The beam in some versions traces out a lopsided figure-8 pattern on its side. From Wikipedia, the free encyclopedia. Width Height Views Read Edit View history.

In the professional audio world, this method is used for realtime analysis of the phase relationship between the left and right channels of a stereo audio signal. On larger, more sophisticated audio mixing consoles an oscilloscope may be built-in for this purpose.

Rational ratios produce closed connected or “still” figures, while irrational ratios produce figures that appear to rotate.

The relation of some Lissajous curves to Chebyshev polynomials is clearer to understand if the Lissajous curve which courb each of them is expressed using cosine functions rather than sine functions.

This family pissajous curves was investigated by Nathaniel Bowditch inand later in more detail by Jules Antoine Lissajous in Not to be confused with spirographswhich are generally enclosed by a circular boundary, whereas Lissajous curves are enclosed by rectangular boundaries. Wikimedia Commons has media related to Lissajous curves. Lissajous figures were sometimes displayed on oscilloscopes meant to simulate high-tech equipment in science-fiction TV shows and movies in the s and courbr.

Lissajous figures are sometimes used in graphic design as logos. The following other wikis use this file: This article needs additional citations dr verification. Please help to improve this article by introducing more precise citations. I created it with the following GNUplo. Lissajous curves can also be generated using an oscilloscope as illustrated.

An octopus circuit can be used to demonstrate the waveform images on an oscilloscope. When the input to an LTI system is sinusoidal, the output is sinusoidal with the same frequency, but it may have a different amplitude and some phase shift.

Summary [ edit ] Description Lissajous curve 1by2. A Lissajous curve, that can be expressed in parametric form as: I created it with the following GNUplot code: The coubre 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.

I created it with the following GNUplot code:.

Please help improve this article by adding citations to reliable sources. This W3C- unspecified plot was created with Gnu plot. This page was last edited on 24 Lisssajousat The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.

Gnuplot diagrams Lissajous curves. The figure below summarizes how the Lissajous figure changes over different phase shifts. If the file has been modified from its original state, some lissajlus such as the timestamp may not fully reflect those of the original file. Retrieved from ” https: 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.

Two phase-shifted sinusoid inputs are applied to the oscilloscope in X-Y mode and the phase relationship between the signals is presented as a Lissajous figure.
