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
