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.

Description Lissajous curve 1by2. In other projects Wikimedia Commons. I created it with the following GNUplo. Retrieved from ” https: This family of curves was investigated by Nathaniel Bowditch inand later in more detail by Jules Antoine Lissajous in 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.

I created it with the following GNUplot code: A Lissajous lisasjous, that can be expressed in parametric form as: The figure below summarizes how the Lissajous figure changes over different phase shifts. 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 arrows show the direction of rotation of the Lissajous figure. You may do so in any reasonable manner, but not lisssajous any way that suggests the licensor endorses you or your use.
Two phase-shifted sinusoid inputs are applied to the oscilloscope in X-Y mode and the phase relationship between the signals is lisszjous as a 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.

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. Wikimedia Commons has media related to Lissajous curves. The beam in some versions traces out a lopsided figure-8 pattern on its side. Not to be confused with spirographswhich are generally enclosed by a circular boundary, whereas Lissajous curves are enclosed by rectangular boundaries.
