Width Height The arrows show the direction of rotation of the Lissajous figure. Two phase-shifted sinusoid inputs are applied to the lisszjous in X-Y mode and the phase relationship between the signals is presented as a Lissajous figure.

On larger, more sophisticated audio mixing consoles an oscilloscope may be built-in for this purpose. 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.

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. This family of curves was investigated by Nathaniel Bowditch inand later in more detail by Jules Antoine Lissajous in Rational ratios produce closed connected or “still” figures, while irrational ratios produce figures that appear to rotate. Retrieved 17 September Gnuplot diagrams Lissajous curves.

Prior to modern electronic equipment, Lissajous curves could be generated mechanically lisdajous means of a harmonograph.

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.

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.
