An octopus circuit can be used to demonstrate the waveform images on an oscilloscope. Retrieved 17 September Retrieved from ” https: 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.

A Lissajous curve, that can be expressed in parametric form as: I created it with the following GNUplot code:. I created it with the following GNUplo.

This page was last edited on 24 Octoberat I created it with the following GNUplot code: A Lissajous curve is used in experimental tests to determine if a device may be properly categorized as a memristor. This W3C- unspecified plot was created with Gnu plot. Views Read Edit View history. In the professional audio world, this method is used for realtime analysis coirbe the phase relationship between the left and right channels of a stereo audio signal.
Lissajous curves can also be generated using an oscilloscope as illustrated. Rational ratios produce closed connected or “still” figures, while irrational ratios produce figures that appear to rotate. Lissajous figures are sometimes used in graphic design as logos. Summary [ edit ] Description Lissajous curve 1by2. The arrows show the direction of rotation of the Lissajous figure.
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 coufbe as the clock in the camera, and it may be completely wrong.
Not to be confused with spirographswhich are generally enclosed by a circular boundary, whereas Lissajous curves are enclosed by rectangular boundaries. This article lissajois additional citations for verification.
Lissajous figures were sometimes displayed on oscilloscopes liwsajous to simulate high-tech equipment in science-fiction TV shows and movies in the s and s. Please help to improve this article by introducing more precise citations.

In a sequence towards the end of an episode of Columbo entitled “Make me lissajoks Perfect Murder”, the detective sits watching Lissajous curves displayed to music courhe monitors in a TV outside broadcast van. November Learn how corube when to remove this template message. Wikimedia Commons has media related to Lissajous curves. 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.
