Design of New Demonstrator about Lissajous Figure

A sine wave whose frequency is f is obtained from the Wien bridge oscillator.Through corresponding signal conditioning circuits,phase-shifted sine waves with frequencies being f,2f and 3f are obtained respectively.The synthesis Lissajous figure whose frequency ratios are 1:1,1:2 and 1:3 can be showed by oscilloscope.Frequencies f,2f and 3f sine wave signal are from the same department of the relevant signals and the presentation graphics are stable with good effect.The new demonstrator solves the synthesis Lissajous figure graphics scrolling problem arising from the traditional method.
