A Simple and didactic visualisation of musical intervales in Lissajous Curves. made with a sinthesiser and an oscilloscope, Pure Sine Waves titles express the frequency relations
used for tuning analog circuits, for example, by injecting a frequency into a circuit and watching the output on the o-scope screen, you would adjust capacitance for a stable lissajous pattern to know when the circuit was in balance.
Unbelievably cool - to WATCH the overtones in action! It's especially amazing to see the beautiful simplicity of the perfect fifth - but what takes the cake is watching the complicated crosshatch of the minor second resolve to the unison - a perfect circle!
It's for comparing phase of two signals of the same type, i.e.; two sine, triangle, or square waves input into an oscilloscope on separate channels x and y. One signal controls horizontal, and one the vertical movement of the trace dot, thus creating what you see on screen.
The best Lissajous figures I've ever seen in my life !

cool!!!
but i dont get what a lissajous graph is for.
applications?
