1 Question Questions nimation: Lissajous figures on an oscilloscope with 90 degrees phase shift This question consists of a series of images (one per page) that form an animation. Flip the pages with your fingers to view this animation (or click on the next button on your viewer) frame-by-frame. The following animation shows how two sinusoidal voltages with 90 degrees phase shift between them can draw a Lissajous figure on the screen of an oscilloscope.

12 Notes Notes The purpose of this animation is to let students study the evolution of Lissajous figures and see how they are created from the interrelationship between two sinusoidal waveforms. Similar to experimentation in the lab, except that here all the data collection is done visually rather than through the use of test equipment, and the students are able to see things that are invisible in real life.
Using an Oscilloscope
Using an Oscilloscope The oscilloscope is used to measure a voltage that changes in time. It has two probes, like a voltmeter. You put these probes on either side of the thing that you want to measure
