This course represents a real hands-on laboratory course in introductory electronics. In it, you will learn how to use the instruments every electrical engineer needs to know: the oscilloscope, function generator and multi-meter. You will use these instruments running on your computer to measure voltages from circuits you will build from actual electrical components with measurement systems provided by National Instruments, Inc. Students will be required to purchase hardware, software and electrical parts.
This laboratory uses the terminology and knowledge of electrical engineering provided in Coursera's Fundamentals of Electrical Engineering. You can take the laboratory simultaneously with this course or afterwards. Once you learn the basics found in the laboratory course, you will know how to interface electrical circuits to measurement systems, be they analog or digital. You will have the knowledge to build live circuits and get them to work. No simulations!!
Lab Zero: Ordering the laboratory kit, opening the box and installing
the software. Most electrical engineering systems combine hardware and
software systems, and this kit follows that approach. Instruments are implemented
in software to run on your computer while the circuits and software perform
information processing. Because of delivery of the parts take time, this "lab" lasts for three weeks even though it is quite simple.
Lab One: Simple DC Circuits. Using a DMM (Digital Multi-Meter) to measure voltage, current, and resistance; an oscilloscope to display time-varying voltages; a power supply to produce constant (DC) voltages; and a function generator to produce time varying (AC) voltages.
Lab Two: AC Measurements. Characterization and measurement of waveforms using an oscilloscope. Grounding issues. Electro-acoustics—conversion of sound to voltage and back—and opto-electronics—conversion of light to voltage and back.
Lab Three: Signal Processing I: Amplifiers. Using the op-amp in various modes for creating amplifiers.
Lab Four: Signal Processing II: Filters. Building passive and active filters and measuring their transfer functions.
Lab Five: Signal Analysis and Characterization. Time-domain and frequency-domain characterization of signals, especially speech.
Lab Six: Digital Representation of Signals. A/D and D/A conversion.
Lab Seven: Digital Signal Processing I. Implementing digital filters.
Lab Eight: Digital Signal Processing II. Advanced digital filtering. Generating signals digitally. "Fancy" signal processing: speech scramblers, digital music.
Lab Nine: Final Project
This hands-on laboratory course complements Coursera's Fundamentals of Electrical Engineering. The course develops basic skills in constructing and measuring electrical circuits using modern laboratory instruments.
