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.

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.
