What is the phase shift (in degrees) between the signals, which is indicated by the Lissajous pattern given below?

What is the phase shift (in degrees) between the signals, which is indicated by the Lissajous pattern given below? Correct Answer 180

In CRO we can measure the phase difference by X-Y mode operation.

  • At a phase shift ϕ = 0° or 360°, the pattern indicated by CRO is a diagonal straight line making 45° with the X-axis.
  • At a phase shift of ϕ = 90°, the pattern indicated by CRO is a clockwise rotating circle.
  • At phase shift ϕ = 180°, the pattern indicated by CRO is a diagonal straight line making 135° with the X-axis.
  • At phase shift ϕ = 270°, the pattern indicated by CRO is an anti-clockwise rotating circle.
