Lissajous Pattern on a Sound Card Oscilloscope & Signal GEN

The easiest way to demonstrate Lissajous Pattern in class is to use a sound card oscilloscope and signal generator. The dual-channel signals generated by the sound card signal generator can be fed into the input of the sound card oscilloscope through the loopback established at the sound card mixer level using software configuration without any external physical cable connection. You can do it with just a laptop or tablet PC.

I used a very well equipped electronics lab in the high school radio club. I got about these figures through experiments with signal generators and oscilloscopes. And I'm using these concepts in my adult life as an engineer.
