Question

Quizplus · Accepted Answer

When harmonically related signals are applied to the horizontal and vertical inputs of an oscilloscope, a Lissajous pattern is displayed. This pattern is formed by the intersection of two sine waves at right angles to each other, with the shape of the pattern depending on the frequency and phase relationship between the two signals.
