Oscilloscopes

[Drammy]

I found an oscillator that has the X-Y function where the left channel is represented by the Y axis and the right by the X axis.

If a mono sound is played through the 'scope a line appears from bottom-left to top-right and is of course in phase. When a stereo signal (eg the track I am writing) is passed though the line changes into a "cloud" but the direction of the cloud was clearly bottom left --> top right indicating that the signal is in phase. If the line changes direction by 180 degrees then the signal is considered out of phase.

Hope this answers your question!
