Question A-003-005-007

When using Lissajous figures to determine phase differences, an indication of zero or 180 degrees is represented on the screen of an oscilloscope by:

Correct Answer

a diagonal straight line

Explanation

If two sinusoidal signals of the same frequency are in phase (0°) or 180° out of phase, the Lissajous pattern is a straight diagonal line. The slope indicates the phase (e.g., positive slope for 0°, negative for 180°).
