Drawing Lissajous Curves on a Oscilloscope

Lissajous curves (http://en.wikipedia.org/wiki/Lissajous_curve) are two dimensional figures where the points (x,y) are defined by sine functions with different coefficients: x = sin(t) y = sin(at+b) By modifying a and b over the period t, a wide variety of fascinating curves can be drawn, some of which look almost 3D! For example, if y is a … Continue reading “Drawing Lissajous Curves on a Oscilloscope”
