Prior to modern electronic equipment, Lissajous curves could be generated mechanically by means of a harmonograph. Gnuplot diagrams Lissajous curves. Retrieved 17 September 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. The following other wikis use this file: You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.

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. Lissajous figures are sometimes used in graphic design as logos. The following 2 pages uses this file: Description Lissajous curve 1by2.

Retrieved from ” https: From Wikipedia, the free encyclopedia. This family of curves was investigated by Nathaniel Bowditch inand later in more detail by Jules Antoine Lissajous in The arrows show the direction of rotation of the Lissajous figure. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.

A Lissajous curve, that can be expressed in parametric form as: Not to be confused with spirographswhich are generally enclosed by a circular boundary, whereas Lissajous curves are enclosed by rectangular boundaries. This licensing tag was added lissajius this file as part of the GFDL licensing update.
Lissajous curves can also be generated using an oscilloscope as illustrated.

The beam in some versions traces out a lopsided figure-8 pattern on its side. If the file has been modified from its original state, some details such as the timestamp may not lissajoys reflect those of the original file. In a sequence towards the end of an episode of Columbo entitled “Make me courbw 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 lissajous Lissajous figure. Width Height I created it with the following GNUplot code: 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.
