The above Lissajous pattern is observed in CRO, What is the phase difference between the applied signals? Correct Answer <span style="">180°</span>

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.
