Not to be confused with spirographswhich are generally enclosed by a circular boundary, whereas Lissajous curves are enclosed by rectangular boundaries. The following other wikis use this file: When the input to an LTI system is sinusoidal, the output is sinusoidal with the same frequency, but it dee have a different amplitude and some phase shift.

If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.
The arrows show the direction of rotation of the Lissajous figure. Views Read Edit View history.
Wikimedia Commons has media related to Lissajous curves. An octopus circuit can be used to demonstrate the waveform images on an oscilloscope. Rational ratios produce closed connected or “still” figures, while irrational ratios produce figures that appear to rotate.
This W3C- unspecified plot was created with Gnu plot. Width Height A Lissajous curve dourbe used in experimental tests to determine if a device may be properly categorized as a memristor.

In a sequence towards the end of an episode of Columbo entitled “Make me a Perfect Murder”, the detective sits watching Lissajous curves displayed to music on monitors in a TV outside broadcast van.

The relation of some Lissajous curves to Chebyshev polynomials is clearer to understand if the Lissajous curve which generates each of them is expressed using cosine functions rather than sine functions. Lissajous figures were sometimes displayed on oscilloscopes meant to simulate high-tech equipment in science-fiction TV shows and movies in the s and s.

The visual form of these curves is often suggestive of a three-dimensional knotand indeed many kinds of knots, including those known as Lissajous knotsproject to the plane as Lissajous figures. Prior to modern electronic equipment, Lissajous curves could be generated mechanically by means of a harmonograph.
