuk@pami.uwaterloo.ca Objectives: Based on E M field concepts define circuit components and introduce circuit concepts. Introduce instrumentation components necessary for making electrical analog measurements and digitally acquiring these measurements. Discuss how these components are configured for making measurements and possible sources of measurement errors. E M Field Concepts: electric and magnetic fields charge, electric fields, voltage current magnetic fields resistance, capacitance, inductance OUTLINE OUTLINE Maxwell’s Equations OUTLINE Gauss’s Law Maxwell’s Equations OUTLINE Gauss’s Law Ampere’s Law Maxwell’s Equations OUTLINE Gauss’s Law Ampere’s Law Faraday’s Law Maxwell’s Equations OUTLINE Gauss’s Law Ampere’s Law Faraday’s Law Gauss’s Law for Magnetism Maxwell’s Equations Circuit Components: voltage and current sources resistors, capacitors, inductors Circuit Concepts: voltages and currents nodal and mesh analysis voltage and current division input and output impedance loading effects transfer functions frequency response OUTLINE Instrumentation (measurement tools ): Operational amplifiers ideal vs real characteristics Operational amplifier circuits Instrumentation amplifiers OUTLINE Instrumentation (measurement tools ): Transducers Active Passive Interfacing Linearization OUTLINE Instrumentation (measurement tools ): Filters Why? Passive vs active Active 2nd order circuits OUTLINE Instrumentation (measurement tools ): A/D and D/A converter circuits how? OUTLINE Measurement: The Data Acquisition Channel analog signal detection analog signal conditioning (processing) sampling and digital conversion sources of error OUTLINE *
